I'm facing problem while running schema export ant task
1) my ant target reads this ...

<target name ="schema" depends="compile">
<taskdef name="schemaexport"
classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask"
classpathref="project.class.path"/>
<schemaexport properties="${class.root}/hibernate.properties"
quiet="no" text="no" drop="no" delimiter=";">
<fileset dir="${class.root}">
<include name="**/*.hbm.xml" />
</fileset>
</schemaexport>
</target>

2) my config file reads this ...

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping
PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="Track" table="TRACK">
<meta atrribute ="class-descriprion">
Represent Single payable track
</meta>
<id name="id" type="int" column="TRACK_ID">
<meta attribute="scope-set">protected</meta>
<generator class="native"/>
</id>
<property name="title" type="string" not-null="true"/>
<property name="filepath" type="string" not-null="true"/>
</class>
</hibernate-mapping>

when i try to execute ant goal from my console it says ...

Read the documentation!

can u let me know to which document i need to look for this

-Balaji

Man, just click on the "Tools" button and then on "Documentation". Is that too hard to find?

your defined ant task is only user for Hibernate2,here is a example for Hibernate3:

Of course you must get Hibernatetools3 at here http://www.hibernate.org/255.html

This is a great tool. But I have a problem with this guy Christians attitude!
I came across this post because I was having the same problem as Balaji and probably the same as he, thought I'd check to see on this forum if there was anything specific I was doing wrong.
It's absolutely appalling that you respond like that. Shame on you! I assume you're here with the intention of helping people? Learning a new tool on your own initiative can be an overwhelming experience to say the least!
