My build.xml file creates a table, however it would only create the table that the hibernate-2.1 folder provides.

Here is my build.xml file:

<?xml version="1.0"?>
<project name="test" default="db" basedir=".">

<property name="source.root" value="src"/>
<property name="class.root" value="classes"/>

<path id="project.class.path">

In the src folder that is provided to us in the hibernate-2.1 folder, in net.sf.hibernate.odmg there is a Name.java class and a Name.hbm.xml file . Here are those 2 files:

//$Id: Name.java,v 1.3.2.1 2003/08/09 11:24:47 turin42 Exp $
package net.sf.hibernate.odmg;
import java.io.Serializable;

/**
* An ODMG name that may be bound to a persistent object.
*/
public class Name {
private String name;
private Class persistentClass;
private Serializable id;
public Name(String name, Class persistentClass, Serializable id) {
this.name = name;
this.persistentClass = persistentClass;
this.id = id;
}
public Name() {}
/**
* Returns the name. JavaDoc requires a second sentence.
* @return String
*/
public String getName() {
return name;
}

/**
* Returns the persistentClass. JavaDoc requires a second sentence.
* @return Class
*/
public Class getPersistentClass() {
return persistentClass;
}
/**
* Sets the name. JavaDoc requires a second sentence.
* @param name The name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* Sets the persistentClass. JavaDoc requires a second sentence.
* @param persistentClass The persistentClass to set
*/
public void setPersistentClass(Class persistentClass) {
this.persistentClass = persistentClass;
}
/**
* Returns the id. JavaDoc requires a second sentence.
* @return Serializable
*/
public Serializable getId() {
return id;
}
/**
* Sets the id. JavaDoc requires a second sentence.
* @param id The id to set
*/
public void setId(Serializable id) {
this.id = id;
}
}





Here's Name.hbm.xml:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping SYSTEM "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >
<hibernate-mapping>

<!-- A default mapping for the ODMG Name class. Applications
may specify their own mappings instead. -->

<class name="net.sf.hibernate.odmg.Name">
<id name="name" type="string">
<generator class="assigned"/>
</id>
<property name="persistentClass" type="class" not-null="true"/>
<property name="id" type="serializable" not-null="true"/>
</class>
<query name="byName">from n in class net.sf.hibernate.odmg.Name where n.name = ?</query>
</hibernate-mapping>


Now in the hibernate-2.1 folder I created my own foler called practice9. I copied and pasted the src folder given to us.

Now it creates the Name table in my database which is good.

However when I create my own .java and hbm.xml files it won't work. Why is that? When I type ant schema in the command line I get the error that the persistent class is not found. So if I had a COllection.hbm.xml file and a Collection.java file it would say 'persistent class Collection not found'.

Also, about my build files, my database is MySQL 4.0. So I was wondering if this part of my build.xml file was right:

<target name="db" description="Runs HSQLDB database management UI
against the database file--use when application is not running">
<java classname="org.hsqldb.util.DatabaseManager"
fork="yes">
<classpath refid="project.class.path"/>
<arg value="-driver"/>
<arg value="org.gjt.mm.mysql.Driver"/>
<arg value="-url"/>
<arg value="jdbc:mysql:${data.dir}/music"/>
<arg value="-user"/>
<arg value="sa"/>
</java>
</target>


Thx for all the help!
