<h3><span>JWt: an introduction</span></h3>

<p>JWt is a Java library for developing web applications.</p>

<p>The API is <b>widget-centric</b> and uses well-tested patterns of
desktop GUI development tailored to the web. To the developer, it offers
abstraction of web-specific implementation details, including client-server
protocols, event handling, graphics support, graceful degradation (or
progressive enhancement) and URL handling.</p>

<p>Unlike many page-based frameworks, JWt was designed for creating
stateful applications that are at the same time highly interactive
(leveraging techinques such as Ajax to their fullest) and accessible
(supporting plain HTML browsers), using automatic <b>graceful
degradation or progressive enhancement</b>. Things that are natural
and simple with JWt would require an impractical amount of effort
otherwise: switching widgets using animations, while being perfectly
indexed by search robots with clean URLs, or having a persistent chat
widget open throughout, that even works in legacy browsers like
Microsoft Internet Explorer 6.</p>

<p>JWt applications can be deployed in a standard Java Servlet
container.</p>

<h4>Interactive, secure and accessible</h4>

<p>Page-based web frameworks (JSP/JSF, Struts, Spring MVC, etc...)  do not
attempt to abstract underlying technologies (HTML/XHTML, JavaScript,
CSS, Ajax, WebSockets, Comet, Forms, DHTML, SVG/VML/Canvas). As a
consequence, a web developer needs to be familiar with all of these
evolving technologies and is also responsible for graceful degradation
when browser support is lacking. The structure of many web
applications still follows mostly the page-centric paradigm of early
day HTML. This means that not only will you need to implement a
controller to indicate how a user moves from page to page, but when
using advanced Ajax, you will need to design and maintain your
client-server communication.</p>

<p>Pure Ajax frameworks on the other hand require tedious JavaScript
programming to deal with browser quirks, and client-server programming
to interact securely with server resources. These applications usually
are not compliant with accessibility guidelines and cannot be indexed
by a search robot.</p>

<p>In either case, generating HTML code or filling HTML templates is
prone to security problems such as <a
href="http://en.wikipedia.org/wiki/Cross-site_scripting">XSS
(Cross-Site-Scripting)</a> by unwillingly allowing JavaScript to be
inserted in the page, and <a
href="http://en.wikipedia.org/wiki/Cross-site_request_forgery">CSRF
(Cross-Site Request Forgery)</a> by trusting cookies for
authentication. These security problems are hard to avoid by a
framework when as a developer you need to implement JavaScript
functionality thus the framework cannot filter it out.</p>

<p>In contrast, a web application developed with JWt is developed
against a Java API, and the library provides the necessary HTML/XHTML,
Javascript, CGI, SVG/VML/Canvas and Ajax code. The responsibility of
writing secure and browser-portable web applications is carried by
JWt. For example, if available, JWt will maximally use JavaScript and
Ajax, but applications developed using JWt will also function correctly
when JavaScript is not available. JWt will start with a plain HTML/CGI
application and progressively enhance to a rich Ajax application if
possible. With JWt, security is built-in and by default.</p>

<p>By using standard Java and JVMs, JWt applications can benefit from
any existing Java libraries and JVM features including its support for
your favourite scripting language.</p>

<h4>Typical use scenarios:</h4>

<ul>
  <li><b>High performance, complex web applications</b> (with a
    database backend) that require a responsive and dynamic user
    interface and benefit from the use of Java, if only to use Java
    refactoring tools while keeping track of ever changing
    requirements.</li>

  <li>Web applications which maximally benefit from modern browser
    capabilities but with <b>graceful degradation</b> to adhere to W3C
    accessibility guidelines and be search engine friendly.</li>

  <li>Porting of <b>Java desktop applications</b> to the web.</li>
</ul>

<h4>Some benefits of using JWt</h4>

<ul>
  <li>The library allows you to develop web applications much like you
    develop Java desktop applications, using your favourite JVM
    programming language, while benefitting fully from the powerful
    tools available for (Java) development such as flexible debugging
    and source code refactoring.</li>
  <li>There are no fragile string-based bindings of parameters in
    templates or XML files, nor do you need to implement tedious (and
    security critical) request/response controller logic.</li>
  <li>Just a library: no need for new conventions which imply behavior
    or requirements for organizing your source code.</li>
  <li>JWt applications have automatic fall-back for non-JavaScript
    browsers where possible, allowing you to create fully accessible
    applications, which benefit from Ajax where available.</li>
  <li>Optionally, use XHTML and CSS for layout and decoration.</li>
  <li>Generates standards compliant HTML or XHTML code.</li>
  <li>Portable, anti-aliased graphics optimized for web usage (using
    inline VML, inline SVG, HTML5 canvas or PNG images).</li>
  <li>Avoid common security problems since Wt has complete control
    over the presentation layer and proactively filters out
  <i>active</i> tags and attributes, does not expose business logic,
    and simplifies authentication using a stateful design.</li>
  <li>Ultra-fast load time and low bandwidth usage, which are affected
    only by screen complexity, not application size. Wt implements all
    the common tips and tricks for optimizing application
    responsiveness and even optimizes per browser.</li>
  <li>Integrates well with modern object relational mapping techniques such
    as the Java Persistence API (e.g. Hibernate).</li>
</ul>

