i can't get this exception...

Hi again..., i m actually trying to download the source code so i
could try to understand the error a bit more and ask a bit less... but
up to now i 'm still asking for help and 'd be extremely grateful if
somebody gives me a hand with this...,

i 'm still trying to figure out the app of my last post..., and having
solved the server classpath problems (coping .jar to the
$OZONE_HOME/lib directory)

the thing goes simply... i start the server..., launch the app (entry
point class) and it explodes in pieces... like this:

Exception in thread "main" org.ozoneDB.OzoneInternalException:
java.lang.InstantiationException: PostImpl

	at java.lang.Thread.run(Thread.java:534)


All this generated "at TestOz.main(TestOz.java:26)" which is:
Post post = (Post)  (db.createObject(PostImpl.class.getName(), 0,
"postNro: "+ nro));

i 'd appreciatte somebody translate to me that exception...
thanks in advance and good night.
