HTML deployment
Standard Web server
If you aren't targetting mobile development (event when Nibiru Mobile has "mobile" in its name!), you can deploy it on an standard web server and run the app from a desktop browser.
Just compile and deploy it as you would do with any GWT application.We recommend you reading the GWT documentation regarding this aspect.
If you are targetting mobile development, you can even use a Web server + desktop browser in order to test quickly your application. You can even use GWT SuperDev mode in order to avoid full compilation when developing the application. Again, we recommend you reading GWT documentation related to this point. However, you can't test hardware-related fucntionality under a desktop browser (maybe geolocation is the exception, which is supported by some browsers).
Apache Cordova
In order to deploy to a mobile device (or a simulator), you must follow PhoneGap instructions for your platform. Typically, you will need creating a project for each platform and copying the GWT generated files inside each one.
