Hi ,
I faced a NPE when i try to use CodebehindUnknownHandler below are the full
stack trace for this exception , and after i spend some time investigating for
the cause of this error it turned to me that I defined
[code]struts.codebehind.defaultPackage=babPackage[/code] with incorrect package
name after I fixed the package name error it works fine but I think the
exception was miss leading.
