I have used static nested classes in struts to populate a html list from database objects. If you are using struts you might find them handy.

Database drivers (jdbc,odbc,.net...) are provided by database vendors or third party vendors and not generated. JDBC drivers are loaded into the JVM at runtime.

It works pretty fine. I think your source file name is different than the class name i.e., PayrollApp. Rename the source file to PayrollApp.java.

import java.sql.DriverManager;
import java.sql.Connection;
/**

You are required to mention the database name too which u r missing. Jst add the db name as given below

try{
Class.forName("org.gjt.mm.mysql.Driver");
