Can you tell us what versions of tomcat, geoserver and java you have
installed please?

My first guess is that you need to install the java advanced image
libraries (JAI) and java image IO (jio) they are separate from the
normal JRE install

https://jai-imageio.dev.java.net/binary-builds.html

Hope this helps

Subject: Re: [Mapbuilder-users] Problem displaying map


Bit hard to say what the error is. My guess is there is something wrong 
with Geoserver - maybe a missing library or similar. I'd start by asking

the geoserver email list.

It is possible that Mapserver is sending a strange request to Geoserver 
which you can check using firebug to get the request, then put it into 
the Geoserver test page.
