Databases and servlets

Question

I'm writing an application that displays all the records in a database using servlets, everything works as it should when run under Tomcat 3.2.3. I've since installed the Win32 version of Apache and the JServ plugin. This works fine except when asked to run the servlet that accesses a database. The servlet loads OK but an exception is thrown when accessing the records (See below). Does anybody have any ideas why this is? Thanks.
Exception thrown:
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Answer 1

If you're using the jdbc-odbc bridge that ships with the Java api's, then you need to create the Driver and the Connection.
You need lines that look something like:
Driver driver = (Driver) Class.forName(driverName).newInstance();
Connection con = DriverManager.getConnection( dataSourceURL, UserName, Password);
