hi to all,

I’m a junior JPA programmer and a Netbeans short experienced user (but senior developper) I have the following problem using JPA’s wizards:

I have just installed Netbeans version 6.7.1


I have created a New project using 'Java J2EE' EJB module
I choose the default  option every time.
Then I add entities from database choosing "jdbc/sample" for connection, sample database and all classes, package : com.test.
Next I create a Persistant Unit (using default).
Before registering entities and choosing default options
Then, I create JPAController and choose all classes choosing default values
I create a new Java Class: and again default values, except for the package name using the same as above and I just to follow recommandations.
here is the code :
---
public class NewClass {

    public static void main(String p_arg[]){
    CustomerJpaController C=new CustomerJpaController();
    System.out.println("Test"+ C.getCustomerCount());
    }
}
---
Running this classe : I get the following error 
---
init:
deps-jar:
compile-single:
run-main:
Exception in thread "main" java.lang.NullPointerException
        at com.test.CustomerJpaController.getEntityManager(CustomerJpaController.java:34)
        at com.test.CustomerJpaController.getCustomerCount(CustomerJpaController.java:239)
        at com.test.NewClass.main(NewClass.java:15)
Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)

---
and the JPAController function getEntityManager return allways null !!!

I have used all wizards, and it does not work properly. (Same on PC Vista, Linux ...)
I hope this help.

Halicorne.
