Tools for MVC in Java EE 8

clip_image002Last week at Devoxx, Manfred Riem (MVC 1.0 Co-Specification Lead) did a session on MVC 1.0 (JSR 371) to a packed room. During the session, Geertjan Wielenga (Principal Product Manager in the Oracle Developer Tools) did a cameo appearance to discuss the tooling in the context of MVC. Amongst other things, Geertjan is looking at some of the potential features an IDE could bring to simplify the development of MVC based applications.  During the session, Geertjan did a demo based on a prototype he wrote for NetBeans. This demo was also using Manfred’s experimental action based prototype.

So clearly, it's early days! After all the MVC Experts Group has just started and is now discussing important orientations for the specification (e.g Should the Controller be based on the Servlet API or should it be layered on top of JAX-RS?). Nevertheless, it is interesting to follow Geertjan's explorations around tooling in that space.  This also demonstrates that adding new features to NetBeans is not necessarily a daunting task!

You can find more details on Geertjan's blog: Tools for MVC in Java EE 8 - Part 1 and Part 2.

Building a Smart Home Server by Using the Java EE 7 WebSocket API

clip_image002

This tutorial shows you how to create an application that uses the WebSocket API for real-time communication between a client and a server. You learn how to:

  • Create a Java Platform, Enterprise Edition 7 (Java EE 7) application that uses the WebSocket API
  • Use the OnOpen and OnMessage WebSocket lifecycle events to perform different actions on the Java EE 7 application.
  • Define a client-side WebSocket endpoint by using JavaScript
  • Operate on Plain Old Java Objects (POJOs), in real-time, with actions invoked from a web browser client

Create RESTful Services and deploy to Oracle Java Cloud Service with Netbeans by Andreas Koop

clip_image002In preparation to one of my DOAG 2014 talks „Java WebApps and Services in Oracle Cloud" I created a new trial account for Oracle Java Cloud Service (http://cloud.oracle.com) two weeks ago. Now was the time to create a RESTful Service and deploy it to the cloud and make it accessible to public. 

Last time I tried the Oracle Cloud I used exclusively JDeveloper, this time I made my experience with Netbeans. From my point of view Netbeans has pretty good support for generating RESTService from Database tables. In a couple of minutes it is possible to create CRUD Operations and make it accesible by a REST endpoint. No matter what content type you prefer, by using JAXB XML and JSON content types are both automatically available.

Prerequites

Step 1: Create an Oracle Java Cloud Service trial account (fee less for 30 days)

Step 2: Download and install Netbeans Version 8.01 (http://www.netbeans.org)

Step 3: Make sure to install the Oracle Cloud plugin (1.5)  in Netbeans

Step 4: Download and Install (just unpack) Oracle Java Cloud  Service - Saas Extension SDK (release 14.1.12.0 Find it here.

Step 5: Next add your Oracle Cloud account as Cloud Provider to Netbeans (Goto „Services" Tab and provide your cloud account details)

Step 6: Add a WebLogic Service Instance under ‚Services Tab', so you are able to test the RESTService locally prior to deploying to Oracle Cloud. (I am not going into detail in this post for that task)

Step 7: Make sure to deploy your DB Schema objects plus data into Oracle Database Cloud Service (when subscribing to Java Cloud Service you will get the DB Service as well). See in my previous posts for more details.

HowTo develop RESTService with Netbeans

Everything is setup for cloud deployment. Now let's create a simple REST-Service on top of the HR  DB Tables EMPLOYEES and DEPARTMENTS.

Step 1: Start Netbeans, Create new Project Wizard from Type „Maven / Web Application"

Step 2: Enter your desired groupId, ArtefactId etc. Read the complete article here and get the presentation here.

Using Java API for WebSockets in JDeveloper 12.1.3 by Eugene Fedorenko

clip_image002Introduction

The latest release of JDeveloper 12c (12.1.3.0) along with WebLogic Server 12.1.3 came up with some new Java EE 7 features. One of them is support of JSR 356 Java API for WebSockets. Actually the WebSocket Protocol (RFC 6455) has been supported starting from 12.1.2.0 release, but it was based on WebLogic specific implementation of the WebSocket API. Now this proprietary WebLogic Server WebSocket API has been deprecated. However, it is still supported for backward compatibility.
In this post I am going to show an example of using JSR 356 Java API for WebSockets in a simple ADF application. The use case is about some sailing regatta which takes place in the Tasman Sea. There are three boats participating in the regatta and they are going to cross the Tasman Sea sailing from Australia to New Zealand coast. The goal of the sample application is to monitor the regatta and inform users about how it is going on, showing the positions of the boats on a map.
We're going to declare a WebSocket server endpoint in the application and when a user opens a page a Java script function opens a new WebSocket connection. The application uses a scheduled service which every second updates boats coordinates and sends a message containing new boats positions to all active WebSocket clients. On the client side a Java script function receives the message and adds markers to the Google map according to the GPS coordinates. So, each user, interested in the regatta, is going to see the same updated picture representing the current status of the competition.

WebSocket server endpoint

Let's start with declaring a WebSocket server endpoint. There is a small issue in the current implementation, which probably will be resolved in future releases. The WebSocket endpoints can not be mixed with ADF pages and they should be deployed in a separate WAR file. The easiest way to do that is to create a separate WebSocket project within the application and to declare all necessary endpoints in this project:

This is also important to set up a readable Java EE Web Context Root for the project: Read the complete article here.

Java SE 8 (and Java EE 7) Comes to WebLogic! By Reza Rahman

As many of you know one of the key features of GlassFish 4.1 was support for Java SE 8. You may be glad to hear that WebLogic 12.1.3 now is also officially certified against Java SE 8. This makes WebLogic one of the earliest major commercially supported Java EE platforms to certify for Java SE 8. Keep in mind, WebLogic 12.1.3 also supports some key Java EE 7 APIs such as WebSocket, JSON-P, JAX-RS 2 and JPA 2.1 (read this excellent Aquarium entry by my colleague Bruno Borges for details).

clip_image001This means that you can start using some of the very well received Java SE 8 features such as lambdas, streams and the new Date-Time API in Java EE 6 and Java EE 7 applications even in the most demanding 24 x 7 enterprise environments. WebLogic 12.1.3 has also taken advantage of new JDK 8 features such as improved garbage collection, security enhancements and JDBC 4.2.

You can read more details in a well written blog entry by Steve Felts of the WebLogic team.

Showcase your custom Java Applications on the Oracle Cloud

As you’re probably already aware Oracle is already a major player in the Public Cloud space, and our business is growing rapidly.

We are already the world’s second biggest SaaS (Software as a Service) provider, with the number one spot firmly in our sights. Our PaaS (Platform as a Service) and IaaS (Infrastructure as a Service) are also growing rapidly.

The key thing about Oracle is that we will offer all the layers of the cloud rather than just focussing on one tier. One way to get a feel for the breadth of offer is to check out cloud.oracle.com. Many of these services are already in or soon will be available for trial, and you can expect some exciting announcements at Oracle Open World.

This means that your customers will have the option of deploying part or all of their systems onto the Oracle Cloud.

The Oracle Cloud is a great platform for deploying custom Java applications that you have developed with or for your customers. The Oracle Java Cloud Service has been extended, and now offers dedicated virtual machines for your WebLogic Server cluster. These have Weblogic 11g or 12c installed and management tooling.

So if you have Java EE or ADF applications that you would like to try or showcase on the Oracle Cloud, please let us know (email Pascal Giraud), and you can demonstrate to your customers that you are a leader with this new platform.
