Angular (before hands on) -01

-
Here I'm mainly talking about angular 2. After AngularJS, angular2 is released with major changes in the Framework. Changes happened The major change was transferring to TYPESCRIPT from JS. And angular 2 is based on a Component service architecture. AngularJS had an MV* architecture. Let's take a look at the core features of this framework... Module : modules are used to separate the functionality of the application. When you create your initial angular application When you take a module code. (ex:- app.module.ts) there are imports, declarations, bootstrap and can see annotations too. import { NgModule } from '@angular/core' ; import { BrowserModule } from '@angular/platform-browser' ; import { AppComponent } from './app.component' ; @NgModule ({ imports : [ BrowserModule ], declarations : [ AppComponent ], bootstrap : [ AppComponent ] }) export class AppModule { } @NgModul...

I'm starting this series of posts about J2EE to get an idea of concepts about restful web service implementations using J2EE. Before we go into Restful web services lets see what is a web service first... Web service Did you ever think of when you are playing a game and it's asking you to post your score in your facebook wall? you don't need to go to the facebook to do so, the game itself gives the ability to post your score. That's how web services come in. Websites like Facebook twitter publish their API's on the web that another application can use. Think about what happens when you visit a website. how it differs with web services. When you want to visit, let's say Facebook, the client makes Http request to the server and the server will respond to the client by sending an Http request. that response is basically an HTML response. But when client call to a web service the response will be an XML/ JSON/ text whatever type of response. Rest web ser...
