INTERACTIVE WEB SERVICES WITH JAVA

WSDL - Web Service Description Language

• which interactions does the service provide?
• which arguments and results are involved in the interactions?
• which network addresses are used to locate the service?
• which communication protocol should be used?
• which data formats are the messages represented in?

• an interface description is a contract between the server developers and the client developers
• having formal descriptions allows tool support, e.g. code template generators
  (see the Apache AXIS project, the alphaWorks Emerging Technologies Toolkit, and CapeClear's WSDL tools)

The Cover Pages collects information about WSDL.

WSDL 1.2 is under development.
