The Web service handler invokes Web services as an action.
The Web service is initiated through fields defined in the Web service template. These fields relate to a typical Web Services Description Language (WSDL) file used by Web services. A Web service template contains the parameters for a Web service invocation. Only Web services that take a Common Base Event as an input message can be supported. Business Process Execution Language (BPEL) processes are supported through the Web service handler. The BPEL process must be exposed through a WSDL file definition.
The Web service can be invoked asynchronously or synchronously depending upon whether the user needs a response from the web service.
