LOTD #2: Phobos - MVC framework based on JavaScript

Phobos is a lightweight, scripting-friendly, web application environment running on the Java platform. It provides a complete MVC framework where Controller is a JavaScript class, View is an Embedded JavaScript (EJS) file and Model is typically a mix of Java and JavaScript.

The tech tip explains how Phobos and jMaki can be used to create a simple Ajax-enabled application using NetBeans tooling and GlassFish for deployment.
Another application built using Phobos and jMaki was shown in JavaOne 2007 technical keynote.

JavaScript Everywhere - Detailed Instructions

These are detailed instructions for this screencast.

Pre-requisites

  1. Download GlassFish v2 latest build.
  2. In NetBeans 5.5 or NetBeans 5.5.1 Update Center, manually download and install the Ajax Update Center module. Run the Update Center and install all the modules supported by Ajax Update Center plug-in. This will require an IDE restart.
  3. In NetBeans menu, go to Tools, Palette Manager, Add jMaki Component Library and then add jMaki Charting widgets.

Instructions

  1. Create a new NetBeans "Scripting" category and "Phobos Application" project. In CSS layout, scroll to the bottom and select "Two Fixed Right Sidebars" layout.
  2. In the 'Top Right Column', clear the text and drag/drop Yahoo Calendar widget.
  3. In the 'Right Column', clear the text and drag/drop BlockList.
    1. Replace

      value : [
      {title : 'jMaki Project Home', link : 'https://ajax.dev.java.net', description : 'Where to go for the latest jMaki.' },
      {title : 'jMaki Widgets Home', link : 'https://widgets.dev.java.net', description : 'The source for the latest jMaki widgets.' },
      {title : 'jMaki-Charting Home', link : 'https://jmaki-charting.dev.java.net', description : 'Enables complex charts rendered on the client in any modern browser.' }
      ]


      with

      service : "/xhp?id=rss"
  4. In Left Column, clear the text drag/drop Yahoo Tabbed View.
    1. Replace "content: 'Some Content'" with "url: '/tab1/show'".
    2. Replace "content: 'Tab 2 Content'" with "url: '/tab2/show', iframe: true".
  5. Right click on View, select New, Stylized Phobos View and name it tab1. In CSS layout, scroll to the bottom and select "No CSS style". This will automatically create a controller tab1.js which can be seen in the controller sub-tree. This demonstrates that a new controller is automatically created for every newly created view.
  6. Create tab2 using the instructions in the previous step.
  7. In tab1.ejs, clean all the text and drag/drop jMaki Line Chart widget from the palette.
    1. Change 'Months' to lineChartModel.xAxisTitle.
    2. Change the value of xAxis.labels to lineChartModel.xAxis.
    3. Change 'Temperature' to lineChartModel.yAxisTitle.
    4. Change the value of yAxis.tickCount from 3 to 10.
    5. Change the value of value.data to lineChartModel.chartData.
  8. In tab2.ejs, clean all the text and drag/drop Google Search widget from the palette.
    1. Edit Static Content, resources, google, search, widget.json and add

       
  9. In 'controller', 'tab1.js', replace model definition

    model = {
        name = "app name"
        };

    with

    var lineChartData = module.application.generateChartData();
    lineChartModel = { xAxisTitle: "Month",
              yAxisTitle: "Bug Count",
              xAxis: "['November', 'December', 'January', 'February', 'March', 'April']",
              chartData: lineChartData
            };
  10. In 'module', 'application.js', add the following code after onShutdown() function:

    this.generateChartData = function() {
      var chartData = [];

      var chartDataRow = this.getData('red', 'P1');
      chartData.push(chartDataRow);

      chartDataRow = this.getData('orange', 'P2');
      chartData.push(chartDataRow);

      chartDataRow = this.getData('yellow', 'P3');
      chartData.push(chartDataRow);

      chartDataRow = this.getData('green', 'P4');
      chartData.push(chartDataRow);

      return chartData;
    }

    // get bug data for a priority and assign a color to it
    this.getData = function(color, priority) {
      var chartDataRow = {};
      chartDataRow["color"] = color;
      var priorities = [];

      for (var k=180;k > 29; k=k-30) {
        var val = new Packages.mypkg.BugQuery().getNewBugList(priority, k);
        priorities.push(val);
      }
      chartDataRow["values"] = priorities;

      return chartDataRow;
    }
  11. Right click on Project, select Properties, Run tab, Add Jar/Folder, then add this library. This jar file manifests an existing Enterprise application and queries bug tracking system in this case.
  12. Right click on Project, select Run Project.

jMaki Phobos made-for-each-other

If you could not attend JavaOne 2007 last week and would like to know how jMaki and Phobos are made-for-each-other, then watch this excerpt of the technical keynote (start @ 1:02 and finish @ 6:26). You'll hear me presenting :-)

A complete detailed screen cast on how to build this demo is available here. I plan to post written instructions soon as well.

JavaOne 2007 - Day 1 Finished

After attending the keynote session, and getting ready for the technical keynote demo on JavaScript Everywhere! jMaki on client, Phobos on server, performing the keynote demo (which I think went well) and talking to many of you, alternating between booth #953 and booth #966 in the Pavilion, the day concluded with a Sun-only party at the third floor of W Hotel. Here are some pictures of movers and shakers at Sun. You'll see pictures of Rich Green, James Gosling, John Gage, Karen Tegan Padir and many others.

Tomorrow, I and Harold will be presenting on TS-4865: Takes Two to Tango (Wed 4:10 pm and Fri 1:30pm). See you there!

Thanks to Jeet for arranging the drinks in a timely manner, always a great resource and knows how to keep his team happy :)

Screencast #Web1: JavaScript Everywhere! JavaOne 2007 Demo

Developing a Web 2.0 app is really simple with Phobos and jMaki. Phobos is a light-weight scripting-friendly web application environment that runs on Java platform. jMaki is an Ajax framework and also provides a unified data model by wrapping components from existing toolkits such as Yahoo and Dojo.

Currently the primary language supported by Phobos is JavaScript and jMaki has support for Java, Phobos, PHP, and Ruby. Using the same language, JavaScript, on both client and server eliminates the impedance mismatch between the data format. Both of these technologies can be installed as plug-in modules in NetBeans IDE.

If you are attending JavaOne 2007, TS-6381 (Tue, May 8, 4:40 pm) and booth #953 in the Pavilion shows how easy it is to build a "Developer Dashboard" that allows you to monitor different activities of your project. If you want to build this application, then you can follow the screen cast.

Enjoy it here!

Three key points to be highlighted in this demo:

  1. jMaki and Phobos are made-for-each-other. They allow to use same skill set (JavaScript) on both client and server and eliminates the impedance mismatch by using the same data format on both the sides.
  2. NetBeans IDE provides a rapid development, run and test cycle increasing your development time. There is no deployment or compilation required.
  3. All these apps can be deployed on GlassFish V2 or V3, an open-source, production quality, and Java EE 5 compatible application server.
