Ever wanted to use Continuations or WebSockets in one of your projects? This is quite painful, because the current version of GWT (2.0.3) has only a jetty with version 6.1 embedded.

The current stable version of jetty is 7 and version 8 is in development.

Use of gwt-jetty

Just add de.csenk.gwt.jetty-<version>.jar to your classpath and start your GWT project with the following additional argument:

-server de.csenk.gwt.jetty.JettyLauncher

And finally your GWT application would be served by a jetty server with the referenced version.
