I are having trouble installing Cocoon 2 (via the CVS as described on
http://xml.apache.org/cocoon2/install.html). I am using it together with
a Tomcat 3.2.3-1 Debian package and some problems have occured.
First, I suspect that, since I am running both Cocoon and Tomcat on a
remote server (which I access via SSH) the Tomcat engine has a problem
with opening an X connection when AWT is invoked by Cocoon 2 (is it? it's
a guess). I tried to patch this by setting the DISPLAY environment
variable to localhost:47 in the /etc/init.d/tomcat shell script but that
did not make it work, though it changed the behaviour since Tomcat
stopped crashing and we got an error message in the browser instead.
Check the log snapshot from cocoon.log below:

Now, also it seems that our Cocoon 2 is having problems reaching
JdbcConnection, look below:

Also, there is a complaint that the sitemap handler's sitemap is not
available. This is also the error being printed on the error message page
being displayed in the browser as I try to access :8081/cocoon/. Check
the third and last log snapshot below:

Thank you for your patience - I hope it is possible for someone to give a
solution to this problem.
