WebSphere® ESB provides Message Service clients for C/C++ and .NET that enable non-Java applications to connect to the enterprise service bus.
Message Service Clients for C/C++ and .NET provide an API called XMS that has the same set of interfaces as the Java™ Message Service (JMS) API. Message Service Client for C/C++ contains two implementations of XMS, one for use by C applications and another for use by C++ applications. Message Service Client for .NET contains a fully managed implementation of XMS, which can be used by any .NET compliant language.
You can also install and use the J2EE client support from WebSphere Application Server, including Web services Client, EJB Client, and JMS Client. For information about installing J2EE client support, see Installing Application Client for WebSphere Application Server.
