Dear friends,

Problem: hbm2java in version 3 do not generate the class defined within the composite-id tag. But in version 2 it was generating the class co.omx.coon.resource.hibernate.beans.AccountGroupSubSupplierKey. is it a bug in version 3?

Here's my Map

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

<class name="com.omx.common.resource.hibernate.beans.AccountGroupSubSupplier" table="ACCOUNT_GROUP_SUB_SUPLR" >

<composite-id class="com.omx.common.resource.hibernate.beans.AccountGroupSubSupplierKey" name="accountGrpSuplrKey" unsaved-value="none">
<key-property name="accountGroup" column="ACCOUNT_GROUP" type="string" ></key-property>
<key-property column="SUB_SUPLR_ID" name="subSupplierId" type="big_decimal"/>
</composite-id>

<property name="subSupplierStatus" column="SUB_SUPLR_STATUS" type="string" />
<property name="lastModDate" column="LAST_MOD_DATE" type="date" />
<property name="lastModBy" column="LAST_MOD_BY" type="string" />
</class>

</hibernate-mapping>


and here's the java code generated by hbm2java

package com.omx.common.resource.hibernate.beans;

import java.io.Serializable;
import org.apache.commons.lang.builder.ToStringBuilder;


/** @author Hibernate CodeGenerator */
public class AccountGroupSubSupplier implements Serializable {

/** nullable persistent field */
private String subSupplierStatus;

/** nullable persistent field */
private java.util.Date lastModDate;

/** nullable persistent field */
private String lastModBy;

/** full constructor */
public AccountGroupSubSupplier(String subSupplierStatus, java.util.Date lastModDate, String lastModBy) {
this.subSupplierStatus = subSupplierStatus;
this.lastModDate = lastModDate;
this.lastModBy = lastModBy;
}

/** default constructor */
public AccountGroupSubSupplier() {
}

public String getSubSupplierStatus() {
return this.subSupplierStatus;
}

public void setSubSupplierStatus(String subSupplierStatus) {
this.subSupplierStatus = subSupplierStatus;
}

public java.util.Date getLastModDate() {
return this.lastModDate;
}

public void setLastModDate(java.util.Date lastModDate) {
this.lastModDate = lastModDate;
}

Thanks for your time.
Chicagoram.
public String getLastModBy() {
return this.lastModBy;
}

public void setLastModBy(String lastModBy) {
this.lastModBy = lastModBy;
}

public String toString() {
return new ToStringBuilder(this)
.toString();
}

}

you are probably using hbm2java for hibernate 2, you should use the tools.hibernate.org for hibernate 3

Max,

I'm using org.hibernate.tool.hbm2java.Hbm2JavaTask.

I appreciate your help.

Thanks

use the latest tools instead - tools.hibernate.org

Max,

My ant task generates the following error

Did you find the solution for this problem ?
If yes, can you let us know ?
Thanks,
EDH

as i wrote, use the libs that comes with the tools to avoid any version mismatches.

Using maven plugin hibernate3-maven-plugin, I get the error in hbm2java

[INFO] Trace
org.hibernate.MappingException: class ProjectTeam$Id not found while looking for property: projectId

This only started coming as soon as I added <composite-id> to my intermediate table. Here is the hbm file

This is what I ended up doing
Changed

to


Changes
1. No inner class (changed ProjectTeam$Id --> ProjectTeamId)
2. defined types for the members of the composite key

1) hbm2java doesn't support generate innerclasses for composite-ids
2) specifying types for properties is a requirement to use a code generator (unless you want java.lang.Object for all your types)
