Welcome to the Future of Cloud Native Java

with 3 comments

Today, with the release of Jakarta EE 8, we’ve entered a new era in Java innovation.

Under an open, vendor-neutral process, a diverse community of the world’s leading Java organizations, hundreds of dedicated developers, and Eclipse Foundation staff have delivered the Jakarta EE 8 Full Platform, Web Profiles, and related TCKs, as well as Eclipse GlassFish 5.1 certified as a Jakarta EE 8 compatible implementation.

To say this a big deal is an understatement. With 18 different member organizations, over 160 new committers, 43 projects, and a codebase of over 61 million lines of code in 129 Git repositories, this was truly a massive undertaking — even by the Eclipse community’s standards. There are far too many people to thank individually here, so I’ll say many thanks to everyone in the Jakarta EE community who played a role in achieving this industry milestone.

Here are some of the reasons I’m so excited about this release.

For more than two decades, Java EE has been the platform of choice across industries for developing and running enterprise applications. According to IDC, 90 percent of Fortune 500 companies rely on Java for mission-critical workloads. Jakarta EE 8 gives software vendors, more than 10 million Java developers, and thousands of enterprises the foundation they need to migrate Java EE applications and workloads to a standards-based, vendor-neutral, open source enterprise Java stack.

As a result of the tireless efforts of the Jakarta EE Working Group’s Specification Committee, specification development follows the Jakarta EE Specification Process and Eclipse Development Process, which are open, community-driven successors to the Java Community Process (JCP) for Java EE. This makes for a fully open, collaborative approach to generating specifications, with every decision made by the community — collectively. Combined with open source TCKs and an open process of self-certification, Jakarta EE significantly lowers the barriers to entry and participation for independent implementations.

The Jakarta EE 8 specifications are fully compatible with Java EE 8 specifications and include the same APIs and Javadoc using the same programming model developers have been using for years. The Jakarta EE 8 TCKs are based on and fully compatible with Java EE 8 TCKs. That means enterprise customers will be able to migrate to Jakarta EE 8 without any changes to Java EE 8 applications.

In addition to GlassFish 5.1 (which you can download here), IBM’s Open Liberty server runtime has also been certified as a Jakarta EE 8 compatible implementation. All of the vendors in the Jakarta EE Working Group plan to certify that their Java EE 8 implementations are compatible with Jakarta EE 8.

 All of this represents an unprecedented opportunity for Java stakeholders to participate in advancing Jakarta EE to meet the modern enterprise’s need for cloud-based applications that resolve key business challenges. The community now has an open source baseline that enables the migration of proven Java technologies to a world of containers, microservices, Kubernetes, service mesh, and other cloud native technologies that have been adopted by enterprises over the last few years.

As part of the call to action, we’re actively seeking new members for the Jakarta EE Working Group. I encourage everyone to explore the benefits and advantages of membership. If Java is important to your business, and you want to ensure the innovation, growth, and sustainability of Jakarta EE within a well-governed, vendor-neutral ecosystem that benefits everyone, now is the time to get involved.

Also, if you’re interested in learning more about our community’s perspective on what cloud native Java is, why it matters so much to many enterprises, and where Jakarta EE technologies are headed, download our new free eBook, Fulfilling the Vision for Open Source, Cloud Native Java. Thank you to Adam Bien, Sebastian Daschner, Josh Juneau, Mark Little, and Reza Rahman for contributing their insights and expertise to the eBook.

Finally, if you’ll be at Oracle Code One at the Moscone Center in San Francisco next week, be sure to stop by booth #3228, where the Eclipse community will be showcasing Jakarta EE 8, GlassFish 5.1, Eclipse MicroProfile, Eclipse Che, and more of our portfolio of cloud native Java open source projects.

