Hi everyone,

I am using hibernate 2.1 and i m having some problems running SchemaExport. i have a class named AbstractUser which is:

package com.smartprice.eb.valueobject;

import java.io.Serializable;
import java.util.Collection;
import java.util.Iterator;

/**
* @author diniz
*
* @hibernate.class table="user"
*
* To change the template for this generated type comment go to
* Window>Preferences>Java>Code Generation>Code and Comments
*/
public abstract class AbstractUser implements ValueObject {

protected PK primaryKey;

protected String password;

public PrimaryKey getPrimaryKey() {
return getPK();
}

public void setPrimaryKey(PrimaryKey pk) {
this.primaryKey = (PK)pk;
}

public void setPrimaryKey(Serializable pk) {
if (pk instanceof Collection) {
Collection c = (Collection)pk;
Iterator it = c.iterator();
setPrimaryKey(new PK(((Long)it.next()).longValue(), (String)it.next()));
} else {
}
}

/**
* @hibernate.id generator-class="assigned"
*/
private PK getPK(){
return this.primaryKey;
}

/**
* @hibernate.property
*/
public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public static class PK implements PrimaryKey {

private long code;
private String login;

public PK() {
this(-1,null);
}

public PK(long code, String login) {
this.code = code;
this.login = login;
}

/**
* @hibernate.property
*/
public long getCode() {
return this.code;
}

/**
* @hibernate.property
*/
public String getLogin(){
return this.login;
}

public boolean equals(Object o){
AbstractUser.PK pk = (AbstractUser.PK) o;
if (this.code == pk.getCode() && this.login.equals(pk.getLogin())){
return true;
}
else{
return false;
}
}
}

}

After running hibernatedoclet task it s mapped to:

<hibernate-mapping>
<class
name="com.smartprice.eb.valueobject.AbstractUser"
table="user"
dynamic-update="false"
dynamic-insert="false"
>

<composite-id
name="PK"
class="com.smartprice.eb.valueobject.AbstractUser.PK"
>
<key-property
name="code"
type="long"
column="code"
/>

<key-property
name="login"
type="java.lang.String"
column="login"
/>

</composite-id>

<property
name="password"
type="java.lang.String"
update="true"
insert="true"
column="password"
/>

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

<joined-subclass
name="com.smartprice.eb.valueobject.Admin"
dynamic-update="false"
dynamic-insert="false"
>
<key
column=""
/>

</joined-subclass>
<joined-subclass
name="com.smartprice.eb.valueobject.Buyer"
dynamic-update="false"
dynamic-insert="false"
>
<key
column=""
/>

</joined-subclass>
<joined-subclass
name="com.smartprice.eb.valueobject.Seller"
dynamic-update="false"
dynamic-insert="false"
>
<key
column=""
/>

</joined-subclass>

</class>

</hibernate-mapping>

When i run the schemaexport task it gives the following:

BUILD FAILED

Does anyone know why it doesn't find the AbstractUser.PK class?

Regards,

Leonardo

I forgot to say that the classpath is set to:

<path id="lib.class.path">
<pathelement path="${database.driver.classpath}"/>
<fileset dir="${lib.dir}">
<include name="*.jar"/>
</fileset>
<fileset dir="/home/leorazuk/work/fapemig/lib/xdoclet">
<include name="*.jar"/>
</fileset>
<fileset dir="${build.dir}">
<include name="*.jar"/>
</fileset>
</path>

and the jar in ${build.dir} has all the classes inside it. If i try to generate the schema for classes with no composite-id, it works fine.
