Component Class not found with Composite ID

Hi Guys

Have to following problem
when I try to build the Export Schema for the database in NetBeans with XDoclet I get the following exception
D:\java\build.xml:27: Schema text failed: component class not found: com.data.HibernateID

My Classes look like this:

Code:

package com.data;


/**
 * 
 *
 * @hibernate.class
 *     table="NEW_HIBERNATE_BEAN"
 *
 */
public class NewHibernateBean{

   private NewHibernateBeanID id;
/**
  *   @hibernate.id
  *      unsaved-value="any"
  */
   public NewHibernateBeanID getId () {
      return id;
   } 
   public void setId (NewHibernateBeanID id) {
      this.id = id;
   }

}

and

Code:

package com.data;

import java.io.Serializable;
/**
 * 
 *
 * @hibernate.component
 *    
 *
 */


public class NewHibernateBeanID implements Serializable{
    
   
   private String test;
   /**
    *   @hibernate.property
    */
   public String getTest() {
       return test;
   }
   public void setTest(String test) {
       this.test = test;
   }

    
    public int hashCode() {
        return 0
    }

    public boolean equals(Object obj) {
        return true;
    }

    
}

The follwing .hbm.xml file is generated

Code:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping
>
    <class
        name="com.data.NewHibernateBean"
        table="NEW_HIBERNATE_BEAN"
    >

        <composite-id
            name="id"
            class="com.data.NewHibernateBeanID"
            unsaved-value="any"
        >
                     <key-property
                        name="test"
                        type="java.lang.String"
                        column="test"
                />

        </composite-id>

 

        <!--
            To add non XDoclet property mappings, create a file named
                hibernate-properties-NewHibernateBean.xml
            containing the additional properties and place it in your merge dir.
        -->

    </class>

</hibernate-mapping>

I really dont know why this does not work.

Hope you can help me!

Thank you in advance!

YIPPIE, Hurray!!!

I finally solved the problem!!

Thought it might be interesting for you:

I had to add the class-path in the extensionsProperties file for ant!!

Here you can see it:

Code:

<target name="hibernate-schema-export" depends="init,project-extension-init">
    <taskdef name="schemaexport" classname="org.hibernate.tool.hbm2ddl.SchemaExportTask" classpath="[b]${hibernate.classpath}[/b]"  />
    <schemaexport properties="extension/hibernate.properties" quiet="no" text="no" drop="no" delimiter=";" output="${basedir}/${build.dir}/schema-export.sql">
      <fileset dir="${build.classes.dir}">
        <include name="**/*.hbm.xml" />
      </fileset>
    </schemaexport>

this variable is set in the extenstionsProperties:

Code:

hibernate.classpath = ${libs.hib-cglib-full.jar.classpath}:\
${libs.hib-commons-collections.jar.classpath}:\
${libs.hib-commons-logging.jar.classpath}:\
${libs.hib-concurrent.jar.classpath}:\
${libs.hib-dom4j-1.jar.classpath}:\
${libs.hib-ehcache.jar.classpath}:\
${libs.hib-hibernate.jar.classpath}:\
${libs.hib-jdbc-driver.jar.classpath}:\
${libs.hib-jdbc2_0-stdext.jar.classpath}:\
${libs.hib-jta.jar.classpath}:\
[b]${build.classes.dir}[/b]

Wow, I am so glad that it finally works!!

huh ? there is no hibernate.classpath read anywhere so this sounds very crazy.

the classpath should be in the hibernatetool task.
