I was trying to use the Persistent base class pattern.

I am using xdoclet tags to generate my hbm files.

All I get is "<XDocletMain.start 54 ) <<Class com.axium.poc.ContactInfo misses ID property>>" however...

I want it to use the ID from the Persistent base class. What am I doing wrong?

package com.poc.base;

import net.sf.hibernate.*;

import java.io.Serializable;
import java.sql.SQLException;

/**
* @hibernate.class
*/

public abstract class Persistent implements Serializable {

protected Long _id;
protected int _version;

/**
* @hibernate.id
* column="id"
* generator-class="assigned"
*/
public Long getIdentifier() {
return _id;
}

public void setIdentifier(Long id) {
_id = id;
}

public int getVersion() {
return _version;
}

public void setVersion(int version) {
_version = version;
}


}

I assume I have to specify some id tag in the child class.. but I am unsure how to do this.

I am sure this is something simple.. appreciate your assistance.


Is there more documentation on how to use the 'Persistent' base class. The one I found had the class code but not really much else.

In the case above...

Would you also implement a method 'getContactInfoId()' which calls the 'getIdentity()' from the base case?

Just not sure how to take advantage of this base Persistent class properly.

There obviously has to be some way to tell hibernate which database field the 'ID' attribute maps to.

i.e. ContactInfo --> ID (getIdentity) is contactInfoId
Foo -> ID (getIdentity) is FooId
etc

Can someone clear this up a bit for me?

I do base class property inheritance wo any pb.
