Starting threads in EJBs

Enterprise Java Bean (EJB) specs forbids EJB components from managing (starting, stopping, suspending, resuming, changing thread priority, changing name) threads.

According to Wayne Beaton, if you must use a thread inside an EJB, take a look at JSR 237 which defines Work Manager. It's not currently part of the J2EE specification, but it is supported by both BEA and IBM in their application server products.
