Problems with tutorial from GWT

I have never used GWT before so I am trying to run through this basic tutorial google offer.
I have a simpe to question, hopefully. It  arises from my attempt to run through the tutorial regarding the  Google Web Tools tutorial for eclipse,

From the "Compile and run in Production Mode" section.

For this section it says to enter  the URL into the browser now I have tried a few different ways to do this
this dispalys "error1.png" (see the attached) as well as the below in the console box in eclipse.

[WARN] 404 - GET /MyWebApp/war/MyWebApp.html ( 1412 bytes

b) file:///C:/Users/Owner/Project/MyWebApp/war/MyWebApp.html

This second ways seems to work? Is this is what is meant in the tutorial. I just want a clear understanding of what is happening here. Thanks.

The tutorial says:
"To see the final application, open the file MyWebApp/war/MyWebApp.html in your web browser."

So I suspect that yes - it means open the file from your file system.

You do not have a webserver running and this application is not deployed anywhere yet. In order for any HTTP request to be served, you need a server :) Further down it says:
"You could now deploy your application to production by serving the HTML and JavaScript files in your MyWebApp/war/ directory from your web servers."

So if you have a web server, you can deploy these files there. But I suspect that this is covered in another tutorial - this one seems to be for really basic stuff so you can get started.

Do you have any web server installed? Try and just in case but I do not see anything in the tutorial about actual webservers...

Did you successfully do "Run locally in Development Mode"?

PS: That tutorial is a bit strange so I am not sure what they mean in half of the places and I use the API :) But then I Am used to SUn style tutorials I suspect.

I have Tomcat installed and I tried http://localhost::8080/MyWebApp/war/MyWebApp.html in my web browser got the following error on the browser.

HTTP Status 404 - /MyWebApp/war/MyWebApp.html

type Status report

message /MyWebApp/war/MyWebApp.html

description The requested resource (/MyWebApp/war/MyWebApp.html) is not available.
Apache Tomcat/6.0.24

Yeah I succesfully got the "Run locally in Development Mode" part going. I think its just running from the computers file system. Its just a bit confusing
The new generation of project management tools

With’s project management tool, you can see what everyone on your team is working in a single glance. Its intuitive dashboards are customizable, so you can create systems that work for you.

Well - I do not see anything in that tutorial that tells you how to put it on your Tomcat server - unless if something from the automatic things do it.

PS: YOu do not use double : before the port, right?

No just a single :
that must be what it refers to.
