From Portlets to OpenSocial Gadgets to Progressive Web Apps: Part IIv

Implementation Generation with Java

The concept of ultra-modern Revolutionary Web Apps is outstanding because it saves you writing native apps for every operating gadget. Growing apps for distinctive goal systems are highly priced. Nonetheless, in some cases — as a minimum for the time being — we want to build local apps. For this purpose and to keep resources, there is the so-known as Hybrid Software Development Global Amend. There are the latest Hybrid Utility Frameworks with HTML Consumer interfaces accessible.

The problem with this technique is that the HTML UI does no longer feel definitely local. Therefore, there is a 2d contemporary Hybrid Software the so-known as Hybrid Software Framework with local UI. In this example, you use the native UI in each running machine and use e.G. The equal programming language to cover the rest. As Java remains the primary programming language, it’s miles sensible to base your platform strategy on Java. The image below suggests comparing Modern Net Apps, Hybrid Applications with HTML UI, and native UI in runtime. evaluation Progressive Web Apps – Hybrid Apps with HTML UI – Hybrid Apps with native UI

What contemporary tools and merchandise does Java offer us to put in force the Era above?


Spring Boot and Spring Cloud for the Microservice Structure. Those Open Source merchandises are, without a doubt, mature, manufacturing prepared, and clean to use.

Net Apps Primarily based on Innovative Web Apps.

For this cutting-edge Internet app, you do not have state-of-the-art options in Java place. A framework like JSF or Grails cannot truly impose this selection because you want JavaScript, which has to run at the browser aspect. Using natural Java instead of adding complexity in JavaScript with frameworks like AngularJS could be a plus. For this reason, you could pick the following merchandise:

GWT – That is still the best Java to JavaScript Open Supply transpiler.

Jsweet – A transpiler from Java to TypeScript/JavaScript. ST-JS (Strongly Typed JavaScript) – A transpiler from Java to JavaScript, pretty just like sweets. Jsweet has exceptional mechanisms state-of-the-art transformation of the Java codes to JavaScript from GWT in view that sweet brand new modern it’s very own Java libraries to manage the transformation.

Team: A transpiler from Java bytecode to JavaScript.

DukeScript: A framework to create JavaScript Application Based totally on Java. Commonly, DukeScript can speak without delay from Java to JavaScript code. DoppioJVM: A Java Digital System is written in a hundred% JavaScript. The idea is to run Java apps inside the browser with this Virtual Machine. Java2Script Bridge RCP to RIA: A converter modern-day Eclipse SWT to JavaScript. GWT is the most mature product in this class, and Google uses GWT in state-of-the-art products. GWT may be included with the following UI frameworks:

Bootstrap (GWTBootstrap3),

  • Fabric Design (GWT Fabric Design),
  • Cloth Design with Polymer.
  • The future model state-of-the-art GWT can also work with Angular 2 (Angular2Boot).
  • There may be a group of brand new quality practices on how to use GWT to put into effect Progressive Web Apps so that you can write Innovative Net Apps nowadays absolutely in Java with GWT.

local Apps With HTML UI

Using GWT and GWT PhoneGap with skins cutting-edge Android and iOS: With the equal Generation Java, GWT, and PhoneGap / Apache Cordova, you could write a native app with HTML UI. instead of Using this Generation, you perhaps must use Revolutionary Web Apps Generation in view that HTML UI does not look local besides. Modern Net App is simply equal, and you could write it as soon as for Internet and mobile.

Native Apps With native UI

In Android, you can implement the native UI simply. The use of Java; no unique workaround is needed. In iOS, you want to use Objective-C to put in force the local UI. Using Open Supply product like J2ObjC (Java to Goal-C transpiler) will help loads to reuse the Java codes A product like Google Inbox use GWT and J2ObjC to deliver the identical functionalities throughout operating structures (Internet, Android, and iOS) at the equal time.

Platform strategy

So how are we able to outline our platform method today? The following points are my summary:


Suppose you use Java as your programming language, leverage Spring Boot and Spring Clouds on your Microservice Structure implementation. But in the end, you could use specific implementation technology like Java. Net, and others. It’s miles simply crucial to use the requirements in the next point.

Server-facet and Commercial enterprise Logic

Use RESTful and JSON for the communication between the microservices.

Authentication and Unmarried Sign-On with OpenId Join and OAuth 2 are a have-to on this platform strategy. Hence, you can combine all the microservices with all distinct implementation technologies.

User Interface

Portal and Portlets are lifeless. Use Revolutionary Net Apps for any feasible apps. If you need to combine many Innovative Web Apps, just use an integration or toolbar similar to what Google did with its merchandise (see the Google+ image above). If you want local Apps, construct them with Hybrid Utility Framework with native UI, not HTML UI. Open Source products to make your life less complicated for building Modern Net Apps and native Apps with native UI in Java are the following: GWT and J2ObjC. Do not forget them for higher productivity and time to market. Today, a platform strategy does not want to be Based totally on each Unmarried implementation in the identical language; still, if you have a small group emphasis on the equal language and Java is the top programming language available. The subsequent photograph on the cease contemporary this newsletter shows implementation technology for a technical platform Based totally on Java.
