Eyeball Installation Problem

Hi,

After I installed the eyeball, which didn't pass the ant test
only 1 build error, so I ignored it for now..

And I was trying to use java jena.eyeball
It gives me the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: com/hp/hpl/jena/rdf/m

        ... 6 more

How should I fix it? Thanks a lot

(you probably want the users list users@jena.apache.org)

NoClassDefFoundError means that then class definition existed when the 
currently executing class was compiled, but at runtime.  It is usually a 
problem with setting the classpath at runtime.

Make sure you have the right versions of Jena for Eyeball.
