Originally posted by Wild Bill: import oracle.jdbc.driver.OracleConnection; import oracle.jdbc.driver.OracleDriver; //Create a new Driver and Load the DriverManager OracleDriver dbDriver = new OracleDriver(); DriverManager.registerDriver(dbDriver); //Get aconnection to the database this.conn = (OracleConnection)DriverManager.getConnection(dbMachinePath, userName, userPasswd); I don't like this, since the code is no longer portable and this is not the purpose behind the JDBC framework.

23. Having a problem connecting to Oracle using JDBC type 2 OCI driver    coderanch.com

I can guess that this is probably a classpath issue. It looks like the container is not providing the Oracle driver classes to your application. In general, command line applications make use of the CLASSPATH environment variable, or a classpath specified as a command-line parameter when the application is started. Servers, on the other hand, usually ignore the system CLASSPATH and ...
