Struts 2 In Action Sample Application **Contents of the Sample Code Download** This download contains two web applications. These are contained in the two WAR files: Struts2InAction.war and HelloWorld.war. The first of these is the sample application for the entire book. The second is a special version of the HelloWorld Struts 2 application that can be used as a Struts 2 skeleton. It contains nothing but the Struts 2 HelloWorld code, from Chapter Two, and the minimal set of Struts 2 resources. While HelloWorld.war provides a convenient example of a minimal Struts 2 application, Struts2InAction.war represents the actual sample code of the book. This modularized application contains all of the sample code for the entire book, including the full featured Struts 2 Portfolio. This single Struts 2 web application actually contains a number of sub-applications. Struts 2 applications, modularized each with their own configuration files, JSP directories, and Java package space. These modular applications basically map to the different chapters of the book. The text of the book always takes pains to point you to the right application. The home page of the application as a whole has links to the various sub-applications which pertain to the different chapters. Note, the first eight chapters have their complete Java source contained within chapter specific packages, such as manning.chapterFour. The latter chapters, starting with Chapter 9, follow this pattern, but share a higher level package called manning.utils. Earlier chapters have their own version of utils, such as manning.chapterFour.utils. This shouldn't matter to you, but it might be a bit confusing if you don't know. **Purpose of the Sample Application** This sample application aims to provide a thorough and clean demonstration of all of the core features of the Struts 2 framework, and also provide a real world case study of a full featured Struts 2 application. The version of the sample application pertaining to each chapter of the book attempts to focus the sample code on the lessons at hand. After the introductory HelloWorld sub-applications, a full featured application will be developed incrementally through out the course of the book. This application, the "Struts 2 Portfolio", will increase in complexity with each chapter's contributions. Nonetheless, the focus of a given chapter's sample code will be on the topics of that chapter. When you start the book, the sample application will be rudimentary and incomplete. The only purpose of early versions is to make the demonstration of the early core topics unclouded by advanced topics such as Spring integration or CRUD actions. But by the latter chapters, one can expect that the correspondent version of the Struts 2 Portfolio to be quite full featured. Though you might still have to "flip" back to the Chapter Eight version to see how to integrate Ajax with a custom Result. **Sample Application Project Structure** While many people believe that their build and development process may be standard, there will always be others who believe another set of tools and practices, the ones they use, are more standard. We have decided to to keep this samplecode build tool and development process independent. The sample code that you will find zipped with this document is a ready to deploy war file. It contains all the jar files that it depends on and even contains its full source code. If you would like to promptly break this apart into an Ant or Maven project structure, feel free -- we certainly would! All of the source is located in a 'src' directory inside the web application's WEB-INF folder. This 'src' folder also contains other resources such as configuration files and properties files. However, the web application comes fully built and ready to roll. **Setting up the Application** There are a few details to attend to if you want everything to run smoothly out of the box. Database: Latter chapters use the Java Persistence API to implement the data layer. As it stands, this is configured to run with MySQL with a certain username and password. Configuration of this database connection information is found entirely at /WEB-INF/applicationContext.xml -- this Spring configuration file. The early versions of the application will probably still run in the face of a lack of database connectivity, though you will certainly see errors in the logs. JPA can pretty much run with any database you might have, so configuring this shouldn't amount to much. If you choose another database than MySQL, you'll need to get a driver. In all cases, you'll need to set up the db account and give it the right privelages. Filesystem Path: Another bit of configuration is the path to the file system location for writing uploaded images. This is set in several places. For early chapters, you can set this in the sub application's struts.xml file, for example in Chapter 6's /WEB-INF/classes/manning/chapterSix/chapterSix.xml file. The setting is located in the declaration element for the ImageUpload action. In these chapters, we just write the images to a directory relative to the server itself. Starting with chapter nine, we will set the value of the path with Spring. This can be set in the Spring applicationContext.xml file on the bean declaration element for the portfolioService. Now, the application will store the uploaded images in an images directory of the web app's doc root. You'll need to change this if you want Chatpers Nine and up to work. Default User Accounts: You will want to log in to the sample application for demoing various features. In chapters 1-8, you can use one of several built-in accounts. All of these can be seen by looking in that chapter's PortfolioService class. This class will be in the util package, such as manning.chapterThree.utils.PortfolioService. The built-in accounts can be seen in the static init block that defines the Map of users. You can always count on the Arty/password (username/password) account.
