I am evaulating JBoss for the server part of a client-server system. As well as controlling session managament for clients, the server has to process large volumes of data. I am trying to find out if I can access the embedded Hypersonic db directly, and then read/write to it using JDBC. I want to do this because each transaction for a client may involve lots of database rows. I need the speed, and mapping the rows to entity objects makes no sense in the application's context. Does anyone know of any information relating to direct use of the db from within ejb's or pojo's running in the server? Raj.
