Re: Can't fix java.lang.ClassNotFoundException problem

I'm working in Eclipse. My app runs fine within the IDE. I get the
ClassNotFoundException error when I try to run it from the command line.

My application is HelloWorld.java. It has a main and is a basic Hello
World application.

class HelloWorld {

        public static void main(String[] args) {
                System.out.println("Hello World !");

        }

}

Eclipse builds the project.

projectdir/bin has HelloWorld.class
projectdir/src has HelloWorld.java

$ java -version

How do I run my java application from the command line ?

Thanks !
