I recently installed J2EE on my machine. I deployed the CMP Example using the default Cloudscape database. I experimented with trying to use an Access and a SQL Server database but was unsuccessful in connecting to the datasource I set up from the ODBC configuration tool. I'm running WinNT 4.0 by the way. I registered the sun.jdbc.odbc.JdbcOdbcDriver and used the JDBC url jdbc dbc:testdb that I've used to successfully to connect with both DBs outside the deploytool. Is this possible? The JNDI naming conventions are foreign to me. Can you substitute a SQL Server or Access DB for the CMP example?
