> I use the attribute "entity-name" in my class mapping, this is for mapping the same object many times on table(s), and all seem to work normally. I found a problem when I tried to join a table on another class mapping, like: 
>      <class entity-name="categoryDefault" name="ca.cie.pak.CategoryVO" table="CATEGORY">
> 		    <id name="id" column="CATEGORY_ID" type="java.lang.Integer">
>                 <generator class="native"/>
>             </id>
>             <property name="name" column="NAME"/>
>             
> 		 <bag name="contents" where="priority = 0"> 
> 		     <key column="CATEGORY_ID" />
> 		     <one-to-many entity-name="ContentSummary"/>
> 		 </bag>
> 		    
> 		 <join table="LAYOUT_CATEGORY">
> 		      <key foreign-key="CATEGORY_ID" column="CATEGORY_ID" />
> 	            <property  name="layoutId" column="LAYOUT_ID"/>
>             </join>  		    
> 		</class> 
> I found a ClassNotFoundException: categoryDefault. This exception is thrown when the HbmBinder.bindJoin method is called. I see the code and it tries to instantiate a class from the getEntityName and not by the className. 
> Someone can answer me if this is a XML mapping error or a real bug and what I need to do.
