[jboss-user] [EJB 3.0] - ClassCastException: EJB3 CMP using EJB QL. Client using Stat

Saturday, 8 March 2008

Hi folks.
I've got a weird ClassCastException occurring in my code
Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to
java.lang.Long...
It happens with an event listener for stateChanged on a JCheckbox
It calls into a method defined with ab int via an interface.
Can't figure out why this is doing this as I think its some sort of error in a
generated proxy.
Can someone shed some light for me:
Here is code:
