Hi, I think this is a very simple issue but I am getting confused.
I have a form in a web application which displays data and the user edits them. I use optimistic locking using the version lock strategy which seems to work fine as the version_lock column increments after each commit. I have a stateless session bean with a method that retrieves the value object (CMP Entity Bean) and populates the form. Then another method in the session bean does the update after the user clicks save changes. Both methods and the entity bean are marked as Required in the ejb-jar.xml My problem is that these two methods are 2 different transactions so JBoss does not detect the update of the data when 2 users update the form concurrently and no exception from the optimistic locking mechanism is thrown. The only way I can think is with client-initiated transaction which begins before the retrieval of the data and commits after the user clicks save. Is there a better way to implement this using XML declarations? I just need to include the user input (thinking time) inside the transaction.
