class="mw-redirect" title="Web application framework">web application framework</a> for the <a href="/wiki/Java_(programming_language)" title="Java (programming language)">Java programming language</a> conceptually similar to <a href="/wiki/JavaServer_Faces" class="mw-redirect" title="JavaServer Faces">JavaServer Faces</a> and <a href="/wiki/Apache_Tapestry" title="Apache Tapestry">Tapestry</a>. It was originally written by Jonathan Locke in April 2004. Version 1.0 was released in June 2005. It graduated into an <a href="/wiki/Apache_Software_Foundation" class="mw-redirect" title="Apache Software Foundation">Apache</a> top-level project in June 2007.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Rationale">Rationale</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Apache_Wicket&action=edit&section=1" title="Edit section: Rationale"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Traditional <a href="/wiki/Model-view-controller" class="mw-redirect" title="Model-view-controller">model-view-controller</a> (MVC) frameworks work in terms of whole <a href="/wiki/HTTP_request" class="mw-redirect" title="HTTP request">requests</a> and whole pages. In each request cycle, the incoming request is mapped to a method on a <i>controller</i> object, which then generates the outgoing response in its entirety, usually by pulling data out of a <i>model</i> to populate a <i>view</i> written in specialized <a href="/wiki/Web_template" class="mw-redirect" title="Web template">template markup</a>. This keeps the application's <a href="/wiki/Control_flow" title="Control flow">flow-of-control</a> simple and clear, but can make <a href="/wiki/Code_reuse" title="Code reuse">code reuse</a> in the controller difficult. </p><p>In contrast, Wicket is closely patterned after <a href="/wiki/Stateful" class="mw-redirect" title="Stateful">stateful</a> <a href="/wiki/GUI" class="mw-redirect" title="GUI">GUI</a> frameworks such as <a href="/wiki/Swing_(Java)" title="Swing (Java)">Swing</a>. Wicket applications are trees of <i>components</i>, which use listener <a href="/wiki/Delegation_(programming)" class="mw-redirect" title="Delegation (programming)">delegates</a> to react to <a href="/wiki/HTTP" title="HTTP">HTTP</a> requests against links and forms in the same way that Swing components react to mouse and keystroke events. Wicket is categorized as a component-based framework. </p> <div class="mw-heading mw-heading2"><h2 id="Design">Design</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Apache_Wicket&action=edit&section=2" title="Edit section: Design"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Wicket uses plain <a href="/wiki/XHTML" title="XHTML">XHTML</a> for templating (which enforces a clear separation of presentation and <a href="/wiki/Business_logic" title="Business logic">business logic</a> and allows templates to be edited with conventional <a href="/wiki/WYSIWYG" title="WYSIWYG">WYSIWYG</a> design tools<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>). Each component is bound to a named element in the XHTML and becomes responsible for rendering that element in the final output. The <i>page</i> is simply the top-level containing component and is paired with exactly one XHTML template. Using a special tag, a group of individual components may be abstracted into a single component called a <i>panel</i>, which can then be reused whole in that page, other pages, or even other panels. </p><p>Each component is backed by its own model, which represents the state of the component. The framework does not have knowledge of how components interact with their models, which are treated as <a href="/wiki/Black_box" title="Black box">opaque</a> objects automatically <a href="/wiki/Serialization" title="Serialization">serialized</a> and <a href="/wiki/Object_persistence" class="mw-redirect" title="Object persistence">persisted</a> between requests. More complex models, however, may be made <i>detachable</i> and provide <a href="/wiki/Software_hook" class="mw-redirect" title="Software hook">hooks</a> to arrange their own storage and restoration at the beginning and end of each request cycle. Wicket does not mandate any particular object-persistence or <a href="/wiki/Object-relational_mapping" class="mw-redirect" title="Object-relational mapping">ORM</a> layer, so applications often use some combination of <a href="/wiki/Hibernate_(Java)" class="mw-redirect" title="Hibernate (Java)">Hibernate</a> objects<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="Hibernate default flush mode is auto-flush, most screens are stateless (May 2019)">citation needed</span></a></i>]</sup>, <a href="/wiki/EJB" class="mw-redirect" title="EJB">EJBs</a> or <a href="/wiki/POJO" class="mw-redirect" title="POJO">POJOs</a> as models. </p><p>In Wicket, all server side state is automatically managed. You should never directly use an HttpSession object or similar wrapper to store state. Instead, state is associated with components. Each server-side page component holds a nested hierarchy of stateful components, where each component's model is, in the end, a POJO (Plain Old Java Object) </p><p>Wicket aims for simplicity. There are no configuration files to learn in Wicket.
