I'm looking at the quickstart\helloworld_file_action that comes with JBossESB 4.5 GA and I noticed that the jms-message-filter can be specified in either the provider or the service elements. Why would I want to specify the filter in the provider vs the service?
If it really doesn't matter where I specify the filter then I don't see how the filter is working in this example. I see that "type='fromHelloworldFileAction'" has been added to the message, but I don't see who/what added it to the message. And, I'm not sure that anything is really filtered.
