[LibGDX - HTML5] Not able to remove query string from URL

Hi guys! I’m trying to start working on web projects. This is all new for me, and I’m having some weird issues.

I created a new project with “gdx-setup” (libgdx 1.3.1, desktop and html only, with projects files for eclipse). I didn’t use gradle to import it into eclipse luna, just used the old way of “import existing projects into workspace”.
So far, so good. I can run without problems the desktop version, and also the html version (RUN AS–>Web Application).
The URL that eclipse gives me looks something like this:

http://127.0.0.1:8888/index.html?gwt.codesvr=127.0.0.1:9997

SuperDev button appears (but it doesn’t seems to work) and game starts (runs at 2-3 fps, which is pretty normal, right?)
So…everything looks “fine” at this point, except for the SuperDev button.
Then…I want to remove the query string from the URL to be able to test the game at full speed, so I use this URL:

http://127.0.0.1:8888/index.html

A message box from chrome shows up saying that “GWT module ‘html’ has to be recompiled”, I click OK and…nothing happens.
Checking eclipse IDE everything looks that is still running. But on the “Development Mode” tab, shows:

-Module html has been loaded.
-Unloading module html (html).

I tried a LOT of things. I cant get this work. On the RUN as Wep Application the config is:
Project: TestingWEB-html
Main class: com.google.gwt.dev.DevMode
Server: run build-in (yes)
GWT: both definitions xml files
Arguments: -war “C:\Proyectos Java\TestingHTML\html\war” -remoteUI “${gwt_remote_ui_server_port}:${unique_id}” -startupUrl index.html -logLevel INFO -codeServerPort 9997 -port 8888 com.shuken.testing.GdxDefinitionSuperdev com.shuken.testing.GdxDefinition

I’m really lost. What is missing?
