Sencha development using eclipse - Basic setups and folder sturcture

 Sencha touch is a OOP java script library used for creating HTML5 based mobile application, that run on mobile like Android, iPhone and Blackberry and give native app-work experience (Just like a JQuery Mobile).
 Use below link for downloading secha touch library. 

Sencha development - Basic folder structure.

1. Create a new web project using eclipse or STS.
2. Inside the web content folder, create a new folder called as 'sencha'.
3. Extract the sench library and copy the entire resources folder into 'sencha' directory.
4. Copy the 'sencha-touch-all.js' from Sencha library and put it into 'sencha' directory too.
5. Inside the web content folder, create one more  folder called 'app'. Inside into this folder, you have create model, view, controller, store and profile folders. Here only you need to put all your sencha related JavaScript files.
6. Inside the web content folder, just create the app.js and index.html file. These two files are starting point of the application.

The final structure should be like this.



7. Now I am going write simple code for getting simple alert. Just add the following code into app.js file.


Ext.application({
      name : 'SenchaDemo',
      launch : function() {
            alert("You have sucessfuly completed the basic setups of the sencha development");
      }
});



7. This is my html file, Here I have included all the necessary js and css files.


<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Sencha Basic Setup</title>
<link rel="stylesheet" type="text/css" href="sencha/resources/css/sencha-touch.css" />
<script type="text/javascript" src="sencha/sencha-touch-all.js"></script>
<script type="text/javascript" src="app.js"></script>
</head>
<body>
</body>
</html>

8. Deploy this application into any one web server like apache tomcat and open the inde.html page by using android or iphone with corresponding URL of the application. You should get alert like this.

Ext JS 4 – Creating web page using Ext.container.Viewport class and region propery

The Ext.container.Viewport is used for creating general web page and region property is used for splitting web page into different parts. Ext.container.Viewport is a specialized container represents the viewable area of the application (the browser area). It render itself to the document body, there is no need for providing renderTo property and it automatically sizes itself to size of the browser viewport. The viewport also re-size the child elements based on view area(based on browser width and height). The default layout of the viewport is border layout and we can customize this property according to our requirements. The viewport does not provide any scrolling. If necessary, the child elements(generally panels) within viewport needs to provide a scroll feature by using autoScroll property. See the below example for better understanding. This is Home.js file placed into app/view folder. Ext.define('MyApp.view.Home', { extend : 'Ext.container.Viewport&#

Simple Login Application Using Spring MVC and Hibernate – Part 1

 I hope developers working in web application development might hear about MVC architecture. Almost all technologies provide support for MVC based web application development, but the success is based on many factors like reusable of the code, maintenance of the code, future adaption of the code, etc..,  The success of the Spring MVC is “ Open for extension and closed for modification ” principle. Using Spring MVC the developers can easily develop MVC based web application. We don’t need any steep learning curve at the same time we need to know the basics of spring framework and MVC architecture. The Spring MVC consists of following important components. 1. Dispatcher servlet 2. Controller 3. View Resolver 4. Model Spring MVC - Overview  The overall architecture of Spring MVC is shown here.  1.
