I am converting hibernate 2.1.8 to Hibernate 3.0.4. I am using Hbm2javaTask from hibernate-tools-3.0alpha1 to generate java from hbm files. But Hbm2JavaTask could not find any mapped classes. I have generated class in the same directory as hbm files, and I even add java file to the class path and add config attribute to specify the all hbm files. But Hbm2javaTask from hibernate-extensions-2.1.3 work fine at same senerio. Could anyone shine some light on my problem. Thanks!


Here is my ant target:

<target name="generate-hibernate-classes" depends="init"
description="Generating Hibernate Java Sources from Hibernate Mapping files">
<taskdef name="hbm2java" classname="org.hibernate.tool.hbm2java.Hbm2JavaTask">
<classpath refid="hibernate.lib.path"/>
<classpath refid="hibernate-tools.lib.path"/>
<classpath refid="vo.path"/>
</taskdef>
<echo message="hibernate.dialect=${hibernate.dialect}" file="${cm.lib.dir}/hibernate.properties"/>
<hbm2java config="${dev.dir}/manager/descriptors/manager/unittest-esm-config.xml" output="${dev.src.dir}">
<fileset dir="${dev.src.dir}">
<!--include name="**/*.hbm.xml"/-->
<include name="**/UserPreferenceVO.hbm.xml"/>
<include name="**/AccountVO.hbm.xml"/>
</fileset>
</hbm2java>
</target>


Here are the two hbm files:

<?xml version="1.0"?>

</class>

</hibernate-mapping>

Here is the exception I got.

Use the hibernatetool task instead. There is an Ant tasks doco for tools in CVS. I forget where.

<taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask">
<classpath>
<path refid="hibernate-tools.classpath"/>
</classpath>
</taskdef>

<hibernatetool destdir="${gen.dir}">
<configuration>
<fileset dir="${src.dir}>
<include name="**/*.hbm.xml" />
</fileset>
</configuration>
<hbm2java/>
</hibernatetool>

Thanks for the reply.

But I could not fine org.hibernate.tool.ant.HibernateToolTask in hibernate-tools-3.0alpha1. Does any one knows what jar file should I download to get this tool.

Thanks!

I've been building from CVS, which is alpha3. You should probably do that. It's still alpha software, so a released jar isn't any better than a CVS jar at this point.
