Spring-app on WAS Server in Debug mode problem
I have pretty simple Spring-based web application, having Hibernate as DAO implementation.
When I deploy this simple application and run my WAS server in normal mode, everything goes well (no exceptions on start-up logs).
Simple Controller successfully executes single method, which invoke BusinessServices, which calls Hibernate DAO class to load simple entity from database.
But, when I'm trying to debug my application (i.e. run WAS in debug mode, attach to it and set breakpoint in simple Controller) I got the following exception:

--------------------------------
Should I perform any specific steps to configure my WAS server to propertly run in debug mode with Spring-based applications?
