BEA and IBM Joint Specifications, anyone?
That summary probably gave away my bias. That I'd like to have my enterprise code initiate concurrent requests to disparate backend systems without relying on JMS. That I'd like to schedule tasks without doing anything illegal within a container. I am currently reading the 'Timer and Work Manager for Application Servers' specification. My only problem is that I cannot wait until WebSphere 6 or 7 comes out with these features. My problems exist today and I've had to use alternatives I don't particularly fancy.
See this and this from the CommonJ initiative.
