I try to run the java-based AJAX viewer using the latest built installer
(Apache/Tomcat/Java configuration):

http://localhost:8008/mapguide/mapviewerjava/ajaxviewer.jsp?WEBLAYOUT=Library://Samples/Sheboygan/Layouts/SheboyganJsp.WebLayout

and I get this error message below:

-------- ERROR BEGIN -------------------

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it
from fulfilling this request.

exception

javax.servlet.ServletException: java.lang.NoClassDefFoundError:

note The full stack trace of the root cause is available in the Apache
Tomcat/6.0.14 logs.

------------- ERROR END ------------------

I haven't used the Java configuration in MapGuide before so could anyone
possibly explain what is going on here? I'm pretty sure I've set all the
MapGuide paths correctly. MgException exists in MapGuideApi.jar. What could
I possibly me missing here?
