Hi Jason and other members of Orion-Interest,
Is there anyone here that can help debug this persistent problem with
Orion? I have set up a simple recipe for Orion newbies (including
myself), and although everything looks fine, the servlet that should be
created to handle requests cannot be instantiated, and Orion does not
provide much information on what the problem might be.
IMHO a simple step-by-step guide is very important for the success of
Orion. Any help would be greatly appreciated.

Jason, first I suggest you upgrade to the latest version of Orion. There
are multiple ways of doing that:
* Download the orion-1.0rc1.zip but replace `rc1' with `rc2'
* Auto-update using the command: java -jar autoupdate.jar
* Replace your orion.jar with http://www.orionserver.com/orion/orion.jar
Perhaps you should do a combination of the above.
[ Question to the Orion team: What exactly is the recommended way to
upgrade to the ever-changing `latest' version? :) ]
Then concerning the problem you have: I had the same problem. So I
upgraded using the rc2 download. Autodeployment went just fine. But when
I pointed my browser to http://localhost:9092/orion-primer/ I got an
exception that said there was an error instantiating the servlet. There
was no extra information that allowed me to track the source of the
problem.
So I contacted Magic_EMC (Magnus Stenman) on the channel #orionserver or
#java on EFnet (an IRC chat network). He said he would change the code
so the complete stack trace would be printed in the log file
(orion/application-deployments/orion-primer/application.log) But I had
no luck autoupdating from my rc2.zip yet, so I haven't been able to
check that the information now prints out.
I currently get the following information printed in the application log
file:
5/25/00 5:18 PM Started
5/25/00 5:20 PM orion-primer-web: Started
5/25/00 5:20 PM orion-primer-web: Servlet error
javax.servlet.ServletException: Error instantiating default servlet

Any help would be greatly appreciated!
