My problem is quite strange, i thinking to create a EJB to monitoring my database connections, ´cause we believe there is a open connection somewhere. Ok, what i´m pretend to do is create a EJB with users´s login store inside and in every getConnection or closeConnection in my DAOs, i will use that EJB to check first if the connection is from the same user, second if there´s already a connection opened before ( ´cause usually we only use a connection per method in our DAOs ). The point here is, it must be very simple to do ( change only three places of code ( user´s login, connection´s creation and connection close ). How i could do that, is there a way to store a EJB like user´s session in WebApp? Regards, lottalava
