*bump*
I don't mind doing some more legwork, but I could really use a nudge in the right direction. Aaron mentioned that I could use the console code as a template for what I'm doing. Can someone point me at the right place to look in the source tree? I did a little bit of poking around, but I got a bit lost trying to figure out which module to begin searching.
I think we already discussed that you are not going to be able to look up these datasources from jndi, so you'll have to provide your own access method.
I think what I would do is simply construct instances of the objects you need in code, and not even use gbeans for them at all. Something like:
TransactionSupport transactionSupport = new XATransactions(.... figure out what you want ...); PoolingSupport poolingSupport = new SinglePool(... likewise); ConnectionTracker connectionTracker = //look this up in the kernel or if this code is in a gbean use a reference TransactionContextManager transactionContextManager = //likewise
GenericConnectionManager cm = new GenericConnectionManager(transactionSupport, poolingSupport, true, connectionTracker, transactionContextManager, name, classLoader);
cm.doStart();//this doesn't actually do anything, but you should shut it down when you are done.
ManagedConnectionFactoryWrapper mcfw = new ManagedConnectionFactoryWrapper(mcfClass, DataSource.class.getName(), new String[] {}, datasourceImplClass, //this would be the tranql adapter datasource class if you are using tranql. You can get it from the ra.xml Connection.class.getName(), null, cm, kernel, abstractName, /I don't think this is needed if you don't serialize datasources. objectName, //I don't think this is needed. classLoader);
mcfw.doStart();
DataSource ds = (DataSource) mcfw.$getResource();
Hope this gives you some ideas on one possible way forward,
