Hm...you're a bit new at this right? =).
Allright, this is what you gotta do:
if your're running Windows 98...find the autoexec.bat file and select to edit it.
there will be a variable called classpath. Here, you must add an entry (path) to where the rt.jar file is found.
Let us assume that you installed jdk directly on to c:\. The jar file is usually found in jre\lib\rt.jar
so, you would add the following line:
.;C:\jdk\jre\lib\rt.jar
you must have that set for any of your programs to work at all. I would recommend you simply write a program that prints hello...do this:
import java.io.*;
public class PathTester
public static void main(String[] args){
System.out.println("I'm working");
If this doesn't work...you're in big trouble =). Once this works, you're ready to go. Give it a shot.
