I try to generate hbm.xml from my class CIngredientes but don't work.

java -cp [classpath] net.sf.hibernate.tool.class2hbm.MapGenerator org.enavarro.lamarinera.hibernate.CIngredientes

Result:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<!-- org.enavarro.lamarinera.hibernate.CIngredientes cannot be added, no UID found! -->
<hibernate-mapping>
</hibernate-mapping>

class2hbm.MapGenerator: executed.

My class:

package org.enavarro.lamarinera.hibernate;

import java.io.Serializable;

/**

*/
public class CIngredientes implements Serializable {

private String idIngrediente;
private String nombreIngrediente;

public String getIdIngrediente() {
return idIngrediente;
}

public void setIdIngrediente(String idIngrediente) {
this.idIngrediente = idIngrediente;
}

public CIngredientes() {
}

public CIngredientes(String idIngrediente, String nombreIngrediente) {
this.idIngrediente = idIngrediente;
this.nombreIngrediente = nombreIngrediente;
}

public String getNombreIngrediente() {
return nombreIngrediente;
}

public void setNombreIngrediente(String nombreIngrediente) {
this.nombreIngrediente = nombreIngrediente;
}
}

What is wrong?

Thanks

PD: Sorry my english

The class2hbm is very old and had not been maintain for quite some time. It has been dropped from the H3 tools package. The primary reason is that a class (non-annotated) has limited meta data facilties from which we can generate a reasonable mapping document.

The most common way to deal with this is to use XDoclet (or H3 annotations). The wiki has information on XDoclet (as does xdoclet itself) support for hibernate. There are many examples etc .