  <message id="home.features">

<h3><span>Features</span></h3>

<h4>Core library</h4>

<ul>
  <li>Supports major browsers (Firefox/Gecko, Internet Explorer,
    Safari, Chrome, Konqueror, and Opera) but also plain HTML browsers
    (Links, Lynx).</li>
  <li>Simple deployment in standard Java Servlet 2.4 or 3.0 containers. </li>
  <li>No need for IDE plugins: it's plain old Java.</li>
  <li>Equal behavior with or without support for JavaScript or Ajax,
    as far as possible, by using graceful degradation or progressive
    enhancement.</li>
  <li>Efficient rendering and low latency.</li>
  <li>Support for browser history navigation (back/forward buttons and
    bookmarks), pretty URLs with HTML5 History if available, and
    search engine optimization with a unified behavior for plain HTML
    or Ajax sessions.</li>
  <li>Widget centric API that promotes component reuse and increases
    productivity.</li>
</ul>

<h4>Event handling</h4>

<ul>
  <li>Uses an event listener system for server-side event handling, 
    comparable to Java GUI frameworks (SWT, Swing).</li>
  <li>Listen for keyboard, mouse, focus and scroll events, and get
    event details (such as mouse position, modifier buttons, or
    keyboard key).</li>
  <li>Automatic synchronization of form field data between browser and
    server.</li>
  <li>Possibility to hook in custom JavaScript (e.g. for client-side
    only event handling), and <i>emit</i> Java signals from this
    custom JavaScript.</li>
  <li>Flexible Drag&amp;Drop API.</li>
  <li>Timed events and server-initiated updates ("server push"), the
    latter using Servlet 3.0 async features when deployed in a Servlet
    3.0 container.</li>
</ul>

<h4>Native painting system</h4>

<ul>
  <li>Unified painting API which uses the browsers native (vector)
    graphics support (inline VML, inline SVG, or HTML5 canvas).</li>
  <li>Supports arbitrary painter paths, clipping, text, images,
    transformations, drop shadow.</li>
</ul>

<h4>GUI components</h4>

See also the <a href="http://jwt.emweb.be/jwt-gallery/gallery">Widget
gallery</a> for an interactive overview of built-in functionality.

<h4>Built-in security</h4>

<ul>
  <li>Enables continuous use of HTTPS through low bandwidth
    requirements.</li>
  <li>Built-in Cross-Site Scripting (XSS) prevention. Rendered text is
    always filtered against potentially malicious code, making XSS
    attacks against JWt applications (close to) impossible.</li>
  <li>Not vulnerable to Cross-site Request Forgery (CSRF) because
    cookies are not needed for session tracking.</li>
  <li>Not vulnerable to breaking the application logic by skipping to
    a particular URL, since only those events exposed in the interface
    can be triggered.</li>
</ul>

<h4>Testing</h4>

With JWt, event handling code constructs and manipulates a widget
tree, which can easily be inspected by test code. Therefore, a <a
href="http://www.webtoolkit.eu/jwt/latest/doc/javadoc/eu/webtoolkit/jwt/WTestEnvironment.html">test
environment</a> allows your application to be instantiated and events
to be simulated in absence of a browser, short-cutting the underlying
request/response cycle that would otherwise require a simulated
browser.

<h4>Deployment</h4>
<ul>
  <li>Deploy into servlet containers (Tomcat, Jetty) and application
    servers (JBoss).</li>
  <li>Consists out of (currently four) jar files that need to be
    included in the IDE or used in war/ear archives.</li>
  <li>No XML, except for JEE's web.xml and message resource bundles.</li>
</ul>

    and <a
    href="http://www.webtoolkit.eu/jwt/latest/doc/javadoc/eu/webtoolkit/jwt/WTableView.html">WTableView</a> widgets for rendering a Model's

  <li>
    These item views have support for drag and drop of a selection of items.

