In one of my session beans, I need to download contents from many different
URLs.  I have implemented a parallel downloader into which I can throw a
bunch of URLs, and it starts to download them on different threads.  When
the download of each URL is complete, it calls back on the supplied
interface to notify the client.

I need to use this component from an EJB.  What is the best way for me to
integrate it into my system?

I was thinking of wrapping it into an RMI server object which I can then
deploy into the JNDI namespace of the appserver, however, I am unsure of how
to best integrate with the "callback" mechanism.  I guess the callback could
simply call on the Session Bean, and pass the required information, however,
the process of re-acquiring (reloading) the state from the database is
expensive.

Are there better ways?  I am running under Weblogic 6.1 SP3, but don't want
to make my code Weblogic dependent.

Thanks for any insight you may offer.
