Re: Development Environment, -noserver

I described this a bit when describing how SuperDevMode works: http://blog.ltgt.net/how-does-gwts-super-dev-mode-work/

When you run in -noserver, you only launch the "code server", to which the GWT DevMode plugin in your browser will connect. To trigger a DevMode session that uses that plugin rather than compiled-to-JS code, you just add ?gwt.codesvr= to the query-string of your HTML page, giving the "code server"'s address (host and port) as the value.

Ideally, you'll point the "-war" of DevMode to an exploded-war directory served by your server (so DevMode can generate some files at the right place) and pass "-startupUrl" with the URL of your HTML host page, as served by your server. Upon startup, DevMode will tell you exactly which URL to open in your browser (i.e. it adds the appropriate gwt.codesvr to the URL's query-string so you just have to copy/paste).

Hi,
  
   I need additional information about the -noserver option. I have an embedded jetty server that needs to run on its own
since I have multiple GWT components enclosed in different projects that fit into different places (Putting all GWT
components within the very same project and use the embedded jetty is not an option for me).

Reading the explaination about the -noserver option I seam to quite miss a point (or at least I am not sure if my
understanding is correct). So please help me out.

I do not understand how things work when the GWT's Jetty is not start up.
From reading the source, I catched that a second port (something in the 9xxx) is created.

But I do not understand how serving a page with my very own server instance and viewing it in a browser (or Selenium)
will trigger a debug session. What do I miss here?

My first guessing is that GWT still creates some sort of server I need to connect to within the browser and every request
is handed over to my own server beside GWT related requests.

Can someone please clearify this? It would be very good if I can just startup the dev server and run a certain GWT project
to debug the component in isolation.


Thanks for reading,
