I am new to Ruby/RoR and would appreciate any help on the issue I am trying to resolve far past 2 days. I have a java application as a jar and I have included in the controller as below. require 'java' require 'C:/Documents and Settings/user/Desktop/application.jar' include_package 'whatever.something' After that I am calling a method from one of the classes in the jar. puts Java::WhateverSomething::Engine.helloWorld() This helloWorld() program does a very complex thing :) and returns an id string that I am trying to display in the console. This external application has a call to the DB. I have the driver jar in the application.jar. Also, I have included in the RoR java runtime library and all places I can think of but still I am getting the 'Class Not Found' exception. Can someone point what I am doing wrong? java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at java.net.URLClassLoader$1.run(URLClassLoader.java:200) ... java.sql.SQLException: No suitable driver at java.sql.DriverManager.getConnection(DriverManager.java:545) at java.sql.DriverManager.getConnection(DriverManager.java:171) ... Thanks.
