Exception in thread "main" java.lang.NoClassDefFoundError
OK, I'm going to be really dumb, here.
I'm completely new toJAVA and am trying to teach myself using theJ2EE Tutorial found on the http://www.sun.com website.
Basically, I've created a*.java file and compiled it fine. However, when I try to run the file I get the following error.
Exception in thread "main" java.lang.NoClassDefFoundError: echo (wrong name: Echo)

Put simply, I don't have the first clue what to look for, where to go, or what might be wrong with the file. I also don't know what other information may be of use to anyone who can help me.
