wildfly-as-dashjs-html5-mobile: Example Application Using Multiple HTML5, Mobile & JAX-RS Technologies

Author: Charles Ott Level: Intermediate Technologies: CDI, HTML5, REST, JPA, DASH, MP4Parser Summary: Based on wildfly-as-dashjs-html5-mobile, but uses HTML5, making it suitable for mobile and tablet computers Target Product: WildFly Source: https://github.com/charlescva/

What is it?

Modern HTML5 mobile UI, allowing the storage and DASHing of static video content. Multiple bitrates is supported using more than one input file, seprated with semi-colons.

System requirements

Ultimately, this project depends on the Castlab's dashencrypt project, listed as a dependency in the pom. This can be downloading, compiled and installed in to your local repo from https://github.com/castlabs/dashencrypt

You also need Java 7.0 (Java SDK 1.7) or better, Maven 3.1 or better.

The application this project produces is designed to be run on JBoss WildFly.

An HTML5 compatible browser such as Chrome, Safari 5+, Firefox 5+, or IE 9+ are required. and note that some behaviors will vary slightly (ex. validations) based on browser support, especially IE 9.

Mobile web support is limited to Android and iOS devices. It should run on HP, and Black Berry devices as well. Windows Phone, and others will be supported as jQuery Mobile announces support.

With the prerequisites out of the way, you're ready to build and deploy.

Deploying the application

First you need to start the JBoss container. To do this, run

$JBOSS_HOME/bin/standalone.sh

or if you are using windows

$JBOSS_HOME/bin/standalone.bat

Note: Adding "-b 0.0.0.0" to the above commands will allow external clients (phones, tablets, desktops, etc...) connect through your local network.

For example

$JBOSS_HOME/bin/standalone.sh -b 0.0.0.0 

To deploy the application, you first need to produce the archive to deploy using the following Maven goal:

mvn package

You can now deploy the artifact by executing the following command:

mvn wildfly:deploy

The client application will be running at the following URL http://localhost:8080/wildfly-as-dashjs-html5-mobile/.

To undeploy run this command:

mvn wildfly:undeploy

You can also start the JBoss container and deploy the project using JBoss Tools. See the Getting Started Developing Applications Guide for more information.

Minification

By default, the project uses the wro4j plugin, which provides the ability to concatenate, validate and minify JavaScript and CSS files. These minified files, as well as their unmodified versions are deployed with the project.

With just a few quick changes to the project, you can link to the minified versions of your JavaScript and CSS files.

First, in the /src/main/webapp/index.html file, search for references to minification and comment or uncomment the appropriate lines.

Finally, wro4j runs in the compile phase so any standard build command like package, install, etc. will trigger it. The plugin is in a profile with an id of "minify" so you will want to specify that profile in your maven build.

NOTE: You must either specify the default profile for no tests or the arquillian test profile to run tests when minifying to avoid test errors. For example:

#No Tests
mvn clean package wildfly:deploy -Pminify,default

OR

#With Tests
mvn clean package wildfly:deploy -Pminify,arq-wildfly-remote

Running the Arquillian tests

By default, tests are configured to be skipped. The reason is that the sample test is an Arquillian test, which requires the use of a container. You can activate this test by selecting one of the container configuration provided for JBoss.

To run the test in JBoss, first start the container instance. Then, run the test goal with the following profile activated:

mvn clean test -Parq-wildfly-remote

Running the QUnit tests

QUnit is a JavaScript unit testing framework used and built by jQuery. This application includes a set of QUnit tests in order to verify JavaScript that is core to this HTML5 application. Executing QUnit test cases is quite easy. First, make sure the server is running and the project has been deployed as some of the tests will be testing the functionality of the services. Then, simply load the following HTML in the browser you wish to test.

<project-root>/src/test/qunit/index.html

For more information on QUnit tests see http://docs.jquery.com/QUnit

Importing the project into an IDE

If you created the project using the Maven archetype wizard in your IDE (Eclipse, NetBeans or IntelliJ IDEA), then there is nothing to do. You should already have an IDE project.

Detailed instructions for using Eclipse / JBoss Tools with are provided in the Getting Started Developing Applications Guide.

If you created the project from the command line using archetype:generate, then you need to import the project into your IDE. If you are using NetBeans 6.8 or IntelliJ IDEA 9, then all you have to do is open the project as an existing project. Both of these IDEs recognize Maven projects natively.

Downloading the sources and Javadocs

If you want to be able to debug into the source code or look at the Javadocs of any library in the project, you can run either of the following two commands to pull them into your local repository. The IDE should then detect them.

mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc
