server deserializer problem - I've read the FAQ and archives

Server deserializer problem.

Hi all,

I have read through the examples and FAQ regarding
"How do I send user defined java objects using SOAP?"
and am still encountering a deserializer problem on
the server. The faultString: "No Deserializer found
to deserialize a 'urn://org.mitre.mii:foo' using
encoding style
'http://schemas.xmlsoap.org/soap/encoding/'"

I am running Tomcat 4.0.1.
Web Application 1 is the SOAP server called pdc_soap.war
Web Application 2 is called pdc.war

My client application makes a SOAP RPC to the SOAP
server running in Web App 1. The RPC invokes a method
on a Java object running in Web App 2.

I have created a very simple test RPC that has Web App 1
making a call to an object on Web App 2. It expects a
String as a parameter and returns a String result.
This works so I am assuming that my SOAP/Tomcat
installation is correct?

Any thoughts as to what is causing this faultString?
I have reviewed the deployment descriptor and
SOAPMappingRegistry and can't see any obvious errors.

Any help would be great.

-thanks
