Make sure you have the jar, and that the classpath is set correctly.masijade.a at 2007-7-9 5:48:56 >

So download it from MySQL. I can't really help you with administrative issues on your PC. If you wish to use a specific software on your machine, it is, essentially, up to you to make sure that that software is installed. go to http://www.mysql.org/ and download the ConnectorJ MySQL JDBC Driver and include it on your classpath. If you do not know how to do this, then take lessons in "basic internet use" for the download, and go through the "Getting Started" Java tutorial from http://java.sun.com/

As you are using the com.mysql.jdbc.Driver, you have to tell the compiler where to find the specified class....That is, you need to specify the .jar path in the class path...otherwise, use ODBC..jintokla at 2007-7-9 5:48:56 >
