Describe how to manage namespaces included in a SOAP message using SAAJ

Module 7 - Web Services Description Language (WSDL)


Describe the role that an interface description language (IDL) plays in a distributed computing environment
Describe the role that WSDL plays in the web service model and the primary elements contained in a WSDL file
Describe the role of extensibility elements used in a WSDL file
Compare the use of WSDL in document-style and remote procedure call (RPC)-style services

Module 8 - The Service Registry


Describe the purpose of a service registry
Define the two types of service registries
