Hibernate version:
hibernate-3.2
Hi
Im trying to write an ant target which generates a ddl from annotated classes. The annotated classes are packaged in a jar-file entities.jar and works fine in my J2SE application.
Im running Ant in eclipse - here is a part of my build.xml that should do the magic:
---------------------------------------------------------
<path id="toolslib">
<path location="lib/hibernate-tools.jar" />
<path location="lib/hibernate3.jar" />
<path location="lib/freemarker.jar" />
<path location="lib/mysql-connector-java-3.0.14-production-bin.jar" />
<path location="lib/hibernate-annotations.jar" />
<path location="lib/ejb3-persistence.jar" />
<path location="lib/hibernate-entitymanager.jar" />
<path location="lib/jboss-archive-browsing.jar" />
<path location="lib/javaassist.jar" />
<path location="lib/commons-logging-1.0.4.jar" />
<path location="lib/dom4j-1.6.1.jar" />
</path>
<taskdef name="hibernatetool"
classname="org.hibernate.tool.ant.HibernateToolTask"
classpathref="toolslib" />
<target name="hibernate">
<hibernatetool destdir="${build.home}">
<jpaconfiguration persistenceunit="manager1"/>
<classpath>
<path location="${build.home}/WEB-INF/lib/entities.jar" />
</classpath>
<hbm2ddl export="false" outputfilename="sql.ddl"/>
</hibernatetool>
</target>
---------------------------------------------------------
When running the target hibernatetool -verbose the output is:

---------------------------------------------------------
hbm2ddl fails because it cannot fint the the class javassist/bytecode/ClassFile. BUT the class is in the jar javaassist.jar as defined in the path.
Is this a bug? Or, is something else missing?