The Cloud Native Imperative — Results from the 2019 Jakarta EE Developer Survey

The results of the 2019 Jakarta EE Developer Survey are out. Almost 1,800 Java developers from around the world have spoken. Taken together with the engagement and response to my recent posts on the future of Jakarta EE (see my latest blog here), the survey makes clear the developer community is focused on charting a new course for a cloud native future, beginning with delivering Jakarta EE 8. The Java ecosystem has a strong desire to see Jakarta EE, as the successor to Java EE, continue to evolve to support microservices, containers, and multi-cloud portability.

Organized by the Jakarta EE Working Group, the survey was conducted over three weeks in March 2019. Just like last year (see the 2018 results here), Jakarta EE member companies promoted the survey in partnership with the London Java Community, Java User Groups, and other community stakeholders. Thank you to everyone who took the time to participate. Access the full findings of the survey here.

Some of the highlights from this year’s survey include:

  • The top three community priorities for Jakarta EE are: better support for microservices, native integration with Kubernetes (tied at 61 percent), followed by production quality reference implementations (37 percent). To move mission-critical Java EE applications and workloads to the cloud, developers will need specifications, tools, and products backed by a diverse vendor community. Jakarta EE Working Group members have committed to deliver multiple compatible implementations of the Jakarta EE 8 Platform when the Jakarta EE 8 specifications are released.
  • With a third of developers reporting they are currently building cloud native architectures and another 30 percent planning to within the next year, cloud native is critically important today and will continue to be so;
  • The number of Java applications running in the cloud is projected to substantially increase, with 32 percent of respondents expecting that they will be running nearly two-thirds of their Java applications in the cloud within the next two years;
  • Microservices dominates as the architecture approach to implementing Java in the cloud, according to 43 percent of respondents;
  • Spring/Spring Boot again leads as the framework chosen by most developers for building cloud native applications in Java;
  • Eclipse Microprofile’s adoption has surged, with usage growing from 13 percent in 2018 to 28 percent today;
  • Java continues to dominate when it comes to deploying applications in production environments. It comes as no surprise that most companies are committed to protecting their past strategic investments in Java.

Once again, thanks to everyone who completed the survey and to the community members for their help with the promotion.

Let me know what you think about this year’s survey findings. We are open to suggestions on how we can improve the survey in the future, so please feel free to share your feedback.

Frequently Asked Questions About Jakarta EE 8

I’d like to thank the community for the level of engagement we’ve seen in response to my post from last week.   This post, which again represents the consensus view of the Jakarta EE Steering Committee, answers some questions about Jakarta EE 8, which is planned as the initial release of Jakarta EE, and is intended to be fully compatible with Java EE 8, including use of the javax namespace.   We thought it would be useful to reiterate the messages we have been delivering about this release.

Note that this post is not about future Jakarta releases where the namespace will be changed. There is a vigorous discussion going on right now on the jakarta-platform-dev@eclipse.org list (archive), so if you are interested in that topic, I would suggest you participate there. We expect that it will be about a month before the Jakarta EE Spec Committee will determine the next steps in the Jakarta EE roadmap.

Will Jakarta EE 8 break existing Java EE applications that rely upon javax APIs?

No, Jakarta EE 8 will not break existing existing Java EE applications that rely upon javax APIs.   We expect Jakarta EE 8 to be completely compatible with Java EE 8. We expect Jakarta EE 8 to specify the same javax namespace, and the same javax APIs and the same behavior as is specified in Java EE 8.    We expect that implementations that pass the Java EE 8 TCKs will also pass the Jakarta EE 8 TCKs, because the Jakarta EE 8 TCKs will be based on the same sources as the Java EE 8 TCKs. Jakarta EE 8 will not require any changes to Java EE 8 applications or their use of javax APIs.

What will Jakarta EE 8 consist of?

The Jakarta EE 8 specifications will:

  • Be fully compatible with Java EE 8 specifications
  • Include the same APIs and Javadoc using the same javax namespace
  • Provide open source licensed Jakarta EE 8 TCKs that are based on, and fully compatible with, the Java EE 8 TCKs.
  • Include a Jakarta EE 8 Platform specification that will describe the same platform integration requirements as the Java EE 8 Platform specification.
  • Reference multiple compatible  implementations of the Jakarta EE 8 Platform when the Jakarta EE 8 specifications are released.
  • Provide a compatibility and branding process for demonstrating that implementations are Jakarta EE 8 compatible.

