Classloader problem: WAS 5 and Struts

[Max Tomlinson]

Hi -
We are having a problem loading a struts app on WAS 5:
It appears that the classloader doesn't like struts using the default applicationResource.property file via a getResoruceBundle:
Java2 security is enabled.
thank you,

OK, I have since learned that my problem must be due to security policy -- the inability for MessageResouces within struts to read the ApplicationResources.properties. I believe I need to set up a policy file?
Can someone please tell me how i do this?
thank you,

Is the struts library being loaded from the usual place?
It looks like one factor here is that the context classloader for the thread is not a "child" of the classloader of the struts package. See the API documentation for Thread.getContextClassLoader.
