I'm currently having this same issue on a project I haven't touched in months.  I haven't changed wonder, nothing changed in the class path.  There's no obvious reason what's going on, and overriding _sessionClass doesn't fix the problem, cleaning the project didn't help, restarting the computer didn't help, deleting the run configurations didn't help.

What Profiler settings did you change?

Changing compiler settings back and forth seemed to clean it up. Thanks.

not sure what changed in your app, but it's basically just guessing wrong on the session class .. you can override _session() in your WOApplication subclass and return the exact class you expect it to be.

if I put the following method in my Application

@Override
protected Class _sessionClass() {
return com.educlab.iep.Session.class;
}

I receive the following exception: 

Application: SaisieIEP
Error: java.lang.IllegalStateException exception
Reason:
java.lang.IllegalStateException: An Exception occurred while generating the Exception page 'WOExceptionPage'. This is most likely due to an error in 'WOExceptionPage' itself or WebObjects encountered an uncaught exception while creating a Session object.


Below are the logs of the original Exception which occured in com.educlab.iep.Application, then the later Exception in WOExceptionPage.
