Hi Wes,
I'm accessing the bean over a service locator. I have attached the class
source at the end.

How are you getting a copy of your EJB in your action?
vwg.yyy.cancard.ui.action.Usermanagement.Usermanagement.list(Userman
agement.java:41)
That line in the stacktrace indicates that you are in the action when
you get the error, but the stacktrace dives down into a proxied object
after that. You do realize that you can't use the standard @Remote /
@Local on struts 2 action properties? Struts 2 creates it's own
objects so any JEE annotations are probably not going to work.
