sopa exception

Hi,
I am using SOAP-2_3_1 with JRun3.1 and Xerces1.3,
When I try to deploy the sample service urn:AddressFetcher using the ServiceManagerClient, I get the following error:
java org.apache.soap.server.ServiceManagerClient \
http://localhost:9000/soap/servlet/rpcrouter deploy DeploymentDescriptor.xml
Ouch, the call failed:
Fault Code = SOAP-ENV:Server.Exception:
Fault String = java.lang.NoSuchMethodError
I almost end up getting the above error for anything I do with servlet/rpcrouter in Lieu with sample applications. I could deploy same service using the soap application deployed on the admin server(I had porblem deploying on the default server).
Any pointer would be appreciated.

After digging into the docs for soap I found that I need a namespace aware parser and xercer1.3.1 is certainly not (after trying the testjsp page provided by http://ws.apache.org/soap/faq/faq_chawke.html#Q1_2). Could someone point me to the site for downloading xerces parser that is name space aware, I tired Xerces1.4.1 but the problem persists. Or, is there any setting tha tI am missing to make the parser NameSpace aware?
