I don't believe there are any examples showing exactly what you are after.
Just include your stack trace and code inside back ticks - if you have specific problems and can't make that work post on the Seam Wiki forum.
You need to choose your dispatcher - Quartz
use at most one.
The seampay example uses the ThreadPoolDispatcher for tests only (a precedence of 40 is for tests).
With ... @Asynchronous and using quartz-dispatcher are you able to actually launch SLSB asynchrnously.
I have one and now that i converted it to a SLSB it no longer seems to run asyncrhonosuly.