Will there be Jakarta EE 8 compatible implementations?

Yes.  Multiple compatible implementations of the Jakarta EE 8 Platform will be available when the Jakarta EE 8 specifications are released.  We expect that any Java EE 8 compatible implementation would also be Jakarta EE 8 compatible, and the vendors in the Jakarta EE Working Group intend to certify their Java EE 8 compatible implementations as Jakarta EE 8 compatible.  In addition, because the Jakarta EE TCKs are available under an open source license, we will “lower the bar” for other technology providers to demonstrate Jakarta EE compatibility for their implementations. The lower cost and more liberal Jakarta EE trademark licensing will allow more technology providers to leverage and strengthen the Jakarta EE brand in the Enterprise Java community.  Jakarta EE 8 will provide a new baseline for the evolution of the Jakarta EE technologies, under an open, vendor-neutral community-driven process.

What is the process for delivery of Jakarta EE 8

The process for delivery of Jakarta EE 8 specifications will be fully transparent and will follow the Jakarta EE Specification Process.  Expect to see in coming weeks the delivery of initial, draft Jakarta EE 8 component specifications corresponding to Java EE 8 component specifications.  These will contain Javadoc defining the relevant APIs, and TCKs for compatibility testing. To publish specification text, we need to acquire copyright licenses for this text.  We have obtained Oracle and IBM’s copyright licenses for their  contributions, and intend to obtain the remaining copyright licenses required to publish the text of the Jakarta EE 8 Platform specification, and as much as possible of the component specifications. If you contributed to the Java EE specifications at the JCP in the past, expect to be contacted by the Eclipse Foundation to provide a license to use your contributions in Jakarta EE going forward. Providing such a license will be an important step in supporting the new specification process and the Jakarta EE community.  You will see these draft specifications evolve to final specifications in an open community process. Join the specification projects and participate!

When will Jakarta EE 8 be delivered?

The Jakarta EE Working Group intends to release final Jakarta EE 8 specifications by the fall of 2019.    This is an open community-driven effort, so there will be transparency into the process of driving the Jakarta EE 8 specifications, delivery of the Jakarta EE 8 TCKs, and Jakarta EE 8 compatible implementations.

Update on Jakarta EE Rights to Java Trademarks

Summary of progress to date and implications of the agreement between Eclipse and Oracle on Jakarta EE and use of Java trademarks and the javax namespace.

Introduction

The migration of Java EE to the Eclipse Foundation has been an enormous effort on behalf of the Eclipse Foundation staff and the many contributors, committers, members, and stakeholders that are participating.

This post was reviewed and represents the consensus view of the Jakarta EE Steering Committee.

Earlier this year GlassFish 5.1 was certified at Eclipse using the Java EE 8 TCK at the Eclipse Foundation. Since then under the direction of the working group the community established a Jakarta EE Specification Process (JESP) for the evolution of the Jakarta EE specs at the Eclipse Foundation. Specification projects are being created for all of the Jakarta EE specifications. The TCK process is being refined for Jakarta EE in concert with the new Jakarta EE compatibility logo. This is all being done in support of the Jakarta EE 8 release.

Progress to Date

The Jakarta community has been busy.

  • Oracle contributed GlassFish and the Java EE APIs and TCKs to Jakarta EE.
  • The Jakarta EE Working Group was formed and supporting committees to provide governance to the community and facilitate collaboration.
  • Eclipse GlassFish was certified with the Java EE TCK at the Eclipse Foundation.
  • The Eclipse Foundation Specification Process was created, and customization created and approved for the Jakarta EE Specification Process.
  • Specification projects are being created and work is underway now within the community to deliver the Jakarta EE 8 release later this year.
  • There is an initiative underway for Oracle, IBM, Red Hat and other members of the JCP to contribute their specification documents created at the JCP to Jakarta.

