Hi All, Thank you for your Suggestions. Since EJB Mediator also have some issues in working as Discussed in Yesterday meeting first i stared to get more domain knowledge and then i plan to start the development. EJB 3.X is light weighted and more features then EJB 2.X but since as malaka mentioned our clients are prefer EJB 2.X first connector will be for EJB 2.X.
