Question

I have an EJB A that invokes EJB B. The UI should not wait for more than 30 seconds for a response. If some data is missing, it should return a partial response.

How can I define a timeout (time limit of 30 seconds) on EJB B?

I can define EJB B as Asynchronous that returns Future, and then do Future.get(30, TimeUnit.SECONDS).
But is it the best solution?

thank you

P.S. I use glassfish 3.1

Answer 1

To configure timeout for a bean which applies to all its methods, you have to configure the attribute cmt-timeout-in-seconds in glassfish-ejb-jar.xml.

This timeout value is used by all the methods of the bean that initiates a new transaction, not applicable when they join other ongoing transaction.

Also can refer this link for further details on timeout.
