Newbee....

Trying to following HelloWorld sample in Chapter 2.
Currently working on section 2.2.1 Using Hibernate Annotations...

Hibernate version:
Hibernate 3.2
Hibernate-annotations-3.3.0.GA

Ant Target code:
<target name="schemaexport" depends="compile, copymetafiles"
description="Exports a generated schema to DB and file">

<hibernatetool destdir="${basedir}">
<classpath>
<pathelement path="${build.dir}"/>
<pathelement location="lib/hibernate-commons-annotations.jar"/>
<pathelement location="lib/ejb3-persistence.jar"/>
</classpath>
<annotationconfiguration
configurationfile="${build.dir}/hibernate.cfg.xml" />
<hbm2ddl
drop="true"
create="true"
export="true"
outputfilename="helloworld-ddl.sql"
delimiter=";"
format="true"/>
</hibernatetool>

</target>

hibernate.cfg.xml:
<!DOCTYPE hibernate-configuration SYSTEM
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriver</property>

<property name="show_sql">true</property>
<property name="format_sql">true</property>


<mapping resource="hello/Message.hbm.xml"/>

</session-factory>
</hibernate-configuration>

Found the problem.

I included the library hibernate-common-annotations.jar and not hibernate-annotations.jar. I find this library in the lib folder and thought that it was a typo in the book.
