having a problem using groovy within seam project

I have installed jboss tools 3.1cr1, eclipse, groovy plugin, seam 2.2 and as5.1

i create a seam project in eclipse (generates 4 projects on the disk) and enabled groovy on the ejb project and the web project.

i created a standard entity in java using the menus - no problem

I then create another entity as asubclass as a groovy entity see below

package org.domain.forsterslist.session;

import org.domain.forsterslist.entity.Person;
import org.jboss.seam.annotations.Begin;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.web.RequestParameter;
import org.jboss.seam.framework.EntityHome;

@Name("personHome")
class PersonHome extends EntityHome<Person>
{
     @RequestParameter Long personId;
     
     @Override
     public Object getId()
     {
          if (personId == null)
          {
               return super.getId()
          }
          else
          {
               return personId
          }
     }
     
     @Override @Begin
     public void create() 
     {
          super.create()
     }
}

this compiles ok and classes get generated into build/classes subdirectories

however when i deploy on the server i get class not found exception.  class loader cant find my groovy compiled class

how do i fix this?
