Hey Amit

What I think That you should use Stringified format for all the attribute
s Of
Composite keys.

Like You make a String which is a Concatenation of string form of Differe
nt
fields of Composite keys  by getting stringified form by calling toString

method on each attribute.


 Suppose   fname (String) rollNo (Integer) 

String str=3D fname.toString()+roolNo.toString();
 use str As Composite key It is Serializable Object.

Also you can consult Chapter 9 Of o'reilly Enterr prise java Beans.


Hope It will Help You out.

Otherwise  you can use hashCode method also to concatenate to make a Comp
osite
key.

Hi
I am interested in knowing how to write a Pk file in case i want to deplo
y
an Entity bean which maps to a table having composite primary key. I want
 to
know this for Weblogic 6.o with ejb specs 2.0.
If anybody has an example of such a bean please mail me the entire bean
example.

also in ejb specs 2.0 the get and the set methods are abstract.

n
the Remote interface file???
