You have two errors. A faiure to load your servlet because a
class cannot be found.

Then a second error because a problem was encountered in
reporting the first error.

Then things get nasty because you get a problem reporting that
error ...

You should look at where you have put your HelloWorldServlet
class file and whether it in turn needs any other classes.

To improve the error repoting define an error reporting servlet.

I suggest that you download the 3.5 handbook from

www.redbooks.ibm.com

You will find more detail here.
