Using Hibernate to access non-portal data via singleton

[bmcgovern]

I have a project where I have to create a portal along with a non-portal web app to allow different users to read and write to my secondary data set. Portlets will need to interact with this data as well as componants (jsps and servlets outside of the portal container. I would like to know if anyone has any recomendations on how to do this. My idea was to create a new local-tx-datasource in -ds.xml. But from there im not sure where to go. Ideally my goal would be to have hibernate bridge objects through some kind of singleton for both the webapp and ALL portlets to use. Is this possible? if so how?

Im on jboss 2.4 bundled portal and appserver.
'Thanks

Hi

Use mbean/xmbean, which is a singleton service available for JNDI lookup, as your business interface to model.

Thanks for the reply. I'm a jboss noob, sorry. Can you point me to some docs or explain some of the grittier details. Like what do i jar up .. where do i put it, stuff like that?

Here you go:

That explained Mbeans. But im still unclear, I think at a high level how it all fits together. I need to understand how both web apps and portlets can share a datasource, preferably through a hibernate session.

I've got my datasource set up and Im sure i can make calls on it through both a web app and a portlet but im unclear on the best approach for how to make my connections / how to set up hibernate for it. I'm just getting started and am confused.

It turned out rather easy. I followed this chapter and it worked first try.

thanks for the help everyone.
