Description

I'm trying to use Groovlet / GSP from within an embedded Jetty, and it's not working for me.

I want to distribute my web application as a single jar-with-dependencies. So i start an embedded standalone Jetty that serves the webapplication from the jar-with-dependencies build with the assembly plugin.

When I try to load a GSP I get this stacktrace:

When I try to load the Groovlet I get this stacktrace:

When I start the webapplication using the Jetty plugin i works perfectly.

I have attached a simple project to demonstrate the problem. Build it "mvn install" and start jetty either from the web app using the Jetty plugin (cd web; mvn jetty:run) or the standalone (cd standalone; java -jar target/standalone-1.0-SNAPSHOT-jar-with-dependencies.jar). The embedded Jetty listens on port 8080.
