One thing i would like to say while configuring the guvnor in the WAS 6.1 I
was getting the following errors after deployment. So, I commemted out the
JBoss seam and seam listener related lines from the web.xml. Is it causing
because of this? 
Also I think it's not configured with the repository properly. thanks for ur
reply. can u help me to resolve this problem....
