JADE Web Service Consumer

The JADE Web service consumer enables you to access external Web services (including JADE Web services) from within a JADE application. A Web service consumer service cannot be called asynchronously from a JADE application.

Some of the highlights of the JADE Web service consumer feature are as follows.

• Use of a wizard to import Web Services Description Language (WSDL) from WSDL files or a Uniform Resource Identifier (URI)

  When a WSDL file is imported into JADE, a subclass of the JadeWebServiceConsumer class is created for each service that is defined in the WSDL.

• Setting up Simple Object Access Protocol (SOAP) message requests for the requested Web service method with the appropriate parameters

• Creating the required proxy objects based on the SOAP message response

• SOAP faults are converted to JADE exceptions

• Ability to handle RPC/Encoded, RPC/Literal, Document/Literal Bare, Document/Literal Wrapped, and Document/Encoded messages

• SOAP header support

• Abstraction of the messaging and transport layers

• Supports HTTP directly, but other protocols can also be used by method reimplementation
