This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I am implementing my own JCA 1.5 resource adapter in JBoss 5.1. I have used Iron Jacamar to auto-generate corresponding skeleton code for JCA 1.5.
My question is, where/how do I actually return the connection to the connection pool?
From the end user's perspective, this would entail something like connect.close(), however I'm not sure where exactly in the JCA stuff I'm supposed to handle this. Somewhere in the the ManagedConnection I'm assuming? There are two functions destroy and cleanup however there is no implemention for them and they sound like they actually physically close the connection.
Also wouldn't I need to somehow call a function on the connection pool to let it know? This may be accomplished by triggering an event to a listener but again I'm not sure the details of implementing this or where it should occur.
I've never looked a connection pools from the other side of the fence. Perhaps if you looked at how JBoss AS does this for data sources, you could mimic that. I'm not sure where the exact source code is, but I would write a simple app that opened a datasource and printed out the full classpath for the class returned by JNDI when I look it up. The source for that class, and its close() method, should provide some clues.
