Problem with running java files

Hey!

I have just installed 1.5.0_06 and have set paths and what otherwise is necessary to run the java programs. I was testing the install and run a standard HelloWorld.java program

I got the following error:

Exception in thread main java.lang.NoClassDefFoundError: HelloWorld