It had been the mutual intention of the Eclipse Foundation and Oracle to agree to terms that would allow the evolution of the javax package namespace in Jakarta EE specifications.   Unfortunately, following many months of good-faith negotiations, the Eclipse Foundation and Oracle have been unable to agree on terms of an agreement for the Eclipse Foundation community to modify the javax package namespace or to use the Java trademarks currently used in Java EE specifications.   Instead, Eclipse and Oracle have agreed that the javax package namespace cannot be evolved by the Jakarta EE community. As well, Java trademarks such as the existing specification names cannot be used by Jakarta EE specifications.  Because of the complexity and confidential nature of our negotiations, the Eclipse Foundation and Oracle have also agreed that we will not attempt to characterize here what has resulted in this outcome. It is the best outcome we could mutually achieve for the community. Some additional context is provided in the Eclipse Foundation Board and Jakarta EE Steering Committee meeting minutes.

What restrictions does this outcome impose on the Eclipse community?

Oracle’s Java trademarks are the property of Oracle and the Eclipse Foundation has no rights to use them.   The implications of this are as follows:

  1. The javax package namespace may be used within Jakarta EE specifications but may be used “as is” only.  No modification to the javax package namespace is permitted within Jakarta EE component specifications. Jakarta EE specifications that continue to use the javax package namespace must remain TCK compatible with the corresponding Java EE specifications.
  2. Jakarta EE component specifications using the javax package namespace may be omitted entirely from future Jakarta EE Platform specifications.
  3. Specification names must be changed from a “Java EE” naming convention to a “Jakarta EE” naming convention.  This includes acronyms such as EJB, JPA or JAX-RS.

In addition to the above, any specifications which use the javax namespace will continue to carry the certification and container requirements which Java EE has had in the past. I.e., implementations which claim compliance with any version of the Jakarta EE specifications using the javax namespace must test on and distribute containers which embed certified Java SE implementations licensed by Oracle. These restrictions do not apply to Jakarta EE specifications which do not utilize javax, including future revisions of the platform specifications which eliminate javax.

Note that the ratified Jakarta EE specifications will be available under a different license (the Eclipse Foundation Specification License). This is the reason why the Eclipse Foundation is currently asking the community to update their contributor and committer agreements.

What is next for the Jakarta EE Working Group?

The Jakarta EE Working Group including Oracle will continue to do what they set out to do: namely, move Java EE to the Eclipse Foundation. The group remains committed to creating a Jakarta EE 8 specification, logoed under the Eclipse Foundation’s Jakarta trademark. Further, the group is also committed to future versions of the Jakarta EE specifications that deliver on the original promises of innovation and evolution in cloud-native Java.

What does it mean for Jakarta EE to not modify the javax package namespace?

The Agreement does allow for modification and evolution under a new namespace, such as jakarta. It is expected that all future evolution and innovation will not use the javax namespace.

What happens to the Jakarta EE brand?

The Jakarta EE compatibility and the Jakarta EE member logos have both been decided on by the community and published. Work is underway to deliver the branding usage guidelines and supporting trademark license agreement. We expect to see the usage of these brands later this year.

Will there be a Jakarta EE 8?

Yes. The community is working hard to deliver the Jakarta EE 8 release, which is Java EE 8 delivered from Eclipse. We expect that many application servers will certify as Jakarta EE 8 compatible.

What happens beyond Jakarta EE 8?

The guiding principle for Jakarta EE 9 will be to maximize compatibility with Jakarta EE 8 for future versions without stifling innovation.  This will most likely involve two key topics: migration of some or all of the Jakarta EE specification source to a new namespace for future evolution; means to provide backwards compatibility with javax at a binary level, allowing old applications to run on Jakarta 9 implementations with some form of build or runtime tooling.

So while there will be a point in time where future versions of specifications will have to go through a source code incompatible change with respect to the previous javax based packages, this will be a straightforward transformation.

