I'm really confused. I can't figure this out:

10:58:33,671 ERROR [HibernatePlugIn] Rethrowing exception...
org.hibernate.PropertyNotFoundException: Could not find a getter for axleType in
class ca.cummings.dto.Trailer

but in ca.cummings.dto.Trailer i have:

int axleType;
public int getAxleType() {
return this.axleType;
}

What does you axleType.hbm.xml look like?

Heres Trailers.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

<property name="year"/>
<property name="gvw"/>

<!-- everything is ok but this one -->
<property name="axleType" type="int"/>

Spent all morning trying to figure this out...

Deleted my binaries, recompiled. The I finally shut down eclipse, deleted everything, rebooted, restarted Eclipse recompiled and it works.

Well, I just tried setting an int valued entity in my test application and everything worked OK, so I don't think it's hibernate's problem per se.

A couple of things:
1. Did you cut/paste your java code to the message or re-type it? Any chance you have Axel instead of Axle?
2. I notice that you are returning this.axleType. The 'this.' is not really needed since the scope of axleType is unambiguous in this method. This is not causing your issue, however, because I tried that out as well.
3. Any reason why you are not declaring axleType as private?

I'll play around a bit more but hopefully someone else will see something that can help you.

If your shop allows it, try out the netbeans 4.1 release - It's not all that bad.
