Hi
An ejbSelect() method is a query method just like finder method but it can
be used internally only.
A situation you want to use ejbSelect() method, for example, is when you
have a home method called ejbHomeGetTotalBankValue() which add up to totals
of all bank account values in the bank table. In this case the container
should generate JDBC for you in ejbSelect() method then you call this method
from ejbHomeGetTotalBankValue() method.
public abstract double ejbSelectAllAccountBalances()
throws FinderException;
public double ejbHomeGetTotalBankValue() throws Exception {
// Get a collection of bank account balances
Collection c = this.ejbSelectAllAccountBalance();
// Loop through collection and return sum
}
In this case ejbSelect() method return container-managed field, which is
collection of double value
