I've now checked in my jca 1.5 work. To see how the Work interfaces can be used as a thread pool not from an adapter, look at org.jboss.test.jca.inflow.BootstrapContextTest. This is an mbean that uses a thread pool. The thread pool itself is accessible from another mbean, BootstrapContext. You can deploy as many of these as you want.
The thread pool provides: --immediate excution (in the calling thread) --starting work, return when work starts executing (in separate thread) --scheduling work, return immediately. Each option can be "blind" or you can supply a transaction context to import and a listener to find out about the progress of the work. The spec includes a way for the app server to hint that the work is taking too long and should stop soon, but I didn't implement that. So far I'm not sure how useful it will be. Unfortunately the spec committee did not see fit to include a way to import a security context, just a tx context. Presumably we can get around this by defining a JBossExecutionContext that also includes a Subject.
