@JoinColumn with compositePK and multiinheritance.

I've searched a lot around internet and I didn't find any solution to my
problem. Any help will be so appreciated.

I'm using Servicemix 4.5.3 and I have all my dependencies installed (other
operations are running perfectly).I'm getting this exception with OpenJPA

application.persistence.entities.serviceregistry.Service.interfaces" defines
a target of "userId" for join column "userId", but that target does not
exist in table "Service"

I have the following entities.

@Entity
public class Service {

private ServicePK compositePrimaryKey;
private String wsdlFile;
private Collection<ServiceInterface> interfaces = new
HashSet<ServiceInterface>();

@EmbeddedId
public ServicePK getCompositePrimaryKey() {
return compositePrimaryKey;

...setters and getters

@ManyToMany
@JoinTable(name = "SERVICE_IMPLEMENTATION", joinColumns = {
@JoinColumn(name = "tenantId", referencedColumnName = "tenantId"),
@JoinColumn(name = "userId", referencedColumnName = "userId"),
@JoinColumn(name = "serviceName", referencedColumnName =
"serviceName") }, inverseJoinColumns = {
@JoinColumn(name = "interfaceName", referencedColumnName =
"interfaceName"),
@JoinColumn(name = "XMLNamespace", referencedColumnName =
"XMLNamespace") })
public Collection<ServiceInterface> getInterfaces() {
return interfaces;

ServicePK is another class to construct my composite primarykey is as
follow.

@Embeddable
public class ServicePK extends TenantUserOwnedEntityPK {

private String serviceName;

public ServicePK() {}

public ServicePK(String tenantId, String userId, String serviceName) {
super(tenantId, userId);
this.serviceName = serviceName;

public String getServiceName() {
return serviceName;

public void setServiceName(String serviceName) {
this.serviceName = serviceName;

@Override
public boolean equals(Object obj) {
if (super.equals(obj) & obj instanceof ServicePK) {
ServicePK pk = (ServicePK) obj;
return this.serviceName.equals(pk.serviceName);
} else {
return false;

@Override
public int hashCode() {
return super.hashCode() + this.serviceName.hashCode();

Finally this PK has a super class to get another field for the composite
key.

@Embeddable
@MappedSuperclass
public class TenantUserOwnedEntityPK extends TenantOwnedEntityPK {

private String userId;

public TenantUserOwnedEntityPK() {}

public TenantUserOwnedEntityPK(String tenantId, String userId) {
super(tenantId);
this.userId = userId;

public String getUserId() {
return userId;

public void setUserId(String userId) {
this.userId = userId;

@Override
public boolean equals(Object obj) {
if (super.equals(obj) & obj instanceof TenantUserOwnedEntityPK) {
TenantUserOwnedEntityPK pk = (TenantUserOwnedEntityPK) obj;
return this.userId.equals(pk.userId);
} else {
return false;

@Override
public int hashCode() {
return super.hashCode() + this.userId.hashCode();

As you can see in this last class it's our field userId (The one that the
@ManyToMany relation complains about). When my DB is constructed from my
entities the Service table is as follow.

Table "public.service"
Column | Type | Modifiers
-------------+------------------------+-----------
tenantid | character varying(255) | not null
userid | character varying(255) | not null
servicename | character varying(255) | not null
wsdlfile | text |
Indexes:
"service_pkey" PRIMARY KEY, btree (tenantid, userid, servicename)
Referenced by:
TABLE "service_implementation" CONSTRAINT
"service_implementation_tenantid_fkey"
FOREIGN KEY (tenantid, userid, servicename)
REFERENCES service(tenantid, userid, servicename) DEFERRABLE

BTW I'm using Postgres 9.3.11 and openJPA 2.2.0.

How can I use that userId for a joincolumn in my relations? I have this kind
of mapping in other places and I'm getting the same error.

Thank you very much for everything.
