[CLUE-Tech] NoClassDefFoundError

[Joseph Thomas]

Hello all,

ok I had java running on my red hat linux fine, but recently I am unable to 
run my java programs through the terminal, but I am able to run them in my 
IDE (eclipse)

Here is the code ( a simple hello world ):

public class HelloWorld {

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

}


And here is the error I am getting:

[phierce at localhost test]$ java HelloWorld
Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld (wrong 
name: test/HelloWorld)
        at java.lang.ClassLoader.defineClass0(Native Method)

[phierce at localhost test]$ java test.HelloWorld
Exception in thread "main" java.lang.NoClassDefFoundError: test/HelloWorld

Any ideas on what causes this? Again I only recieve these errors when ran in 
a terminal window, but not in my IDE. I get this on ANY java program I try.

Thanks!