Further plans are being evolved by the Jakarta EE community via the Jakarta EE Platform Project. Your comments and participation are encouraged.

What does this mean for the EE4J projects?

The specification projects need to be renamed to not use Oracle’s Java trademarks. The Jakarta community gets to decide on the new names. This is an opportunity to tighten up the naming and get a better level of consistency. The future of Eclipse Enterprise for Java (EE4J) projects will be determined by the community who participate in those specifications and open source projects.

What is next for Eclipse GlassFish?

Work is underway at the Eclipse GlassFish project running the Jakarta EE 8 TCK and being ready to support its role in the TCK for interop testing. The future of Eclipse GlassFish will be determined by the community who participate in the project.

How will specs be updated beyond Jakarta EE 8?

Jakarta EE specifications will be updated according to the approved Jakarta EE Specification Process (JESP). The actual enhancements will be determined by the community who participate in those specification projects.

New Eclipse Foundation Committer and Contributor Agreements

Note: to see redline versions of the changes to the documents discussed below, please visit this contribution and committer agreements page.

Over my almost 15 years of sharing updates about what’s going on at Eclipse, some blogs are more important than others.  This one is important as it requires action by our members, committers, and contributors!  There is a lot of ground to cover explaining what’s going on and why we’re changing things, so please forgive me for a longer than normal post.

tl;dr.  The Eclipse Foundation is starting to develop specifications. First for Jakarta EE, but soon for other areas as well. We want to make it clear that contributions to our open source projects may someday be used to create a specification, because we believe in code-first innovation. We also believe that if you’re contributing to open source, you want your contributions to be used for open purposes, including specs.

We are updating our standard contributor and committer agreements, and we will be requiring all our committers and contributors, as well as those members who have member committer agreements,  to re-sign their agreement with us.

To make this happen, we will be reaching out to everyone who needs to re-sign.  You don’t have to do anything yet – just be aware the change is coming, and please act when we do make contact with you.

First, a bit of background.  All contributions and commits made to any Eclipse Foundation project are covered by one of three distinct agreements – the Member Committer Agreement, the Individual Committer Agreement, or the Eclipse Contributor Agreement.

These agreements basically say that if you contribute to an Eclipse project, your contributions are being made under the license of the project. That license is usually the Eclipse Public License, but about 20% of our projects using additional or alternate licenses such as the Apache License, BSD, or MIT. It is important to note that the way things work at the Eclipse Foundation, the Foundation itself does not acquire any rights to the contributions. This is very different from other organizations like the FSF, OpenJDK, or the Apache Software Foundation. Eclipse uses a licensing model sometimes referred to as symmetrical inbound/outbound licensing, where contributors license their code directly to the users (recipients) of their contributions. Our approach requires us to ensure that all of our contribution agreements provide all necessary grants because we at the EF don’t have any rights to re-license contributions.

As most are aware, Eclipse is now about to start hosting specifications as open source projects.  This is very exciting for us, and we think it represents a new opportunity for creating innovative specifications using a vendor neutral process.  The first specification projects will be a part of the Jakarta EE initiative, but we expect other specification projects to follow shortly.

Everyone expected to re-sign one of these is encouraged to ensure they understand the details of the agreements and to seek their own legal advice. However, the change we have made is basically to ensure the copyrights in contributions to Eclipse projects may be used in specifications as well. (For the lawyers in the crowd, please note that these additional grants do not include patents.) We certainly expect that our committers and contributors are fine with this concept. In fact, I assume that most folks would have expected that this was already obvious when they contributed to an open source project. To that, all I can say is….ahhhh…the lawyers made us do it.

The new agreements are already posted, so they are in immediate effect for new contributors and committers. Since we need to overhaul our contribution agreements, we are also taking this opportunity to fix a few things. In particular, our committers will know that up until now they’ve been required to be covered by both a committer agreement and the ECA. We’re going to fix that, so if you sign an Individual Committer Agreement, or are covered by your employer’s Member Committer Agreement, you will no longer have to personally sign an ECA. We are also going to implementing electronic signatures for ICAs using HelloSign. So going forward there is going to be a little less paper involved in being a committer. Yay!

