I'm struggling with this issue for a good while now - I hope somebody can help me...

I want to develop a web service interface with methods that throw a custom exception. I have been using the developerWorks article on exception handling (http://www.ibm.com/developerworks/webservices/library/ws-tip-jaxrpc.html) and samples provided by web service toolkits like Axis as guides for my own implementation.

But JBoss (4.2.1.GA) keeps printing the following messages while deploying my WAR file:

19:25:26,031 WARN [JAXRPCMetaDataBuilder] Cannot obtain java type mapping for: {http://www.mycompany/MyService}>MyServiceFault
19:25:26,109 WARN [SchemaBindingBuilder] Type definition not found in schema: {http://www.mycompany.com/MyService}MyServiceFault
19:25:26,109 WARN [SchemaBindingBuilder] Cannot obtain type binding for: {http://www.mycompany.com/MyService}MyServiceFault
