AFAIK, jsr88 support is not feature complete. If you look into the implementation it comes down to using the MainDeployer's deploy(URL)/undeploy(URL) methods for deploying modules that exist on the local filesystem.
Something that maybe interesting but I don't know how it could be made is to use jsr88 for managing jboss services. The problem here is that each service (mbean) has different configuration, in constrast to say ejb-jar.xml that has a fixed format.
So, I've experimented with a new DeploymentService
that primarily lets you create your own services.
There are a couple of missing features, like uploading a module or providing a synchronous(i.e. blocking) deploy/undeploy. The uploading will probably come from the remoting framework.
Maybe this could be used as a back-end to jsr88.
What has this got todo with JCA?
