Classloading problem

Hi Folks,
As you can see from the stack trace below I'm trying to run a lifecycle module which
(within a lib) tries to use its own classloader(InvocationMethodFactory$InvokeClassLoader which
extends from java.lang.ClassLoader) to define a class
(org/jruby/internal/runtime/methods/FullInvocationMethod) but fails.

I understand why it fails but am wondering what do to get past the issue ...
Is there a switch with which the jars/classes in $GLASSFISH_HOME/lib are loaded
via system(or is it bootstrap) classloader as opposed to glassfish's common classloader
so that java.lang.ClassLoader finds the missing class ? Or any other suggestions
to get past the issue ?

THanks
Ashish
