Mediation the Third

After my previous post about mediation in ESB, I should add that there is a third way to modify messages on the bus, that doesn’t go by the name of ‘mediation’: using a JAX-RPC handler. It’s only suitable for SOAP messages (which can be transported over HTTP or JMS), but is otherwise most similar to Platform Messaging mediations. The primary advantage of JAX-RPC handlers is that they are conformant to a JSR specification, but they aren’t able to do a number of things that mediations can, such as modify the target of a SOAP request.
