Hi all
I have a plug-in, which is the core of our app. The plug-in is br.com.germantech.ecf

Now, I made a plug-in, and this plug-in will contribute to our core plug-in. This works fine, he added new menus and everything.
But turns out that this new plug-in will create new tables too...
So, I created a manifest like this

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Germantech - Industria
Bundle-SymbolicName: br.com.germantech.industria;singleton:=true
Bundle-Version: 0.0.1
Bundle-Activator: br.com.germantech.industria.ActivatorIndustria
Bundle-Vendor: German Tech Sistemas
JPA-PersistenceUnits: gtech-industria
Meta-Persistence: META-INF/persistence.xml 
Require-Bundle: org.eclipse.ui,
 org.eclipse.core.runtime,
 javax.persistence;bundle-version="2.0.4",
 org.eclipse.persistence.antlr;bundle-version="3.2.0",
 org.eclipse.persistence.asm;bundle-version="3.3.1",
 org.eclipse.persistence.core;bundle-version="2.4.1",
 org.eclipse.persistence.jpa;bundle-version="2.4.1",
 org.eclipse.persistence.jpa.jpql;bundle-version="2.0.1"
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Import-Package: br.com.germantech.ecf.api,
 br.com.germantech.ecf.aplicacao.helpers,
 br.com.germantech.ecf.dominio.modelo.produto,
 org.postgresql
Bundle-ActivationPolicy: lazy

and created a class like this

package br.com.germantech.industria.dominio.modelo;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

import br.com.germantech.ecf.dominio.modelo.produto.Produto;

@Entity
public class Producao implements Serializable {
	private static final long serialVersionUID = -4643897338650864928L;
	
	@Id @GeneratedValue(strategy=GenerationType.IDENTITY)
	private Long id;
	
	@Temporal(TemporalType.DATE)
	private Date dataProducao;
	
	@OneToMany
	private List<Produto> produtosFinalizados = new ArrayList<Produto>();

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public Date getDataProducao() {
		return dataProducao;
	}

	public void setDataProducao(Date dataProducao) {
		this.dataProducao = dataProducao;
	}
	
	public List<Produto> getProdutosFinalizados() {
		return produtosFinalizados;
	}
	
	public void setProdutosFinalizados(List<Produto> produtosFinalizados) {
		this.produtosFinalizados = produtosFinalizados;
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((id == null) ? 0 : id.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		Producao other = (Producao) obj;
		if (id == null) {
			if (other.id != null)
				return false;
		} else if (!id.equals(other.id))
			return false;
		return true;
	}
}

The class Producao is a class from our new plug-in, and the class Produto is a class from our core plug-in...
When I start the plug-ins, I see this:

Internal Exception: javax.persistence.PersistenceException: Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.4.1.v20121003-ad44345): org.eclipse.persistence.exceptions.EntityManagerSetupException

	... 12 more

My question is: how to map a class from one plug-in into another plug-in?
I tried to put Produto into the new plugin's persistence.xml, and that didn't worked too

thanks in advance
