Hi Werner, Thanks for your response......
* I wonder why you chose EJB QL as your preferred query language?* Because Object Query Language (OQL) is compatible as described in the ODMG 3.0 specification section 4.12. and OQL is nearly identical to EJB QL I visited the http://docs.codehaus.org/display/CASTOR/CastorSocProjects - Create class hierarchy to define OQL queries programmaticaly also know as "query objects". - Analyze properties of a given example entity and transform it into "query objects". This approach is known as "query by example". - Parse queries with current CastorQL syntax using ANTLR and transform them into "query objects". - Parse queries with EJB QL syntax using ANTLR and transform them into "query objects". I thing you and Ralf together subdivided the problem and also shown the way of doing it. Although I was also thinking the same because I have been through docs specifically for OQL query engine.
