In general the best way to self test is to start off at your {context name}/index.jsp which automatically does a query to get your
Registry Type. Then simply experiment with the other jsp pages. You will find "browse.jsp" the most used.
Update.jsp is used for updating or adding new xml resources to the registry. This currently is done with a text box, file upload, or public url. A Xforms
ability is getting closer, but is currently not in this version.
