SourceID1.2 and WSAD5.1 -Federation Error-

 Hello,

 I am a new SourceID.java user.
 I am trying to run the demo application using SourceID.Java 1.2 
and Websphere 5.1 . WSAD uses IBM JVM 1.4.1 , and I deploy sp and idp 
in two seperate machines.
 
 SP and IDP work fine in themselves, but when trying to federate
I get the error .
 For further information , see below.

1. go to SP and login
2. click on the "Click to Federate" link
3. redirected IdP and enter credentials
4. click on submit
5. EXCEPTION as stated below

An error occured. Replace this page (or the pointer in sourceid-sso.xml) with a "real" error page.
