RE: Cannot deploy using Eclipse plugin. Jar file May be locked by another process

I must be doing something wrong.

I did some tests. I have created a simple ear application with only one jar file in the lib directory. And a simple web app.
The jar only contains a simple class with a String member. The class is not even used by the web app. And I am still having this
lock file issue.
So it can not be that the jar contains a class which would not close an handle.
I have also validated that the process locking the file is java.exe.

The process which lock the files is the server, not Eclipse or the plugin.
It is usually related to external frameworks that keep files locked (no
cleaning at undeploy time), not GlassFish itself.
