ng template dao/daohomebase.ftl
[hibernatetool] freemarker.core.InvalidReferenceException: Expression clazz.hasN
aturalId is undefined on line 200, column 6 in dao/daohomebase.ftl.

This is my

<target name="GenerateDAO" depends="GenerateDAOBase">
<hibernatetool destdir="${build.dir}/generated">
<configuration configurationfile="hibernate.cfg.xml" />
<hbmtemplate
templateprefix="dao/"
template="dao/daohome.ftl"
filepattern="com/dao/{class-name}DAO.java">
<property key="jdk5" value="false" />
<property key="ejb3" value="false" />
</hbmtemplate>
</hibernatetool>
</target>

are you sure you are using a hibernate 3.2. jar ? use the jar that comes with the tools to make sure they are compatible.

Thanks for your reply.

I am using the same Hibernate jar that are coming with hibernate tools. Any thing else that i could be missing?

Thanks in Advance.

Is it a component mapping? Please post the mapping file you think it is failing on.

Thanks for your Reply.
Still i am not able to generate the Code. Please find the my Mapping xml.
