ClassCastException on a simple query

birwin · **Joined:** Wed Nov 29, 2006 6:55 pm **Posts:** 10

I am working on my first Hibernate project. I have a fairly simple Query that I am trying to run, but no matter what I do, I get a ClassCastException. below are three attempts to query the database for a Client object:

Code:

Criteria criteria = session.createCriteria(Client.class);
criteria.add(Expression.eq("clientId", clientID));
return (Client)criteria.uniqueResult();

Code:

Query query = session.createQuery("from Client where clientId = " + clientID);
return (Client)query.uniqueResult();

I replaced it with this code and get the same exception

Code:

Client client = (Client) session.get(Client.class, clientID);
return client;

I have verified that the clientID used in the examples above is valid and the query does return an object. It only fails when I attempt to cast the object as a Client object.

When I step through the code and view the object in my "Expressions" window of Eclipse, it appears to be a Client object. It is only when I try to cast it to a Client, that I get this error.

I was reading something about proxies and am wondering if I am getting a proxy object instead of the object I am expecting...

I am not sure why this code would throw the ClassCastException.

Sorry about the wild goose chase, it turns out I was stepping through the code from the wrong method call. The method call that was throwing the error was returning a null object.

Error Fixed....

I later saw this error with my Employee object and it turned out that the error was caused by my mapping file and POJO. I had a property defined as an int value. In the database there was a null value in that field. When Hibernate tried to assign null to a primitive, this exception was thrown. I changed my ints to Integers where appropriate, and no more error.
