Looks like *I* need to read the JTA spec! I assume the XAResource
has callbacks so when the bean calls commit or rollback the connection
will be committed or rolled back?
But the main question is: Proxies. Looking at the DataSourceImpl,
I see that it doesn't actually return a connection, but instead a Proxy
for a connection. The proxies seem to be dynamically constructed bytecode
to wrap a specified class. That's pretty incredible (to me), but I'm not
really sure what it gets you. If I just use the existing DataSourceImpl,
I guess my connections would get wrapped in proxies too. If not, do I
need to manually wrap every connection in a proxy before I return it?
Why?
Thanks,
Aaron
