AngularJS – Single Page App with RESTful APIs & Spring MVC
The article presents recipe to create single page application with AngularJS & Spring MVC where different pages are required to do transactions with server using RESTful API.

AngularJS – Post Data with ngResource, RESTful APIs and Spring MVC
The article presents concepts and some take-away code samples for developers wanting to POST data to RESTFul APIs using ngResource ($resource) service with SpringMVC on server side. The demo for this example could be found on this page, http://hello-angularjs.appspot.com/angularjs-restful-apis-post-method-code-example. The primary reason why I loved this approach rather than using $http service is the fact that using ngResource allows you to have abstraction such as a $resource class & its instance on which you have action methods to interact with RESTful APIs. It makes it quite easier to work with RESTful integration. On $resource class object, one could directly call action methods such as get, save. However, on …

Spring MVC Web.xml & Spring-Servlet.xml – Code Example
The article presents information around two key configuration files and code samples that one could pickup, put in their web application folder and get up and running. What & Why Web.xml? Web.xml is a deployment descriptor file. Simply speaking, see web.xml as a file used to describe classes, resources and configurations which is used by web server to serve the requests. As the request reaches to the web server, the server uses web.xml to map the URL of the request to the code that would handle the request. While working with Spring MVC, the server, in turn, delegates the request to DispatcherServlet which retrieves appropriate controller that would be used …
