Hibernate version: 3.0rc1

I have some simple objects that I was originally planning to write my own persistence layer for, but decided to try out hibernate instead.

In a class I have a simple method like this:

protected void setFactory( CampaignFactory factory ) {
this.factory = factory;
}


factory is a transient property and I've haven't mentioned it in the mapping file.

When trying to use this method to set my transient property I get:

java.lang.IllegalArgumentException: Protected method: setFactory(Lcom/taglab/campaigner2/CampaignFactory;)V
at net.sf.cglib.proxy.MethodProxy$1.invoke(MethodProxy.java:55)
at org.hibernate.proxy.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:134)
at com.taglab.campaigner2.Campaign$$EnhancerByCGLIB$$20c97667.setFactory(<generated>)
at com.taglab.campaigner2.CampaignFactory.getCampaign(CampaignFactory.java:241)


Which looks like cglib doesn't like the visibility of my method. I tried changing it to public, and then I don't get the error.

However I'm reluctant to leave it as public since it is internal and not part of my public API.

Is it supposed to be this way, or am I barking up the wrong tree?

I've been trawling documentation for hours now... I can't find anyhing that shed any light on this?

This is now starting to seriously throw my API design off.

It seems I can't have any non-public business methods on my persisted objects. Is it really supposed to be that way?

I have a very similar problem where a protected method is used to enforce a business rule recursively, in a hierarchy of objects.

Apparently it is fixed in Hibernate 3.0: http://opensource.atlassian.com/project ... se/HHH-222

I still need to try that though....
