I am running the rpcrouter servlet under weblogic 6.1. My classpath has xerces.jar first (v 1.4.0), followed by soap.jar (v 2.2), followed by weblogic.jar. When I run the ServiceManagerClient utility to deploy my services, I get the following error: SOAP-ENV: Client Unable to resolve namespace URI for 'ns2' Does anyone know why this would be happening? I just upgraded from weblogic 5.1 and did not have this problem with that version. Thanks, Ed
