I could not find update for Hibernate 3.2cr3 so tried to do it myself. There are 2 files needed for update - hibernate3.jar in lib dir and hibernate-client.jar in client dir. The first one is available from http://sourceforge.net/project/showfiles.php?group_id=40712&package_i..., but the second one - not. I've checked the JBoss-EJB3 http://fisheye.jboss.org/viewrep/JBoss/jboss-ejb3/build.xml, found the code for building hibernate-client.jar, changed it a bit and pasted to build.xml of hibernate bundle. Here is the code: <target name="client" depends="jar" | description="JBoss EJB3 hibernate-client.jar"> | <!-- build hibernate-client.jar --> | <!-- <unjar src="${hibernate.hibernate.lib}/hibernate3.jar" | dest="${build.classes}" /> --> | <jar jarfile="${dist.dir}/hibernate-client.jar"> | <zipfileset src="${jar.path}"> | <include name="org/hibernate/AssertionFailure.class"/> | <include name="org/hibernate/**/*Exception.class"/> | <include name="org/hibernate/collection/**"/> | <include name="org/hibernate/exception/Nestable*.class"/> | <include name="org/hibernate/exception/ExceptionUtils.class"/> | <include name="org/hibernate/engine/SessionImplementor.class"/> | <include name="org/hibernate/loader/CollectionAliases.class"/> | <include name="org/hibernate/persister/collection/**"/> | <include name="org/hibernate/pretty/MessageHelper.class"/> | <include name="org/hibernate/type/Type.class"/> | <include name="org/hibernate/EntityMode.class"/> | <include name="org/hibernate/util/**"/> | <include name="org/hibernate/proxy/**"/> | </zipfileset> | </jar> | </target> | Just add it after the last and build using "build client". For those who don't like building yourself i've uploaded it http://slil.ru/23046264. sverker, maybe you can check it yourself and make a new copy of your build?
