Letting Breed Entity bean set it own Type CMR 2. Getting a controller the Session bean to set the Type CMR on the Breed Entity. For example session bean contains (breed.setType(type)       ----- Original Message ----- From: Dmitri Colebatch To: [EMAIL PROTECTED] ; [EMAIL PROTECTED] Sent: Monday, January 07, 2002 11:00 AM Subject: Re: Can Entity Bean Reference Another Entity Bean using Lookup what is the jndi you are looking up?  is it by any chance "java:comp/env/ejb/OtherEJB" or something similar (the comp/env/ejb bit)?  If so, then what is happening is the session bean has a reference to the other entity bean, but the entity bean does not.  The answer is then in your deployment descriptors.   there no doubt could be 10 other answers, but this springs to mind.   hth dim ----- Original Message ----- From: Glenn Dickson To: [EMAIL PROTECTED] Sent: Monday, January 07, 2002 1:28 PM Subject: Can Entity Bean Reference Another Entity Bean using Lookup Hi all   Just wondering :   Is it possible for a local entity bean to contain code that lookups another local entity.   Setting Description:   An entity bean called Breed is must contain entity Type. I pass a Value Object to the Breed bean.  The bean :     obtains the TypeId PK from the VO.     looks up the JNDI name (errors here, see description below) for the TypeHome     finds the Type record using the TypeId (PK) via the FindbyPrimaryKey function for the TypeHome.     sets it type CMR to the found type record   Error Description: but an error occurs here while doing the lookup. It says, that the JNDI name cannot be found.   However, if I move this to a session bean which does exactly the same. It works. For clarity the session bean:     accepts the Value Object     obtains the TypeId PK from the VO.     looks up the JNDI name  for the TypeHome (works!!!!)     finds the Type record using the TypeId (PK) via the FindbyPrimaryKey function for the TypeHome.     sets it type CMR to the found Type record   Why???????? Does it work in the session and not entity.   TIA Glenn
