After migration of our EJB application from jboss 3.0.6 to
3.2.0 the following exception started to occur upon
invocation of entityContext.getEJBObject(). The EJB
DOES have well defined remote interface. According to
spec, getEJBObject() should be available in methods
where an instance is associated with the bean. In my
case the invocation is inside business method
PartnerBean.getRemoteObject() which is being called
from business method of CustomerBean.
getPartnerRemote():

public abstract class MMSBean {
protected EntityContext entityContext;
public void setEntityContext(EntityContext
entityContext)

{ this.entityContext = entityContext; }

public void unsetEntityContext()

{ this.entityContext = null; }

public EJBObject getRemoteObject()

{ return entityContext.getEJBObject(); //EXCEPTION HERE }

...
}

public abstract class PartnerBean extends MMSBean
implements EntityBean {
...
}

public abstract class CustomerBean extends MMSBean
implements EntityBean {
public PartnerRemote getPartnerRemote()

{ Partner partner = getPartner(); //CMR method: Partner has 1-to-1 relationship with Customer. return partner == null ? null : (PartnerRemote) partner. getRemoteObject(); }

}

Exception stack trace is below. $Proxy396 is a Customer
Bean proxy. $Proxy397 is a Partner Bean proxy.

java.lang.IllegalStateException: No remote interface
defined.
