Background: I am trying to use ini4j for the purpose of parsing config files in the ini format.
I run the command: javac -classpath ini4j-0.5.4.jar Driver.java and the compilation goes smoothly…however when I attempt to run the program running: java Driver I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/ini4j/Ini
at Clock.main(Clock.java:13)
Caused by: java.lang.ClassNotFoundException: org.ini4j.Ini

From what I understand this error is a product of the jvm being able to find the class file being referenced in the error and failing. I checked the ini4j jar file and confirmed that the Ini.class file does in fact exist. Can anyone please tell me what am I missing here ?
The following is my source code:
import java.util.Map;
import java.io.IOException;
import java.io.File;
import org.ini4j.* ;
public class Driver{
public static void main(String[] args){
System.out.println("running in Clock-J main()");
String fileName = "./test.ini" ;
File fileObject = new File(fileName);
try{
Ini ini = new Ini(fileObject);
}catch(IOException e){
String exception = e.toString() ;
e.printStackTrace();
}
}
}
