Parallel task execution in J2EE using the Work Manager specification by Dmitri Maximovich — As it stands, the J2EE specification provides no easy way to initiate the execution of parallel tasks. JSR 237, the Work Manager for Application Servers specification, changes this. In this article, Dmitri Maximovich introduces the specification, and provides an example of how to use it. His code runs on the current beta of WebLogic Server 9.0.
Jeryl, i agree with his article, however Quartz is a J2EE scheduler, you just have to use JDBCStoreTX instead of RAM, if used with a JMS queue..it makes it J2EE complainant.
somone flame me if im wrong, but we are using it.
