In this chapter you have learned the importance of having a solid build system in place and the basics of the Ant build tool. We crafted a reusable Ant build to automate the building process of the TechConf system by using several open source Ant tasks. The resulting base build reflects my experience building many Java and J2EE applications. You can apply most of the ideas used in this system to your existing and future projects. In the rest of the book we will continue to enhance the build to create the J2EE components and artifacts that compose the sample application. The power of a well-crafted build will become even more apparent when we combine the building blocks learned in this chapter with the power of unit testing ( 8) and continuous integration ( 9).

The application you re going to develop in this chapter will be a text analyzer. Your Ruby code will read in text supplied in a separate file, analyze it for various patterns and statistics, and print out the results for the user. It s not a 3D graphical adventure or a fancy web site, but text processing programs are the bread and butter of systems administration and most application development. They can be vital for parsing log files and user-submitted text on web sites, and manipulating other textual data. Ruby is well suited for text and document analysis with its regular expression features, along with the ease of use of scan and split, and you ll be using these heavily in your application.

This can also be a reference to a static external file, a reference to the URL of a service that can generate XAML, or a reference to a named script block on the page that contains XAML. The second parameter is the onerror parameter that defines a JavaScript block on the page to call in case the Silverlight application throws an error. The third parameter, background, defines the background color for the control should it not define one already. The fourth parameter, minRuntimeVersion, is used by Silverlight to control the version of Silverlight that is, at minimum, needed to execute your application. So, for example, if your application doesn t use any of the features specific to Silverlight 3, you can specify the Silverlight 2 build version here (as in the listing), and users will not be prompted to upgrade to Silverlight 3 upon seeing your content. The fifth parameter, autoUpgrade, when set to true, will automatically upgrade Silverlight to the newest version upon instantiation. When set to false nothing will happen.
