Assuming we accept the statement that all software systems must and will change over time, and also assuming that we all want our code to remain crisp, clean, and uncluttered of quick-and-dirty patches to accommodate the customer request du jour, how do we reconcile these conflicting requirements Refactoring is the answer! Refactoring, as defined by Fowler, is the restructuring of software by applying a series of internal changes that do not affect its observable behavior (Fowler 1999) Refactoring is one of the primary duties in agile methodologies such as eXtreme Programming How can we facilitate constant refactoring of our code Some of the key ways this can become easier is to have coding standards, simple design, a solid suite of tests, and a continuous integration process (Beck 1999).

package auction.beans; import ... public interface EditItem { // Value binding methods public Long getItemId(); public void setItemId(Long itemId); public Item getItem(); // Action binding methods public String doSearch(); public String doSave(); // Cleanup routine public void destroy(); }

In an eXtreme Programming team, the names of the refactorings replace type code with strategy can become as commonplace as design patterns such as the strategy pattern Fowler s definitive Refactoring book provides a catalog of refactorings and when and how to apply them, just as the Gang of Four book (Gamma et al 1995) is the definitive guide to design patterns We are not going to tell you how you should write your Java programs; instead, we refer you to some of the books in the Bibliography, such as The Elements of Java Style (Vermeulen et al 2000) and Bloch s Effective Java (2001) These should be on the desk of every Java developer We address Ant coding standards in appendix D.

The first two methods are the getter and setter for the value binding of the search input text field of the page. The getItem() method (you don t need a setter here) will be used later by the edit page. The doSearch() method is bound to the Search button, doSave() will be bound to a button on the edit page. This is an interface for a stateful component. A stateful component is instantiated when it s first requested for example, because a page is rendered for the first time. Every stateful component needs a method that the runtime environment can call when the component is destroyed. You could use the doSave() method and say that the component s lifecycle ends when this method completes, but you ll see in a minute why a separate method is cleaner. Next, let s look at the implementation of this interface. The EJB component implementation The standard stateful component in EJB 3.0 is a stateful session bean. The implementation in EditItemBean.java is a POJO class with a few extra annotations. In listing 17.9, all Seam annotations are shown in bold.

@Name("itemEditor") @Scope(ScopeType.CONVERSATION)

Just as good Java code should be simple, testable, and readable, your build file should be simple, testable, and follow coding standards; the XP methodology applies to build files and processes as much as to the Java source The remainder of this chapter is all about how to use Ant for testing Continuous integration is a topic that will be touched upon in this chapter, but covered in more detail in chapter 16..

@Stateful public class EditItemBean implements EditItem { @PersistenceContext EntityManager em;

A common way that many Java developers exercise objects is to create a main method that instantiates an instance of the class, and performs a series of checks to ensure that the object is behaving as desired. For example, in our HtmlDocument class we define a main method as

private Long itemId; public Long getItemId() { return itemId; } public void setItemId(Long itemId) { this.itemId = itemId; } private Item item; public Item getItem() { return item; } @Begin public String doSearch() { item = em.find(Item.class, itemId); if (item == null) FacesMessages.instance().add( "itemSearchField", new FacesMessage("No item found.") ); return item != null "found" : null; }

public static void main(String args[]) throws Exception { HtmlDocument doc = new HtmlDocument(new File(args[0])); System.out.println("Title = " + doc.getTitle()); System.out.println("Body = " + doc.getBodyText()); }

@End public String doSave() { item = em.merge(item); return "success"; }

We are then able to run the program from the command-line, with the proper classpath set:

@Destroy @Remove public void destroy() {} }

The Seam @Name annotation declares the name for this Seam component. It also turns this EJB into a Seam component. You can now reference this component anywhere under this name. When an instance of this component is required, Seam instantiates it for you. Seam puts the instance into a context under its name. Here s a formal description:

Using Ant as a Java program launcher, we can run it with the <java> task:
