Cool, right? I didn't need to code anything at all—I spent more time coming up with the text in the window above than in creating the window itself. Since it's a module, like any other module in NetBeans IDE, I can put it in an e-mail and send it to whoever I like who can then install it through the NetBeans Update Center. In other words, this is a fantastically effective yet incredibly simple way of educating the masses about whatever cool technology lies closest to your heart (or wallet).
By the way, the web.xml content in the screenshot above was generated using the code provided in yesterday's blog entry. In other words, I didn't type anything in the Source Editor, but as you can see in the screenshot, there's a servlet declaration and the welcome file is not a JSP file (as it would be in the web.xml file provided by the default NetBeans web application template), but an HTML file. Check out yesterday's blog entry if you're also tired of filling out web.xml by hand.
