The complete title for this JavaOne 2007 BOF was Ingredients for a Killer Application – Adding Mojo to Your Swing and Ajax Applications with Seamless Web Browser Integration. Wow, what a mouthful. It might not be immediately clear from the title but the focus of this BOF was the use of the JDesktop Integration Components<\/a> (JDIC) Web Browser embedded in a Swing application. As we all know Swing does not a complete Java-based web browser component, although there is a good XHTML Renderer<\/a>. With the JDIC you can embed a native browser (IE, Firefox, or Safari) in your Swing application. Unlike the XHTML Renderer, the native browser allows you to run JavaScript code, apply AJAX\/Web.2.0 effects, manipulate the DOM, and more.<\/p>\n

Integrating JDIC into your project is as simple as adding the jar. A key demonstration of this BOF was to show how to have bi-directional native browser communication with your Swing application. To use the JDIC native browser, just create a WebBrowser object and invoke the executeScript method passing some JavaScript code in a string to communicate from the JVM to the browser.<\/p>\n

To work your way from the broswer to the Java process you need to listen to the statusTextChange method on the WebBrowserListener. The statusTextChange method would be called when you set a string value to the browser window, as in the following JavaScript code.<\/p>\n

[source:javascript]
\nwindow.status = “message passed to the JVM”;
\nwindow.status = “”;
\n[\/source]<\/p>\n

The speaker did warn the audience that using the status text to listen for processing instructions from the browser was a total and complete hack. The speaker recommended that as soon set the status to communicate with the JVM that you clear the command\/message. The speaker talked about having your own mini-protocol to pass data and instructions to the JVM, I would recommend you use a standard like JSON<\/b>.<\/p>\n

Someone in the audience asked about having access to the x, y location of DOM elements in the browsers to combine with Java 2D overlays and effects, but the speaker was not sure how to go about implementing such a task.<\/p>\n

Using the JDIC native web browser in your Swing application you can take advantage of Web 2.0 services such as Google Maps and Flickr in a Swing\/Web 2.0 mashup<\/b>. I have been looking into the JDIC web browser so that I can create a offline standalone web-based application by embedding a browser, Jetty<\/a>, HSQLDB<\/a>, and JRuby on Rails. Embedding all these components is easy enough to integrate, although you might have to write some glue code to make into a fully stacked framework.<\/p>\n
