I get a NullPointerException in the .metadata/.log file when I try to deploy my Enterprise Application Project “pafeui_ear” from the Project Deployments dialog. In the GUI I only see an “Error” popup window. The EA project only contains the web-project “pafeui”. The problems started when I checked out the same web-project, from a different branch, over the existing web-project (“overwrite”).

I have tried to start with “eclipse -clean”, but it didn’t solve the problem.
I get the same error when I try to run with MyEclipse version 5.1.1 instead.

Version: 5.5.0 Milestone 2
Build id: 20070409-5.5.0-Milestone2

My ../.metadata/.log looks like this:

…

Joakim,
Because you checked one project out ontop of another, try and go to the EA project, right click on it and go down to MyEclipse and try and remove the web project module, hit OK, now go back and try and re-add the module.

[jaybis]

When I select “pafeui” in the “Module Projects” window, I get an empty “error popup window”, and after I have removed it I get another empty popup window. The .metadata/.log looks like this after this:

Sounds like something went wrong with the web project.

Can you check the .project file and tell me all the Natures listed in it? Also can you open your project properties for the Web File, and go to MyEclipse > Web and make sure that both text boxes have values filled in for them?

[jaybis]

Hi!

The file .project for the Web Project “pafeui” looks like this:

<?xml version=”1.0″ encoding=”UTF-8″?>

</projectDescription>

Can you describe more exact what you mean with “Also can you open your project properties for the Web File, and go to MyEclipse > Web and make sure that both text boxes have values filled in for them”.

[Riyad Kalla]

Sorry about that, can you right-click on your “pafeui” project, go down to Properties, then go to MyEclipse > Web, and you should see 2 text fields. What are the values in each one?

[jaybis]

Web-root folder: WebRoot
Web Context-root: /

[Riyad Kalla]

Shoot those look ok… so do your project settings.

Try this:
1) Remove the Web project module from the EAR and hit OK
2) Now rebuild/clean both projects
3) Restart MyEclipse
3) Now edit the EAR’s modules again and try and re-add the Web Module.

[jaybis]

That didn’t help. I get the same beaviour (with an “empty popup window”)I have tried both with version 5.1.1 and 5.5 M2. One strange thing is that I now can’t see any rows in the .metadata/.log file. The only diffenence from tuesday is that I have rebooted my computer.

I meet the error too:

help~! the 5.5.1GA + EC3.2.2 + wtp1.5.4

[beming]

Ok, I fixed now:

I delete the project, and new an new Web Project, copy all the src and file, refresh, add web capabilities and else what I need capabilities, and redeploy…
the problem fixed!!

[Loyal Water]

Glad to know you fixed it. Thanks for letting us know.

[Riyad Kalla]

jaybis,
As extreme as it seems, does aming’s solution work for you?

[jaybis]

Actually, I first thought it had something to do with that I have worked in the same workspace with both MyEclipse 5.1.1 and MyEclipse 5.5 M2. I experienced such a problem when we upgraded from Eclipse WTP 3.1 to 3.2. Then we neded to create a new workspace to get everything to work. The project(s) in my new workspace is now working! So maybe the lesson to learn from this is that you should not import a project from a CVS-branch over a project that was checked out from HEAD. I have also changed the name of the project to pafeui_branch, seems to be a better strategy.

Regards,
Joakim Tengstrand

[Riyad Kalla]

Joakim,
I’m glad to hear things are working better now.
