Validator causes InvocationTargetException

[whafrog]

I have a validator called from an xhtml page. The app works fine when deployed on my local machine, but I get this error when I deploy the same .ear on our development server:

/school.xhtml @19,150 validator="#{schoolValidator.validateCode}": java.lang.reflect.InvocationTargetException

The method "validateCode" is actually run, since I can see the output in the log and no errors are generated. So it's accessible by the app.

The JVM, JBoss and SEAM versions are the same on my local machine and the dev server (though my local machine is WinXP, and the dev server is Linux). Any ideas why this would work on one machine and not another?

TIA, Jon

We need to see the stack trace - you may need to use a debugger to get that, or turn up logging.
