Try changing caught("java.lang.Exception") to caught("java.lang.Error") or
caught("java.lang.Throwable") and that should work. In any case if your
sure your dealing with
main::java::lang::NoClassDefFoundError=HASH(0xa594ec),
you can just try [EMAIL PROTECTED]>getMessage()
(In this case $@ contains a "reference" to the actual java.lang.Throwable
object (in your case java.lang.NoClassDefFound) that was thrown by Java)
Cheers,
Patrick
