I sort of figured it out.
There are three Java Flow examples. The 3rd one is:
org.apache.cocoon.samples.flow.java.PersistenceFlow
If I comment out the reference to it in the samples sitemap.xmap file
the other 2 work. With it there all 3 break since it tries to load the
class when the sitemap is ran. I am NOT sure but I think it has to do
with this class using ojb

Where is your cocoon app running in ?
I've been using jboss 3.2.7 some time and had to put some libraries into
the lib/endorsed dir to get things working,

When I try to goto any of the java flow samples I get the error below.
I am using Cocoon 2.1.7. Thanks in advance for any help I receive. I
have been looking for hours and been trying IRC. Thanks - David
