Entity class not found/InvocationTargetException

Hello community,

I'm rather getting a confusing error i can't find solutions on the net. Let me show you my Hibernate configurations and mapping files

OverrideItemDo exists on za.co.epsilon.domain package. Could this be related to a conflict of jar files i have on my class path?

antlr-2.7.6.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
javassist-3.12.0.GA.jar
required\jta-1.1.jar

Try specifying the fully qualified name of the class in your Hibernate mapping file. Like this:

<class name="za.co.epsilon.domain.OverrideItemDo" ... >

Likewise with other classes, such as OverrideItemId.

changed it to

	<session-factory name="">

now i get

My problem is not with mapping but using hibernate attach.clean

getSession().load(batchOverrideDoIns, LockOptions.NONE);

error
