Hi Arun,

Here is a simple Hello World web Application using

JSPs/JSTL/simple Java Bean, JPA (Resource-Local Tx).

You will need to tweak the persistence.xml and the run property for the
project to point to your glassfish

To run
http://<host>:<port>/JPAWeb/


I will probably clean this up a bit more and push it as a blog later
this week.


FWIW, i did find it a bit painful to tweak the persisitence.xml in NB
5.5as i could not do anything but use a datasource because i was
configured to deploy to Glassfish. It should allow me to choose whether
I am using jta/datasource or a local resource without editing it by hand
(in the xml view).

Also, you might have to stop and restart your domain if you
deploy/undeploy as the build of v2 i had seemed to be a bit touchy to
constant redeployments.

Let me know if this is what you were looking for.
