Hello,
I have a simple java class I am using to try to learn how to use hibernate shown below. I get this ClassCastException with any class I try to persist using hibernate. I think it is probably a configuration issue but I'm stumped. Anyone know what I am doing wrong?

public class Widget{
private String comments;
private int id;
public Widget(){
}

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getComments() {
return comments;
}
public void setComments(String comments) {
this.comments = comments;
}
}


Hibernate version:
3
Mapping document:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class entity-name="Widget">
<id name="id" type="int">
<generator class="native"/>
</id>
<property name="comments" type="string"/>
</class>
</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():
tl.set(session);
Transaction tx = session.beginTransaction();
Widget w = new Widget();
w.setComments("mycomment");
session.save(w);
tx.commit();
