Question

I'm trying to call an entity bean froma session bean i get the error :-
7/02/27 14:35:25 javax.ejb.ObjectNotFoundException: Exception [EJB - 10008]: Cannot find bean of type [SalesBean] using finde
[findByCustID].

7/02/27 14:35:25       at oracle.toplink.internal.ejb.cmp.finders.Finder.checkNullResult(Finder.java:224)
My session bean looks like this :-
public class HelloBean implements SessionBean
  public String helloWorld (String pzCustomerID) throws SQLException,RemoteException
     String lzRevenue=null;
     int liCustomerID=Integer.parseInt(pzCustomerID);
     try
          Context initial = new InitialContext();
          Object objref =   initial.lookup("SalesBean");
          SalesHome salesHome =(SalesHome) PortableRemoteObject.narrow(objref,SalesHome.class);
          Sales sales=salesHome.findByCustID(liCustomerID);
          lzRevenue=(String) sales.findByCustID(liCustomerID);
My entity bean looks like this:-
public class SalesBean implements EntityBean
  public String factPK;
  public int timeID;
  public int custID;
  public int locID;
  public int itemID;
  public int entityID;
  public String currency;
  public float qty;
  public float unitPrice;
  public float amount;
  public EntityContext context;
  private Connection con;
    private void makeConnection() {
        try {
            InitialContext ic = new InitialContext();
            javax.sql.DataSource ds = (javax.sql.DataSource) ic.lookup("jdbc/DSource");
            con = ds.getConnection();
        } catch (Exception ex) {
            throw new EJBException("Unable to connect to database. " +
                ex.getMessage());
  public SalesBean()
  public String ejbFindByCustID(int custID) throws SQLException,RemoteException,FinderException
     makeConnection();
     PreparedStatement pstmt = con.prepareStatement("select sum(amount) from sales where cust_id= ? ");
     pstmt.setInt(1, custID);
     ResultSet rset = pstmt.executeQuery();
     if (!rset.next())
          throw new RemoteException("no records present" );
     return rset.getString(1);
  }My entity bean's home interface looks like this:-
public interface SalesHome extends EJBHome
public Sales create() throws RemoteException, CreateException;
public Sales findByCustID(int custID) throws SQLException,RemoteException,FinderException;
My entity bean's remote interface looks like this:-
public interface Sales extends EJBObject
     public String findByCustID(int custID) throws SQLException,RemoteException,FinderException;
my ejb-jar.xml looks like this:-
