Re: GWT New Project doesn't start because of Jetty problems.
Yeah you were right. It works now, the only thing is that it doesn't show the gwt elements in the page.

Re: GWT New Project doesn't start because of Jetty problems.
Sorry, hit send too early - when using CodeServer, you should be sure to start your own tomcat - for whatever reason, that error message at localhost:8080 indicates that tomcat isn't running or isnt reachable at that port.

Re: GWT New Project doesn't start because of Jetty problems.
At a glance, it appears that you started CodeServer rather than DevMode - but the default port would have been rather than 8080 if your app was hosted by DevMode.

There are a few options I would suggest: * Upgrade to GWT 2.10 (especially since this is a new project). This is probably the simplest and best option. The new version of Jetty used there will not have this issue with scanning module files. * Stop using DevMode as an application server - run your own server, using the servlet container of your choice, and either pass -noserver to DevMode, or switch to CodeServer.
