I've Isolated My Problem Down To This

If I run any Java program in my c:\java, I get the NoSuchMethodError for main. Somehow, main is not getting recognized at run-time.
However, if I copy my source program to c:\java\com\gfarms\geometry and add the following statement
at the top of the file:
package com.gfarms.geometry; then compile in c:\java\com\gfarms\geometry and run it by saying:
java com.gfarms.geometry.Gary it runs!!

Check your CLASSPATH environment variable and make sure you have "." (the current directory) listed in it, as in ".;c:\java" . I think I had the same problem once and that was the cause.

Lay you odds that there is another Gary.class out there that does not have a main that is getting picked up from the classpath. When you don't SPECIFICALLY say which class file to run by using the package, the OTHER one gets run and you get an error.

You could be right Cindy, maybe the error I got before was a "class not found" error
I agree. Here's the link:
