The SOAP provider allows WSIF stubs and dynamic clients to invoke SOAP services.
Why and when to perform this task
The Web Services Invocation Framework (WSIF) SOAP provider supports SOAP 1.1 over HTTP.
The
SOAP provider uses Apache SOAP 2.3 for parsing and creating SOAP messages,
but it is not limited to invoking services from Apache SOAP.
The
SOAP provider is JSR 101/109 compliant and uses Web Services for J2EE for
parsing and creating SOAP messages.
Note: The current WSIF default SOAP provider (the IBM Web Service SOAP provider) does not fully interoperate with services that are running on the former (Apache SOAP) provider. This restriction is due to the fact that the IBM Web Service SOAP provider is designed to interoperate fully with a JAX-RPC compliant Web service, and Apache SOAP cannot provide such a service. For more information see WSIF SOAP provider: working with legacy applications.
The SOAP provider supports:
The SOAP provider is not transactional.
The SOAP provider does not support the WSIF synchronous timeout. The SOAP provider uses the default client timeout value that is set for Web Services for J2EE.
If you have a Web service that you expect multiple clients to use connecting over SOAP, then before you deploy the service you must set up your application deployment descriptor file dds.xml to handle multiple connections correctly. For more information, see WSIF troubleshooting tips.