<p>This example demonstrates the <a
href="http://www.webtoolkit.eu/jwt/latest/doc/javadoc/eu/webtoolkit/jwt/chart/package-summary.html">JWt
charting widgets</a> that are implemented on top of JWt's
cross-browser painting API. This painting API uses built-in browser
support for generating high quality graphics. Depending on the
browser, inline VML, inline SVG, HTML5 canvas or a PNG image is used
to render painted contents in a <a
href="http://www.webtoolkit.eu/jwt/latest/doc/javadoc/eu/webtoolkit/jwt/WPaintedWidget.html">WPaintedWidget</a>.
</p>

<p>This example also demonstrates how a Model can be shared by several
Views, and pass modification events to each connected View. The <a

<p>
  This example implements a GMail-like mail composer and shows among
  other things how to upload files asynchronously, showing a
  cross-browser upload progress bar and with support for multiple
  files.
</p>

<p>
  Some notes about this example:
</p>

  <ul>
    <li>
      The <i>ContactSuggestions</i> class provides auto-completion of
      the addressees in the To: Cc: and Bcc: fields. The widget
      derives from <a
      href="http://www.webtoolkit.eu/jwt/latest/doc/javadoc/eu/webtoolkit/jwt/WSuggestionPopup.html">WSuggestionPopup</a>.
    </li>
    <li>
      The <i>AttachmentEdit</i> widget uses a <a
      href="http://www.webtoolkit.eu/jwt/latest/doc/javadoc/eu/webtoolkit/jwt/WFileUpload.html">WFileUpload</a>
      to asynchronously upload one or more files. The upload <a
      href="http://www.webtoolkit.eu/jwt/latest/doc/javadoc/eu/webtoolkit/jwt/WProgressBar.html">progress bar</a> will work even in IE6.
    </li>
  </ul>
</div>
  </message>

 <message id="home.examples.chat">
<div>
<h4 class="example">Simple Chat</h4>

<p>
  <a href="http://jwt.emweb.be/jwt-simplechat/simplechat" class="run" target="_blank">
    <img src="/icons/orange-play.png" style="vertical-align: top"/> Run example
  </a>
</p>

<p>
  This example implements a simple chat client and server. Using
  <b>server-initiated updates</b>, you can easily push events from one
  user to other users. Server-initiated updates are implemented
  using Ajax long polling.
</p>

<p>
  When deploying in a Servlet-3.0 container, you can enable its
  asynchronous processing and JWt will benefit from this to not tie up
  threads for each open connection. But you can also deploy the
  application on a Servlet-2.5 container, reverting to blocking
  threads. This may be convenient when a Servlet-3.0 container is not
  available, e.g. during development.
</p>

<p>
  It also illustrates nice benefits of a class-based approach to web
  application development: you can easily instantiate the same widget
  class multiple times. The SimpleChatClient widget may be reused
  just as you reuse basic JWt widgets such as a push button.
</p>

<p>
  Interactive applications like these, which allow users to post HTML
  text to other users, are notorious for <b>cross-site-scripting (XSS)
  attacks</b>: a user enters malicious (javascript) code as part of
  his message. When another user renders this message, it may transmit
  unwanted private information retrieved from, for example, browser
  cookies. JWt prevents such attacks completely, and without any
  responsibility to the developer, since widgets such as WText ensure
  that what is displayed is only passive text, discarding anything
  that is not strictly text.

  Java applet.</p>

<p>
  In no more than 500 lines Java code, we rehashed the applet version

<h3><span>!Java ?</span></h3>

<p>You like the functionality, but do not grock Java for your project?</p>

<p>Do not despair. JWt exists in a native variant or through bindings
in other languages:

Leveraging the JVM's support for other languages, such
as <b>Clojure</b>, a LISP variant, Ralph Moritz is experimenting
with <a href="http://lispetc.posterous.com/hello-jwt-from-clojure">using
JWt from within Clojure</a>, documenting his experience in his blog
and eventually developing a small support library.

Albert Cervera i Areny is experimenting to use JWt from <b>Jython</b>,
another language running on the JVM. He documents how to create and run 
the "Hello World!" program in Jython in <a href="http://www.nan-tic.com/en/from-pyqt-to-jythonjwt-setting-up-the-environment">this blog post</a>.

If you prefer <b>C++</b>, you should consider
using <a href="http://www.webtoolkit.eu/wt">Wt</a>, the C++ version, which is developed and
maintained together with the Java version, and from which the Java
version is derived. It comes with application server included.

Richard Dale is
maintaining <a href="http://github.com/rdale/wtruby/tree/master">WtRuby</a>,
<b>Ruby</b> bindings to Wt, using the same framework used for generating Ruby
bindings to Qt and KDE.
