Hi,

I just moved from doing development on Linux to a Mac and installed Eclipse 3.3 and MyEclipse 6. The Java runtime is 1.5.0_13. I’m assuming that the missing classfile is this is a MyEclipse classfile. The error as reported is:

An internal error occurred during: “JSP Semantics Validator (JSF)”.
org/eclipse/wst/sse/ui/internal/reconcile/validator/ValidationHelper

The logfile shows the following:

!ENTRY org.eclipse.core.jobs 4 2 2008-06-08 13:59:21.732
!MESSAGE An internal error occurred during: “JSP Semantics Validator (JSF)”.

How do I fix this?

Thanks,

Rob,
Did you use the Eclipse 3.3 classic version with MyEclipse 6?

Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Did you use the Eclipse 3.3 classic version with MyEclipse 6?

When do you get this error?

[Rob Tanner]

Looking back at the downloads page for Eclipse, I see that I downloaded both the IDE for Java EE Developers and Eclipse Classic 3.3.2 versions, but I actually installed the former. On my Linux environment (which does not have the problem), I’m not sure which variety of Eclipse I’m running.

As for when it shows up, so far I’ve discovered the problem whenever I open a JSP and also whenever I save a modified file, JSP or classfile.

Should I redo the install but this time use the classic version?

Should I redo the install but this time use the classic version?

Yes. You will have to reinstall MyEclipse with Eclipse classic.

[Rob Tanner]

That fixed it. Thanks.
