The request handler is an OC4J Web Services-specific servlet, and runs as part of a deployed Web service. Key features of the SOAP request handler include:
 
Support for cookies and sessions for stateful Web services
Serializing and deserializing SOAP from XML
Support Document and RPC invocation styles
Management of a Web service’s lifecycle
