Select 3.0 as Dynamic web module version, which buys us ease of development by using the Servlet 3.0 specifications, and also leave the EAR membership checkbox unselected.

Click on Finish to continue.

Now let's add a quintessential servlet to our project that merely dumps a HelloWorld message. From the File menu, select New | Servlet and enter a meaningful...
