getHibernateTemplate().load returning NullPointerException

[DistillingSpring]

I have the following:

service class:

...
PaymentPK paymentPk  = new PaymentPK(getId1(), getId2);// This is working fine and returning the correct values

Payment payment  = paymentDao.getPayment(paymentPk);//As in the Hibernate in Action examples, pg. 335
...

Dao implementation class:

....
	public Payment getPayment(PaymentPK id) {
		return (Payment)this.getHibernateTemplate().load(Payment.class, id);	
	}     	    		        	    		
...

I almost sure that I shouldn't receive a class as a parameter, but I have been following the example of the book and also did some researches but I didn't find other way out to send the parameters. Thanks.

NPE being thrown at that line means only that hibernateTemplate is null. Check your configuration file, to see if hibernateTemplate is properly injected, if using dependency injection.

It's working perfect for something like this:

getHibernateTemplate().find("from Payment p order by p.id")

So, the problem is with the composite id. Can I receive I class like I did?

Just a second.. let me double-check it.

You are alright! The find was in other test. In the class that is generating NPE, HibernateTemplate is null. I will try fix it. Thanks.

So simple, I fixed it and all is working nicely now! Thanks.

Just out of interest, what class were you extending. If you were using HibernateDaoSupport, an exception should have been thrown if either a sessionFactory or hibernateTemplate wasn't injected.
