Hi,
There was a race in XAManagedConnectionFactory.getXADataSource that
I've temporary fixed by synchronizing calls to this method. To
provide a better (faster) implementation I need to initialize
XADatasource when XAManagedConnectionFactory gets started but I
cannot find appropriate callback in
BaseWrapperManagedConnectionFactory class hierarchy. Am I missing
something?
I'm not sure what you expect to find. There aren't any lifecycle
methods in ManagedConnectionFactory, so you pretty much have to
initialize it when you first use it. I'm not sure initializing in a
start method would remove the need for synchronization anyway. (In
jca 1.5 there is a ResourceAdapter class with a start method)
Thank you, David.
Actually, I have found that XAManagedConnectionFactory implements
javax.resource.spi.ManagedConnectionFactory thus I could implement
createManagedConnection(...) methods to performs initialization.
I meant createConnectionFactory
However, I also realized that getXADataSource is called only a few times
(thanks for XAConnection cache), so there is no real point trying to
optimize it.
