Hi All, In EJB spec, it is given as below at page no 119.
A client can get a reference to an existing entity object�s remote interface in any of the following ways:
1) Receive the reference as a parameter in a method call (input parameter or result). 2) Find the entity object using a finder method defined in the entity bean�s remote home interface. 3) Obtain the reference from the entity object�s handle. (see Section 9.11)
Can somebody explain first one? I assume client can receive reference as ONLY RETURN parameter in method call. What is input parameter mentioned in the bracket.
Assume you have two clients C1 and C2 accessing an entity bean E1. C1 looksup E1 and passes the reference to the beans remote object to a C2's method as a parameter. This is just one case substantiating the point 1. Its a simple thing, but sounds so difficult in the spec - An entity bean's remote object's reference can be received as a parameter of a method.

Thanx Keerthi. Indeed it is simple but sounds difficult to understand.
