Finder and ejbSelect Declaration 

The declaration of finders has not changed in CMP 2.0. Finders are still declared in the 

home interface (local or remote) of the entity. Finders defined on the local home interface do 

not throw a RemoteException. The following code declares the findBadDudes finder on the 

GangsterHome interface: 

public interface GangsterHome extends EJBLocalHome { 

Collection

findBadDudes

(int badness) 

throws FinderException

; 

} 

Listing 9 12, Finder Declaration 

The ejbSelect methods are declared in the entity implementation class, and must be public 

abstract just like cmp field and cmr field abstract accessors. Select methods must be 

declared to throw a FinderException, but not a RemoteException. The following code 

declares an ejbSelect method: 

public abstract class GangsterBean implements EntityBean { 

   public 

abstract

Set

ejbSelectBoss

(String name) 

throws FinderException

; 

} 

Listing 9 13, ejbSelect Declaration 

EJB QL Declaration 

The EJB 2.0 specification requires that every ejbSelect or finder method (except 

findByPrimaryKey) have an EJB QL query defined in the ejb jar.xml file.

 6

  The EJB QL 

query is declared in a query element, which is contained in the entity element. The following 

is the declaration for the queries defined in Listing 9 12 and Listing 9 13: 

         GangsterEJB 

findBadDudes
