Runtime exception in initComponents() method

[vieraci]

This isn't really a "J2EE" question, I'm using NetBeans 6.1 SE to access a mysql database using the jdbc:mysql driver. This is the source code:

@SuppressWarnings("unchecked")
// <editor-fold defaultstate="collapsed" desc="Generated Code">
private void initComponents() {

em = java.beans.Beans.isDesignTime() ? null : javax.persistence.Persistence.createEntityManagerFactory("RM-PU").createEntityManager();

qry = java.beans.Beans.isDesignTime() ? null : ((javax.persistence.EntityManager)null).createQuery("SELECT e.Empl_id, e.Employee, e.access_lvl FROM empl_view e WHERE e.pwd = :user_pwd");

// App stops at the createQuery method above with this error:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

I've run into a brick wall here and don't know how to figure this out.
Can anyone please help ?

qry = .... ((javax.persistence.EntityManager)null)

Why null?
