Proposal Title : Enhance Tuscany Widget Support

Apache Project Name : Tuscany 

Mentor Name : Luciano Resende (Pending Confirmation) 

Link To Project Idea JIRA : Enhance Tuscany Widget Support

Proposal Content Details :

Current Intentions

1. Code the file for implementation-widget-runtime-jquery

In the model of implementation-widget-runtime-pojo - Luks pretty easy!

Important classes and function

RuntimeComponent - correspond to the component tag in the xml? have to debug and check.

2. Add some kind of switch on the composite file to change the classpath dependencies

• ComponentJavaScriptGenerator.java contains

QName - This is used to identify different generators supporting different JavaScript frameworks. This is now present internally and configured as 

private static final QName NAME = new QName("http://tuscany.apache.org/xmlns/sca/1.1", "component.script.generator.dojo");

in DojoJavaScriptComponentGeneratorImpl.java

How can we bring it out and make it configurable in a composite file.

• WidgetImplementationProvider.java contains ( Line 94) 

The code to start dojo provider if added to the class path

• WidgetImplementationProviderFactory ( Line 51 ) - Utility function

3. Use the jQuery native ajax calls

Following are the popular ajax request present in jQuery \[1\]

• load(): Load a piece of html into a container DOM.
• $.getJSON(): Load a JSON with GET method.
• $.getScript(): Load a JavaScript.
• $.get(): Use this if you want to make a GET call and play extensively with the response.
• $.post(): Use this if you want to make a POST call and don’t want to load the response to some container DOM.
• $.ajax(): Use this if you need to do something when XHR fails, or you need to specify ajax options (e.g. cache: true) on the fly.
