Tutorial: Using EJB Query Language

This tutorial describes how the Financial Brokerage Service (FBS 10g) sample application uses the EJB Query Langauge (EJB QL), a feature introduced in the EJB 2.0 specification. Using a syntax similar to SQL, EJB QL enables you to write queries based on Entity Beans without knowing anything about the underlying relational schema.

This tutorial assumes that you are familiar with the FBS 10g and have installed and configured the required software as described in About the Financial Brokerage Service.
