[Vara Prashanth]

Hi all

I am just a starter to JDOM so my question may come as a wild one to some of
you gold haired ppl.

I installed the beta 7 version, followed the instructions like placing the
xerces.jar file on my classpath. When I compile a sample java file
SAXBuilderDemo.java....i dont get an error but when I run it I get the
following message(s)

Exception in thread "main" java.lang.NoClassDefFoundError: SAXBuilderDemo
(wrong
 name: samples/SAXBuilderDemo)

What else could I be missing out on?

Please shoot in your suggestions

Thanx
