I'm trying to write a simple servlet that will return a gif to the caller.
Below is the servlet code, and the error from jserv.log.

Enviro:
RedHat 6.0
ApacheJserv 1.0
BlackDown jdk1.2

Also - I am running an xserver.

thanks!

I am getting the following error - and I have an xserver running.  Below is
the servlet and the error I'm getting in jserv.log.

Any help would be appreciated!
