Major Advantages Of GWT

On someone asked what the major advantages of GWT are. Here are some of the responses:

  • Both browser-side and servlet-side coding in Java
  • Single code base makes it both easy to develop and debug
  • Quite a mature technology now with big user community
  • Actively managed and being enhanced by Google
  • Easy integrations with other technologies, e.g., JSP and native JavaScript
  • Easy to embed GWT widgets in web pages
  • Handles most JavaScript cross-browser issues
  • Provides a lot of abstractions for client-server programming like GWT-RPC and RequestFactory
  • “I would say that Java tools, for example testing and packet management. Also it generates working javascript for mainstream browsers.”

    The new Firefox beta version 16 brings a command line to the browser.
    This may prove useful for developers. The command line provides keyboard access to the browser and tools. This first iteration is providing commands to do things that can be done with the Developer Toolbar or in Firebug or other tools, but if you prefer a keyboard to a mouse this holds a lot of promise. It will give you command completion and easy to use help for itself to get you up to speed. It will allow you to inspect, style, and debug JavaScript. You can also manage cookies, take a screenshot all from the keyboard.
