The Hello World portlet that we’ll discuss in this section is same as the one in chapter 1, except that this version will use Spring Portlet MVC and will demonstrate what you need to do to create a portlet using Spring Portlet MVC.
Because the Hello World portlet uses Spring-specific JAR files, you can either download the Spring 3.0 release JAR files from the SpringSource website (http://www.springsource.org/download) or you can import the ch7_HelloWorld Eclipse project from the source code that accompanies this book.
