These are my today experiences (really my today headaches) porting a couple of applications from GlassFish v1 running with JDK5 to GlassFish v2 running with JDK6.
The applications was developed with NetBeans 5 and consist of a couple of EJB modules and a couple of web applications using the VisualWebPack in the NetBeans 5 (JSF).
First, I downloaded and installed JDK6 and GlassFish v2.
Before deploying the application you must take into account that my JDBC driver in GF1 (running JDK5) was a JDBC3 PostgreSQL driver. This driver is compiled for JDK5, thus I need to download and install (in the GF2 server) the JDBC4 version (not completed yet).
Next, I have created some database resources using the JDBC4 drivers. This works but generates a lot of warnings when application runs. To avoid them you need to put this option in your resources JDBC30DataSource=true.
Finally I have developed the applications. I this step I found strange behaviors and some server crashing problems. After trying 1000 thing I found that the problem was in a hyperlink in a JSF page. For an unknown reason, changing the hyperlink by a button (mantaining the same action) resolve the problem.
If you are working, like me, with PostgreSQL I would like to point this link about sequences:

Glassfish and PostgreSQL problems
If you are working with Glassfish v1_ur1_b14, PostgreSQL and NetBeans 5.5 probably you had experienced some dificulties with entity class.
(1) you develop the code.
(2) you compile and build your code (an .ear or .war file)
(3) you can't deploy your application :(, Glassfish says you there is an error (with a null desciption) but if you chech your app with the verifier utility it is right.
Well, here are acouple of links describing the problem (related with the @GeneratedValue annotation) and describing a solution:
