Title: Contributing new JEE project facets

Hello,

 

Please take a look at bug 149007 [1]. This bug was created to track the progress of making JEE 5 support possible in WTP 1.5.1.

For the last few weeks there are some patches submitted as feature requests. They were reviewed by PMC members and components leads.

After short discussion it was decided that we change the focus for these changes to the 2.0 stream and we (SAP) work closer with the WTP team.

One suggestion was that we provided JUnit test suite to help proving the quality of the changes.

 

I have had a look at some documents regarding Automated testing and the org.eclipse.jst.j2ee.core.tests and org.eclipse.jst.j2ee.tests plugins.

I noticed something strange. Let's take the org.eclipse.jst.j2ee.core.tests plugin. There are ~1300 tests defined there, but only ~300 are executed on the central test system [2]. Why is this? What about the other ~1000 tests?

 

Another question is where can I see something like method coverage of the current tests?

 

Can we have also some guidelines in which direction to improve the test cases?

Execuse me for these untidy questions, but we have to somehow get more oriented how we can work together with you in the best way to contribute the JEE 5 support.

Any guidance by you would be helpful.

 

Greetings

Subject: [wtp-pmc] Contributing new JEE project facets

Hello,

SAP adopts the Eclipse platform in the SAP Netweaver platform. The next major release of the SAP Netweaver will be based on WTP 1.5. One of the critical requirements is JEE 5 support. Since WTP does not have JEE 5 support for the 1.5 release, we have to implement this feature ourselves.

The natural approach that we want to follow is to extend the j2ee project facets with new versions (ejb 3.0, web 2.5, etc.) in plugins outside WTP. The project facets framework provides enough functionality to implement this. But we face problems with the current implementation of the j2ee plugins. There are lots of hardcoded version checks (project facet versions) inside WTP code. This prevents new versions of the j2ee project facets to work correctly, because they cannot extends certain program logic inside WTP. One possible solution for this problem is to define new extension points in the j2ee plugins that remove the hardcoded logic and deliver extensibility mechanisms.

So, the problem we face with extending WTP 1.5 in the JEE 5 domain can be separate in two main tasks:

1) Define new extension points inside WTP code to replace hardcoded logic.
2) Define new j2ee project facet versions and make them use the new extension points (defined in 1) to implement properly the new program logic. This can be done in plugins outside WTP.

We can provide the necessary development resources for implementing the two tasks along with the extensions supporting the current functionality. We would like to contribute the changes to WTP. We want to target the changes of Task No.1 for the 1.5.1 release. For Task No.2 we do not have strict requirements. If there is interest we can contribute the changes  for 1.5.1 or later versions.

We are aware of the 1.5.1 change policy. We can send the changes as independent backward-compatible patches that can be integrated with the code after PMC approval. All patches will be requested as hot bugs.

The main benefit of the suggested changes is that vendors will be more indepenent from the WTP schedule when supporting critical features regarding new J2EE specification versions. Moreover, this will reduce WTP's effort to adopt JEE 5 and future specification requirements.

I want to request the PMC members to evaluate our proposal and give their opinion.
