We have a Stateless Session Bean that REQUIRES a new transaction for each of its methods. The session bean passes off work to several delegate objects that are also given a reference to the inject Entity Manager. These delegates do an em.flush to update the database (informix 9.4 with Datadirect type 4 drivers). This seems to result in rows showing up in the database that aren't committed and therefore would need to be read with a DirtyRead. ** 1 : how can the EM be setup to do dirty reads? ** 2 : the session bean methods are logical business methods and thus one transaction; however, it would be desireable to actually do sub transactions within them. How can this be done? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983064#...
