By the way ...
If that is your actual code .. I have a few suggestions.
1) Create a plug-in that, on initilization, stores the JNDI context into
either the Applciation or Session object.
- rather the create it every time.
2) Make use of the EJBHomeFactory pattern when gaining access to the EJB
Home interfaces.
- reduces calls and produces less redundant code.
3) Make use of a Session facade to hide all EJB activity.
- Centralizes a service layer that can be interchanged ( in case you
want to use your app with some other the EJB )
Any help you need with that ... I here for ya.
D.
Do you have an example struts-config.xml and jsp for that code below for me?
