1.5M2 JSP Compilation Support ClassCastException

[gadams00]

I've got the following installed on Windows XP:

Eclipse-SDK-3.1-win32
emf-sdo-xsd-SDK-I200506230200
GEF-SDK-3.1RC4
VE-runtime-I20050623
JBossIDE-1.5M2-ALL

When I enable JSP compilation support on a project, I get the following in my error logs:

Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".

java.lang.ClassCastException: org.eclipse.core.runtime.internal.adaptor.ContextFinder

If I purposefully introduce a syntax error in my jsp, I get no problems in the problems tab (i.e. JSP compilation is not occurring).

Is anyone else experiencing this problem?

Thanks for you help, and the integration with Eclipse 3.1 Final is great.

update... I actually do see problems with the JSP files being shown in the problems tab, I just hadn't re-saved any of the jsp files since getting the exception.

have you found solution?

I'm not able to compile any JSP.

1. I can't check to enable the JSP compilation - it throws an error.
2. even I get this check box is checked - Eclipse doesn't compile JSP anyway.

[gadams00]

Nope, no solution for me. I've asked for a JIRA issue to be opened in this forum in another thread. I've downgraded back to Eclipse 3.1M4 and JBoss IDE 1.4.

I was, however, able to get the JSP compilation setting to turn off with some manual tweaking. I edited the .project file and removed the entries that pertained to JSP compilation ( I think there was a builder entry and a nature entry or something like that, but I can't really remember). Then I had to remove my .metadata directory in my project root, and run eclipse -clean, then reconfigure all my windows->preferences settings (jdk 1.5.0_04, code level 5.0, etc) and re-import my project, and everything except JSP compilation works again - I was then able to open the JSP editor, which was impossible with the stuck JSP compilation support setting.

[mikek753]

looks like that is JSP builder issue - incorrect class or etc.

Without JSP compilation - I can't do much with M2 for a while.

Most likely I'll downgrade too to get JSP support works.

I've opened a JIRA issue for this problem:

http://jira.jboss.com/jira/browse/JBIDE-209

cool
lets hope that would be addressed ;-)

[mikek753]

any new for that matter?
any plans to put back JSP compilation support? and what time frame?
does it depend from WTP to be released first?

thanks.

Mum's the word. They did state they are putting much of the WebTools package in for the final 1.5 release, but as of now there is no support at all for JSP compilation. I have to precompile via a regular ant script elsewhere and import the resulting java classes into my project
