Hey Jens,
A log4r logger that connects up to a Java logger would be very useful
for keeping all the logs together.
Setting the servlet to load on startup can be done in the web.xml:
<servlet>
<servlet-name>test</servlet-name>
<servlet-class>nz.ac.auckland.ec.TestServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
Cheers,
Robert
