My Problem is when my computer is not connected to internet, i cannot use schemaexport to db. Is that any way to use it without internet connection. Thanks.[/b]

It works fine on my computer without connection.

Are you sure you are using the right hibernate jar with the right dtd ?

Please tell me what's wrong with my setting. I Still cannot export schema without internet.

I'm using ant task to do schema export, here is my code :

<target name="schemaexport" depends="init">

<taskdef name="schemaexport"
classname="org.hibernate.tool.hbm2ddl.SchemaExportTask"
classpathref="schema.lib.path"/>
<schemaexport
config="${build.java.dir}/hibernate.cfg.xml"
output="${build.dir}/schema-export.sql">

</schemaexport>
</target>


and hibernate.cfg.xml :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 2.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

</hibernate-configuration>

I'm using lib :
hibernate3.jar
hibernate2.jar

look at your DTD reference! Why does it say hibernate 2 when you are using hibernate 3 ?

You are right. I change the version to 3.0 and it works.
Thank u very much.