We’re sensitive that asking our contributors and committers to ‘update their paperwork’, especially if they’re not working on a specification, is – well, a pain in the backside.  But we’re hoping everyone will be supportive and understanding, and recognize that we take IP very seriously, and it’s one of the real value propositions of working with Eclipse.

Contributors who have an ECA will see them revoked over the coming months, and will be asked to re-sign the new one. We will be starting first with the contributors to the EE4J projects, since they are the ones who are most likely to have contributions flowing into Jakarta EE specifications.

Executing this change represents a massive effort for our team, as it literally means updating hundreds of committer agreements.  Our staff will be emailing individually each individual and member company needing to update their agreement with us, but we will be spread it over a period of the next few months.  So don’t be surprised if you don’t get an email for a while – we will get to everyone as soon as we can.

Stay tuned for emails on this subject that will be sent to our various mailing lists with more details.  If you have questions, feel free to reach out to us at license@eclipse.org and we’ll do our best to provide answers.

I thank our entire community in advance for accommodating this significant change.  We are excited about the Eclipse Foundation hosting an even more vibrant collection of projects, and believe hosting open source specification projects is a great step forward in our evolution!

Introducing the Jakarta EE Specification Process

I am very happy to announce that we are publishing a draft of the Eclipse Foundation Specification Process for community review and feedback. This specification process will be used by Jakarta EE as the new open specification process, replacing the JCP process previously used for Java EE. It is also expected that this new process will be of interest to other Eclipse working groups.

We are really looking forward to your feedback, which you can do via the Jakarta EE Community mailing list (preferred), or on the document comments.  The feedback provided will be used as input to finalizing a first version of the specification process and its adoption by Jakarta EE and other working groups at the Eclipse Foundation.  

As you are reviewing this draft specification process, please keep in mind the following key points about the approach that was taken by the Specification Committee.

  1. We want to design a specification process to replace the JCP. While there are many differences with the JCP, the key objective was to make the whole process as lightweight as possible.
  2. We want the specification process to be as close to open source development as possible. This is actually not a trivial exercise, as by its very nature drafting specifications is a somewhat different process.
  3. This is the Eclipse Spec Process, so we want to reuse the Eclipse Development Process wherever possible, and we want to ensure that the general flow and tone of the EDP is followed.
  4. We want to create a process that allows code-first development. Specifically, we want to enable a culture where experimentation can happen in open source and then have specifications be based on those experiences.
  5. We want the specifications that result from this process to be as high quality as possible. In particular, this means that we need to take care of the intellectual property flows, and to protect the community’s work from bad actors. This requirement manifests as two fundamentally important differences from the EDP:
    • Specification Committee approval is required for releases from Spec Projects, in addition to the normal PMC approval; and
    • We introduce the notion of “Participants” who are committers who represent specific member companies on a Spec Project. This is necessary to ensure that the IP contributions (particularly patents) from companies are properly captured by the process.

All of us at the Eclipse Foundation would like to recognize the tireless efforts of the members of the Specification Committee. A lot of hard work has gone into this document, and it’s very much appreciated. We are certain that Jakarta EE, and many other Eclipse technologies, benefit from the thoughtful efforts of this Committee.  In particular, we would like to thank the following Specification Committee members and alternates:

Fujitsu: Kenji Kazumura​, Mikel DeNicola
IBM: Dan Bandera​, Kevin Sutter
Oracle: Bill Shannon​, Ed Bratt​, Dmitry Kornilov
Payara: Steve Millidge​, Arjan Tijms
Red Hat: Scott Stark, Mark Little
Tomitribe: David Blevins​, Richard Monson-Haefel
PMC Representative: Ivar Grimstad
Elected Members: Alex Theedom, Werner Keil​

I also wish to recognize Tanja Obradovic and Wayne Beaton from the Eclipse Foundation team who have driven the process throughout – many thanks to you both!
