Hi,

i have more entity beans that must leave their messages on a queue and i
have more message-driven beans that must read the messages on the queue.
can i implement this situations?
how?
maybe i must use a topic instead of the queue, but can differets entity
beans leave their messages in the same queue or topic?

thanks and sorry for my english...

Not sure I fully understand your question, but it sounds like an example
of the producer-consumer problem which is typically demonstrated in most
textbooks on multithreading. See for example
http://java.sun.com/docs/books/tutorial/essential/threads/synchronization.html

Does this solve your problem?

One alternative worth considering is Jini (http://www.jini.org).
The JavaSpace service, in particular, is well suited to your
requirements.
