Because of many-to-many relationships between actions and JSP pages, web application becomes hard to maintain right from the start.</p> </section> <section id="codebehind"> <title>Struts Dialogs: code-behind and event handling</title> <p>Struts Dialogs makes development simpler by employing code-behind pattern similar to one used in ASP.NET framework, while keeping your investments into Struts.</p> <p>One of the ASP.NET concepts is the unity of page markup (ASPX) and business-related code (C# or VB). A page layout and widgets are defined in the markup, while page lifecycle and incoming events are handled by corresponding class file. This concept is especially easy to grasp for programmers of desktop applications:</p> <source> Before page is displayed, the code behind it initializes page data. After page is rendered, activating a widget in the browser window generates event, which is dispatched to a handler. defined in the class. </source> <p>This pattern is implemented by Struts Dialogs with no changes to core Struts classes or tag libraries. Moreover, it is improved, because Struts allows to define several markup pages corresponding to one Java class.</p> <p>To use event-dispatching actions one should think in terms of <em>web resources</em>. Internet is about web resources, not about mere pages. A page is just a visualization of a resource in its current state at a given time. An address identifies a resource, not a particular representaion of it. A resource can be rendered differently depending on its state.</p> <figure src="images/struts-dialog-action.gif" alt="Dialog action"/> <p>In Struts Dialogs each resource is represented by one action (which consists of an action class and a form bean). Depending on resource state, an action can render one view or another. Views, corresponding to an action, are defined as JSP pages. Each JSP page belongs to one action only, which is called a <em>parent action</em>.</p> <p>Submission of a form from JSP page generates input event, which is handled by the page's parent action. Action class defines handler methods for every input event. Input events can be generated not only by submitting a form (POST), but also by clicking on a command link (GET). Think of enhanced <code>DispatchAction</code>.</p> <p>Direct linking from JSP page to another resource is possible, but discouraged. Instead, a command link should generate an event, which would be handled by parent action class. It is up to an action class to decide where to navigate next. This approach allows to define all navigation targets in the <code>struts-config.xml</code> file, having a clear representation of web application structure.</p> </section> <section id="state_management"> <title>State management</title> <p>Struts Dialogs does not introduce new classes to manage application state. Instead, it uses existing ActionForm class as a first-class stateful input/output object. In JSF terms, ActionForm now acts as a backing bean for JSP page. There is nothing groundbreaking in using session scope for ActionForm, or in storing output data in it. Online poll shows that about 60% of respondents use ActionForm for queueing output data.</p> <p>With changing ActionForm scope to session, it is possible to initialize form bean only once, and to reuse data between requests. This is convenient for form resubmissions, for page reloading or for navigating back to previous resource. Having all resource data in a single ActionForm simplifies JSP page. Struts automatically populates ActionForm with submitted data on input phase, the same data can be used for presentation on render phase without additional efforts.</p> <p>Session scope justifies the usage of nested properties within ActionForm. It is easy and convenient to use business objects or DTOs as nested properties instead of copying their data to ActionForm and from ActionForm.</p> </section> <!-- <section id="components"> <title>Component Development</title> <p>Struts Dialogs library allows building <em>web components</em> using Struts and JSP.</p> <p><strong>Web component</strong> is a server-side object, which is:</p> <ul> <li>stateful;</li> <li>can process input events;</li> <li>can render itself according to its current state;</li> </ul> <p><strong>Web control</strong> is a web component, which:</p> <ul> <li>can be embedded into a <em>master page</em>;</li> <li>can interact with master page and, optionally, with other web controls.</li> </ul> <p><strong>Web dialog</strong> is a special case of a web component, which has only one corresponding view.</p> <p>If the above definition sounds too vague and generic, think of a standard login form. It asks a user for name and password. If entered information is incorrect, login form redisplays itself along with error message. Login form can render itself, it has only one view, and it is stateful, because if you reload login page, it retains username and password. Therefore, login form is an example of a <link href="http://www.superinterface.com/strutsdialog/logindialog.html">login dialog</link>.</p> <p>Now consider a component which not only collects username and password, but also displays user's login/logout status. It is more complex than a login dialog, because it maintains two states and two corresponding views: "not logged in" and "logged in". This is a <link href="http://www.superinterface.com/strutsdialog/logincomponent.html">login component</link>. After user successfully logs in, login component displays page corresponding to "logged in" state, which shows user information. Whenever logged-in user navigates to this component, the latter shows user's information.</p> <p>What if we want to embed login component in a complex web page? For example, see how it is done by CollabNet on <link href="http://www.java.net">www.java.net</link> website. There is a small login form in the upper right corner of the home page. After you log in, the content of the form changes and shows your login name and logout button. This login form, embedded into master page, is an example of <link href="http://www.superinterface.com/strutsdialog/logincontrol.html">login control</link>.</p> </section> --> <section id="actions"> <title>Actions</title> <p>Most features of the Struts Dialogs library are available through use of different action classes.
