Hi,

The web client works fine, and the app-client launches properly. But if I try to use any button (view customer information, for example)- I get the following error:

13:36:03,636 ERROR [SecurityInterceptor] Error in Security Interceptor

I am guessing it's silent login failure during launch and only manifests itself when I try to use it. I am using Jboss 5.1 in windows vista. Thanks in advance.
