Suspend a method execution inside J2EE container

Question

Hi,
I'm implementing a method that sends and resends payment transactions. The method resides in POJO java class and is going to be called from a Session EJB. When the same transaction has to be resent (accoring to some rules), we have to wait several milliseconds before doing it.
I know that threading should not be used directly inside a J2EE container, so what would be the way to implement the waiting before resending a transaction?
Thank you very much.

Yes, I have used java.util.concurrent.Executor in weblogic 10 server.
You can really improve the performance of the EJB application if you use the thread pool carefully with limited size say 100 threads, by creating a single instance of thread pool for the whole J2EE application.
You have to control the life cycle of thread pool using the container's life cycle methods, create the thread pool only once and destroy every time you recycle your app.
Good luck with the implementation :)
