Problems after installing Quicktime for java

Question

Hi
I just recently installed Quicktime for java on my computer. Previous to this installation I was running j2sdk1.4.2_03 and this was working fine (compiling and running code) for me. But since I installed QTjava all I can do is compile code.
I have reset my class path back to
CLASSPTH = .;C:\j2sdk1.4.2_03\bin
and my path to
PATH = ........... .;C:\j2sdk1.4.2_03\bin
When I try to run a simple helloworld programe I get the following error
Exception in thread "main" java.lang.NoSuchMethodError: main
I konw that this is something to do with my classpath, but I cann't figure out what is wrong, any ideas would be greatly appricatied

Answer 1

the programe I am running is as follows
public class hello
{     public hello ()
     public void main (String [] args)
     {     System.out.println ("Hello world");
It compiles fine but I get the above error when I run it. It is the same for other more complex programes I have written which contain a main mettod.
