4.0 GA – JSP validation question

No luck. Either the new settings aren’t taking, or there would seem to be something wrong with the jars themselves. I do see the .classpath file updating, but no change in the editor. Even after many Eclipse restarts, -clean, project clean + rebuild, etc. I haven’t rebooted the system, but this isn’t Windows.

Ok, this is it. I symlinked /home to /home/jim/workspace/home so
/home/jim/workspace/home/jim/MyEclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_4.0.0/data/libraryset/1.4/
will exist. This now gets rid of my editor errors. This means that no matter what I tried to do in preferences and what .classpath said, the editor was always still looking for it’s libs there (in the wrong place). I have no idea what could cause that, but hope it helps in debugging.

Any news? I removed Eclipse, MyEclipse, /tmp/* and workspace. I then installed Eclipse clean, then MyEclipse (as my user). I loaded eclipse with -clean flag. Created a new MyEclipse web project and then a new MyEclipse JSP. Same errors:

Looking at package explorer, the libs are listed and have the correct path. Looking at Preferences/Java/Build Path/Classpath variables all MYECLIPSE_* variables have the correct path. Are we absolutely sure that there isn’t code in the Linux version that would prepend something to the path of libs in MyEclipse projects?

Unless there are hidden files that I don’t know about, this is as clean a setup and description as I can get.

Wonderland just gets more interesting. I switched to tempworkspace and created a stuff project. Everything worked fine. I then created a home project (because thats the name of the project I was originally working on). The JSP in home broke. Created a stuff2 project, its JSP was broken. Removed the home project, did a clean on all projects, and all JSPs in all other projects were happy again.

This problem seems to be related to having a project named home. Which was a problem for me, since I’m working on a project named home and always tried to create a project with that name. Bizarre to say the least, but it looks like as long as I stay away from home, things work much better.

I hope with that added info, this will be reproducible.
