Looks like hbm2java ant task as shown in "Hibernate in Action" book has changed from H3 onwards. The example shown on page 363 doesnt seem to be supported anymore.

I skimmed through the forum and looks like many people have figured out ways.

Can somebody help me with the exact ant script to generate pojos from hbm files and list of required jars to be placed in the ant classpath?

Thank you.

Maybe this will give you an idea ;-)

thanks to Alex's pointer

My hbm2java ant task is working as expected.

This is what i had to do.

<target name="hbm2java" depends="init">
<taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask" classpath="${classpath}" />
<hibernatetool destdir="${generated.pojo.dir}">
<configuration>
<fileset dir="${hibernate.mappings.dir}" />
</configuration>
<hbm2java />
</hibernatetool>
</target>

Classpath

commons-logging-1.0.4.jar
velocity-1.4.jar
velocity-tools-generic-1.1.jar
hibernate3.jar
hibernate-tools.jar
dom4j-1.5.2.jar
