Well I've made progress. I an run jython in the servlet.
But now I get:
javax.servlet.ServletException: Traceback (most recent call last): File
"C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\demo\ui.py",
line 1, in <module> from eu.webtoolkit.jwt import WtServlet
java.lang.NoClassDefFoundError: Could not initialize class
eu.webtoolkit.jwt.WtServlet
Any help here?
I have put the jwt libraries (2) in demo\WEB-INF\lib

I think I got most of the classpath stuff resolved except for
import javax.servlet.http.HttpServlet
What jar are you using to resolve that one?

Hi Jason,
as this is clearly Jython
specific, you might have more success getting answers on the Jython mailing
list.
There are possibly Jython mechanism to use jars without even touching the
classpath (as there is in JRuby and Groovy).
Cheers

Ok, so my CLASSPATH needs the JAR name, my mistake. But Jetty has a ton of
files. That's going to be one long classpath! Is there a length limit or some
other way to make those available to jython?
