I like to continue this discussion. Currently I am using WebLogic as an EJB server.
WebLogic does provide JMS. I am thankful for that.
I am still vague about how JMS is a replacement for threads in EJB.
Here is a question I have.
I want a producer to post a message to a queue. I want this message to be picked up
asynchronously.
In order to accomplish this I want to wait inside a method .
I want this wait() method to be invoked with a Bean (mostly a session bean).
According to the Java specification this wait() must be inside a synchronized block
(no compile time errors but a IllegalMonitorStateException will be thrown at
run-time). Is this a violation of the EJB specification since I am using the keyword
"synchronized" within my EJB class.
I am having the SessionBean class implement the MessageListener interface.
Therefore it will implement the onMessage(String msg) method. This onMessage will be
invoked by another Thread-call back thread.
Ashwin.
