Description jlaskowski 2008-03-23 15:42:38 UTC

1/ Created a new visual web jsf project

(didn't restart NB)
3/ Created a new visual web jsf project with the same name as the one from 1/ => NPE's thrown:

Comment 1 _ potingwu 2008-03-23 19:21:02 UTC

Please see the release note:
    http://www.netbeans.org/community/releases/55/1/vwp-release-notes.html#knownissues 

    Clean and Build fails after application deployment.
      Description: Application deployment returns the error "Unable to delete file ...\build\web\WEB-INF\lib\appbase.jar".
      Workaround: Stop and restart the application server and deploy the application again.

You need to stop your server to delete your project. And the most important part is, when the project is still somehow
opened and cached in the IDE, manually delete its components from outside of IDE will cause fatal error. You should not
reply on this kind of action!

Comment 2 jlaskowski 2008-03-24 00:26:47 UTC

The issue is not about the exception itself, but how a user is informed about it. There should not be any stack traces
popped out. If it's a known issue just catch the exception is report it as ERROR in the log.

Comment 3 _ potingwu 2008-03-24 23:40:50 UTC

As I said, please see the release note:
    http://www.netbeans.org/community/releases/55/1/vwp-release-notes.html#knownissues

Comment 4 Karthikeyan Rajeswaran 2008-04-20 20:01:42 UTC

This issue is very likely a a duplicate of issue 130683 .
