   Line 3: The taglib directive tells the servlet container that this page will be using

the Struts 2 tags.

   Line 10: The s:property tag displays the value returned by calling the method

getName of the HelloWorldAction class. The getName method returns a String.

It is this String returned by getName that will be displayed by the s:property tag.

Now you will learn a different technique of declarative configuration provided by Struts 2:
annotations. You can create the new project or modify the project created earlier. Figure 4-13
illustrates the directory structure.
