Exception in thread "main" NoClassDefFoundError

[Shraga van Shufel]

Hello,
I think I am struggling with a known prob but I can't seems to figure it out.
I have a simple class and I am getting the above error when I try to run it from the command line.
when I try to run it from an IDE no problem.
public class Test {
public static void main(String [] args){
System.out.println("it works");
}
}
I set the classpath to the location of the class and also try to run the program using
# java -classpath . Test.class
if I echo the classpath I am getting to correct path
what am I doing wrong ?
thanks in advance
Shraga.

hi Shraga
Firstly, please edit your code to following which I recommand

 
public class Test 
{
 public Test()
 {
  System.out.println("it works"); 
 }
 public static void main(String [] args)
 {
   new Test();
 } 
}
 

And then save the file named
Test.java
Do you compile the programme once before run it?
if no,please do the following
javac Test.java
then run the programme
java Test
oo...
If you do the above state and can not run it,
Please feel free to let me know
thanks
