Im use j2sdk 1.6.0_04, OS Windows Vista, and eclipse_3.2.2
plugin i have installed is hibernate core 3.2.5, hibernate tools 3.2.0 beta9a,
sysdeo Tomcat Plugins 3.2.1, V4All 2.1.1.9, sql explorer 3.5.0 RC5.
why my Ant does'nt work to create java class from hbm.xml?
Have I miss something? like classpath or include the jar file in my project or other? I remember i have set all.
Sory for my english, is not better enough. He3.
Anyway thx for helping.

Structure of my project:

BuildingAnt
|-.settings

|-bin

|-lib

|-Testing.hbm.xml


This my Testing.hbm.xml file:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping>

<class name="Testing">

<property name="id" type="java.lang.String"/>

<property name="test" type="java.lang.String"/>

</class>
</hibernate-mapping>


This my build.xml an Ant's file:
<?xml version="1.0"?>
<project name="BuildingAnt"
default="codegen" basedir=".">

<!-- Set up properties containing important project directories -->
<property name="source.root" value="src"/>

<path id="project.class.path">
<!-- Include our own classes, of course -->
<pathelement location="${class.root}" />
<!-- Include jars in the project library directory -->
<fileset dir="${lib.root}">
<include name="**/*.jar"/>
</fileset>
</path>

<!-- Teach Ant how to use Hibernate's code generation tool -->
<taskdef name="hbm2java"

classpathref="project.class.path"/>

<!-- Generate the java code for all mapping files in our source tree -->
<target name="codegen"
description="Generate Java source from the O/R mapping files">

<hbm2java taskname="hbm2java" output="${source.root}">
<fileset dir="${source.root}">
<include name="Testing.hbm.xml"/>
</fileset>
</hbm2java>

</target>
</project>
