Can Publishing to a topic be done in a transaction?

[nsdeonia]

Hi All

This may seem to be a stupid question, but I have following situation.

I am working in a workflow product, which uses EJB in middle tier. We have a requirement to send notifications to other products by any messaging service. I have chosen JMS for that.
Now, My problem is I want to send a message whenever workflow advances. Suppose it is like follows...

mark activity 'a' as complete
send message 'a' is complete
start next activity(s)
send message for each of them....

Now I want that all four of above operations should be performed in a transaction... i.e. messages should only be sent if updating in database succeeds.

Can I do that in JMS & EJB?
Or I have to look for other alternatives instead of JMS.


Thanks in advance for any help

You do it in one method in a session EJB, wich calls your Entity EJB or does the database stuff, and then sends the massage with JMS using JMS RA. I do think there are examples for this in the testsuite, and in the free docu.
