Hi Kanak, Answers to the questions are as follows.
1. Hawtio[8] is a lightweight and modular[8] HTML5 web console with lots of plugins for managing your Java stuff. Plus it also has good documentation and community (tutorial) than other dashboards and portals. · various options for running hawtio o Chrome Extension o executable jar o under Application Server o stand alone Java application · Predefine API and plugin that can help on the building dashboard[9] · Rest API exploring Supporting[10]: Endpoint browsing (Swagger support for rest APIs) · Server Side Plugins in hawtio will help to get server side JVM details (Nodes) to UI (need to try some existing sample for this) · hawtio is a single page application, so much better for a dashboard. · It is highly modular and capable of dynamically loading plugins (JavaScript Libraries) *Some JS libs I will use* · AngularJS Directives and angularjs API (Below I have given few things to know to go for it) · bootstrap API (Mainly for UI css, It is a front-end framework for faster and easier web development) · d3 API (chatting) · ng-grid API (Grid/Template purpose) · javascript API (web support - used all time ) · icons from Font Awesome (basically for ICONS) Need go through some codes in here[14] regard to UI of hawtio-web I am planning to check some pluggings that had done for jclouds[11] from hawtio. As it has the same requirements and those will be full filled, This is also one reason to pick hawtio as there are a lot people that have used it. Some have our same requirements so those have done in here. Thus it is possible to achieve it. *Here is reason for AngularJS importance in hawtio* AngularJS[1] is a toolset for building dynamic views in web-applications. It supports extend HTML components. It is quick to develop (Model-View-Controller design pattern) as lot of things are predefined and clear API[2]. eg: · Think some those more help full to give better user experience on UI dashboard. · 'ngDblclick' allows you to specify custom behavior on a dblclick event. · 'ngController' attaches a controller class to the view · few that can help more user experience on dashboard 'ngShow', 'ngMouseenter' · For future work 'ngTouch' for touch device also can be used and the same dashboard can be improved over multiple devices. *Some dashboard and portal servers, that I researched.* · JavaScriptMVC[3] is a JavaScript framework for lightweight applications developing and easily maintainable framework. jQuery supports. Not much easy access for JVM. · Backbone.js[4] gives structure to web applications. It provides custom events binding facilities plus event handling. It connects existing API over a RESTful JSON interface. (JVM limitation plus Java API incompatibilities ) · jPorta[5] is a fully functional portal engine, It use Gadget, JSP page. (Not powerful API and docs) · jetspeed[6] supports web browser and can be considered as central hub where information from multiple sources are made available in an easy to use manner. It is mainly for XML portal and not for dashboard UI stuff. · jPortlet[7] different modes of viewing such as VIEW, EDIT, CONFIGURE or HELP. It have Skinnable look & feel (No much documentation or clear APIs) · I Read some on Portlet Specification[7] to get some basic idea on java portal concepts. [1] http://angularjs.org/ [2] http://docs.angularjs.org/api [3] http://javascriptmvc.com/ [4] http://documentcloud.github.io/backbone/ [5] http://jporta.sourceforge.net/ [6] http://portals.apache.org/jetspeed-1/ [7] https://www.jcp.org/en/jsr/detail?id=168 [8] http://hawt.io/plugins/index.html [9] http://hawt.io/plugins/dashboard/ [10] http://hawt.io/plugins/api/ [11] http://hawt.io/plugins/jclouds/ [12] http://hawt.io/plugins/jboss/ [13] http://hawt.io/plugins/karaf/ [14] https://github.com/hawtio/hawtio/tree/master/hawtio-web/src/main/webapp/app/ui 2. I would like an explanation on the architecture of helix or a diagram explaining the Helix Architecture. Also if you can point where the relevant code of REST json, JVM api and CLI appears in Helix source code it would be much useful. If you can share with me some sample code to try or any diagram related it would make my work easy. Here are some DOC I am referring[1], are those up to date or much better tutorial that will be helpful for me to understand helix core and API -Helix API (Java API, REST, CLI) scope is there? or grouping and limitation over each APIs Helix Controller[2] implementation. [1] http://helix.apache.org/apidocs/reference/packages.html [2] http://helix.apache.org/0.6.3-docs/tutorial_controller.html Could you give me a good introduction to Helix. Also some sample code that I can try to get exposed to REST API, CLI and some sample code / tutorial to practice Java API & Interface would be much help. 3. I'm in my final year at University and don't have any other commitments and projects going on at the moment. My previous programming experience include mainly Microsoft Technologies (Visual Studio / MS Server / C# / ASP.NET). Several of those projects included Crystal Reports as A Reporting Tool. Thus as a component of HCI I'm familiar with Reporting Tools. Since I have not much experience/exposure to open source and industrial exposure of java I decide on applying for GSOC with the intention that it will broaden my horizons giving me advantage over my colleagues when applying for jobs after the exams. Therefore I find it a refreshing new experience to interact with the open source community and to contribute to it.
