Hibernate version:
Hibernate version3.0

Hi,
My hibernate.cfg.xml looks something like the following:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@10.130.30.37:10920:widev</property>
<property name="hibernate.connection.username">username</property>
<property name="hibernate.connection.password">password</property>

<!-- Mapping files -->
<mapping resource="Message.hbm.xml"/>
</session-factory>
</hibernate-configuration>


My build.xml when I use schema export utility looks something like:

<target name="init-db" description="Creates the app database.">
<taskdef classname="org.hibernate.tool.hbm2ddl.SchemaExportTask" classpathref="project.class.path"
name="schemaexport"/>
<schemaexport delimiter=";" drop="no" output="${basedir}/sql/oracle/generated/hbSchema.sql"
config="${class.destdir}/hibernate.cfg.xml" quiet="no" text="no">
</schemaexport>
<fileset dir="${basedir}">
<include name="**/*.hbm.xml"/>
</fileset>
<echo message="hibernate config file found in ${class.destdir}/hibernate.cfg.xml"/>
</target>

where I have defined project.class.path and class.destdir. But when I try to run build.xml init-db I am getting the following errors. Could you please tell me why??

I am getting the same thing. Were you ever able to find the cause of this?

could it be you have not set the connection provider to anything else than UserProvidedConnection ?
