hello friends,
Can ejbFindByPrimaryKey return object of anyother type other than String.
Can i write
public Enumeration ejbFindByPrimaryKey(String pk) instead of
public String ejbFindByPrimaryKey(String pk).
when i write public Enumeration ejbFindByPrimaryKey(String pk) in my code, when i generate the jar file it gives me an error saying findbyprimarykey is not defined in home interface even though i had defined it...
thanks in advance
Jyothi

jyothi,
The Ejb spec 1.1 defines single object finders and Multi Object finders. This is defined in page 114 of the ejb specification. The return type of an finder method defined in the Home interface is a remote reference of the entity bean and that of a multi finder is a Collection/Enumeration of remote references.
Now the return type of a single finder in the Ejb is the Primary Key and that of a multi finder is a Collection/Enumeration of the Primary Key.
code for single finders from ejb spec

code from ejb spec for multi finders

Hope this helps.
