Hi,
I'm having problems generating my database with hbm2ddl.  I tried a simple mapping but it doesn't seem to work and I don't get any error messages (I use hibernate 3.2.0ga, hibernate-annotation 3.2.1.ga and hibernate-tools 3.2.0 beta )
Here is my cfg file: 
Code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- Mapping for localization context -->
        <mapping class="org.dataisland.primitives.bean.LocalizationContext"/>
    </session-factory>
</hibernate-configuration>
Here is (part of) my class containing the annotations:
Code:
package org.dataisland.primitives.bean;
...
/**
 * Localization context
 */
@org.hibernate.annotations.Entity(dynamicUpdate=true)
@javax.persistence.Table(name="LOCALIZATION_CONTEXT")
public class LocalizationContext implements Serializable {
...
    private String id;
    private boolean system;
    String humanReadableKey;
    List locales = new ArrayList();
    @javax.persistence.Id
    @javax.persistence.GeneratedValue(generator="uuid")
    @org.hibernate.annotations.GenericGenerator(name="uuid", strategy = "uuid.hex")
    @javax.persistence.Column(name="ID", length=32)
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    @org.hibernate.annotations.Type(type="boolean")
    @javax.persistence.Column(name="SYSTEM")
    public boolean isSystem() {
        return system;
    }
    public void setSystem(boolean system) {
        this.system = system;
    }
    @org.hibernate.annotations.Type(type="string")
    @javax.persistence.Column(name="HUMAN_READABLE_KEY")
    public String getHumanReadableKey() {
        return humanReadableKey;
    }
    public void setHumanReadableKey(String humanReadableKey) {
        this.humanReadableKey = humanReadableKey;
    }
    @org.hibernate.annotations.CollectionOfElements(fetch=javax.persistence.FetchType.EAGER )
    @javax.persistence.JoinTable(name="LOCALIZATION_CONTEXT2LOCALE", 
                                 joinColumns = @javax.persistence.JoinColumn(referencedColumnName="LOCALIZATION_CONTEXT_FK"),
                                 inverseJoinColumns = @javax.persistence.JoinColumn(referencedColumnName="LOCALE"))
    @org.hibernate.annotations.IndexColumn(name="WEIGHT")
    public List<Locale> getLocales() {
        return locales;
    }
    public void setLocales(List<Locale> locales) {
        this.locales = locales;
    }
...
}
And finally here is my ant task: 
Code:
    <target name="create.tables">
        <mkdir dir="${sql.output.dir}"/>
        <taskdef name="hibernatetool" classname="org.hibernate.tool.ant.HibernateToolTask">
            <classpath refid="hibernate.classpath"/>
        </taskdef>
        <hibernatetool destdir="${sql.output.dir}" >
            <classpath>
               <pathelement location="${lib.dir}/dataisland-primitives.jar"/>
                <pathelement location="${classes.dir}"/>
            </classpath>
        
           <annotationconfiguration configurationfile="${cumul.conf.test.dir}/hibernate.cfg.xml"
                                    propertyfile="${cumul.conf.test.dir}/hibernate.properties"/>
           <hbm2ddl outputfilename="create-tables.sql" drop="true"/>
        </hibernatetool>
    </target>
Which gives this output: 
Code:

BUILD SUCCESSFUL
As you can see, no classes seem to be mapped, nothing was created in the database and I have no error messages.
Any clue what my problem is?
Thanks
