Primefaces- JEE fails retrieving data

[Mark Resh]

I'm using the Primefaces JEE target which will create the menu and supposedly data classes to retrieve table data.  The project I am testing now has the menu working but when you click the table name I get the following error:

Unfortunately, there was an error processing you request

The error message is:    <no message is displayed here>

The tomcat logs below show the following, Which seems to point to an error on Pm2LazyDataModel statement 99  which is

				getService().find(data);

so we have another error to find and fix, any help would be appreciated.

Hello Mark,

I think it comes the fact that Tomcat is not a full JEE server.

The service is probably null.

It is passed by the controller as an arg in the constructor.

And in the controller it is injected (@EJB).

Unfortunately I do not think CDI is fully working in tomcat distrib.

It is better to test on glassfish / tomEE.

If you want to work with tomcat you can use Primefaces-Spring instead of Primefaces-JEE.

Best regards,

Florian.

Yes, I realized that I was not using TomEE,  I switched over to TomEE Plus but still get an error, so I tried the Primefaces Spring and built the pm2App.war for use on Tomcat 7.  However I get another error, see the error below.
