User Comments:
cinhtau: I click "Click Create Persistence Unit" as I read this  http://netbeans.org/kb/docs/javaee/javaee-gettingstarted.html 

I have the current jdk1.6_017 installed and GlassfishV3.

GUEST: The following exception was thrown when invoking the wizard 'create entities from a db'. No screen was even shown.

GUEST: I tried to create new entity class from database

Comment 2 cinhtau 2009-12-24 13:22:32 UTC 
As I told before in http://statistics.netbeans.org/analytics/exception.do?id=321594:

I add a new datasource in ConnectionPools Glassfish Configuration and pressing the button Create Persistence Unit started to work. The cause is unknown to me.
Comment 3 cinhtau 2009-12-25 02:23:21 UTC 
I assume this is an unchecked verification. You are expecting a DataSource. This hasn't exists before. As I created a DataSource for my Postgresql-DB the NullPointerException didn't occur anymore. In general it is ugly not to verify if existing Objects->DataSources exists.
