Hibernate get or load not raising HibernateException when record not found

I am trying to do:

        
        public static Tprogram findProgramByKey( Long key) throws DataAccessException
    	{
            Tprogram program = null;
    		try
    		{
    		   program = (Tprogram)HibernateSessionConfig.getCurrentSession().load(Tprogram.class, key);
    		}
    		catch( HibernateException e )
    		{
    			LOGGER.error( "Unable to find program for key = "+ key, e);
    			throw new DataAccessException( e);
    		}
    		return program;
    	}

Open in new window

I am deliberately passing a key that should result in a "not found", or something like that.
When I use get, program=null, when I use load, all program class variables are null.
Using Hibernate-2.1

The problem is, it does not throw ANY exception. As a hack I am now doing ...

    		if (program == null) {
    			LOGGER.error( "Unable to find program for key = "+ key);
    			throw new DataAccessException( "Program does not exist. " + key);
            }

Open in new window

and this works, however, I'm guessing there is a better way to do it.

The problem is, it does not throw ANY exception.

Well, i'm wondering why you were trying to catch one then? ;)

I can't speak with authority as i don't know that API, but not finding a datum would seldom be a reason for an exception

Well, I found the java doc and basically it says if the record is not found, null will be returned. So it's working just fine. http://docs.jboss.org/hibernate/orm/3.5/javadocs/org/hibernate/Session.html#get(java.lang.Class, java.io.Serializable)

Thanks for pointing me in the right direction. I'm an old programmer, but new to the web technologies.
