Preface

Introduction

The JBoss ecosystem is very large and dynamic; the JBoss community drives innovation every day to bring the best projects and products to the world. This book does not pretend to cover all possible and imaginable JBoss products in detail, but this book aims to be the best and fastest getting-started guide for Enterprise application development with the JBoss brand.

The book covers five main parts:

Part 1 explores the basics, Users will be presented the global project we will cover progressively during this book, JBoss developer studio.

This part also presents the BeOS Bank project example that will drive the chapters and labs.

Chapter 1, Introduction to the JBoss Ecosystem, presents the users with the project, that will serve as a guide throughout this book. The chapter also introduces JBoss developer studio's features in order to improve developer productivity.

Part 2 covers web application development and deployment with the JBoss EAP and Undertow.

Chapter 2, Developing and Hosting Scalable Web Applications, takes a look at developing and hosting scalable web applications using JBoss Application Server. The user will learn how to develop and deploy scalable web applications and monitor their states on JBoss Application Server. Users will also get hands-on JBoss EAP configuration tips to tune the platform to respond to various operational events.

Chapter 3, Custom Web Deployment Using Undertow and Swarm, explains that Undertow is the default web server included in JBoss Application Server. In the last chapter, users implicitly used the embedded version of Undertow in JBoss AS to host applications; this chapter is about handling custom deployment scenarios by embedding Undertow in Java applications on one hand but also teaching how to package existing Java EE component as microservices using Wildfly Swarm. The user will also learn how to set up highly available deployments and build microservices with Undertow

Part 3 is centered on data management tools in the JBoss ecosystem. It covers data caching with JBoss Data Grid and data refactoring using JBoss data virtualization.

Chapter 4, Storing and Accessing Distributed Data, deals with data caching in a JBoss ecosystem with JBoss Data Grid/Infinispan; various configuration tips will be experimented through labs and coding sessions. The chapter also shows how to store and retrieve data from local and remote caches, how to develop and deploy cache-based applications, how to listen to cache event, and how to leverage the Advanced Cache API.

Chapter 5, Exposing Data as a Service, outlines data virtualization with JBoss Data Virtualization tools through illustrated examples; you will discover how to create aggregated, unified, and virtualized views from disparate data sources, how to create source models and virtual models, how to query join data from various sources, and finally, how to expose data views as a service.

Part 4 is about Enterprise Service Bus (ESB) and messaging. We will discuss JBoss Fuse ESB's features and development guide as the well as JBoss AMQ messaging platform.

Chapter 6, Integrating Applications with JBoss Fuse, is organized around application and component integration. After a brief presentation of the JBoss Fuse architecture, it progressively teaches how to develop, deploy, and monitor various OSGi integration scenarios on JBoss Fuse Platform, and explore some integration patterns with Apache Camel through illustrated cases.

Chapter 7, Delivers Information Safely and Connects IoT, discusses how to weakly couple distributed systems using the JBoss AMQ messaging platform. Through practical business cases, users will learn how to set up broker configuration, and how to build and run applications that rely on JBoss AMQ to share data in a safe and reliable way.

Part 5; at the end of the journey, a company is governed by processes and rules; this part covers both business rule and business process application development with JBoss products.

Chapter 8, Making Better Decisions in Your Applications, introduces artificial intelligence programming using the JBoss ecosystem. JBoss Business Rule Management System (BRMS) and Drools Rule Language (DRL) features are explored to build rule-based applications, decision tables, and complex event handlers.

Chapter 9, Developing Workflows, takes you through how to develop workflow applications using JBoss Business Process Management Suite. Process/activities modeling tasks/event handling are explained through practical use cases. Human interaction through forms is covered to enable users to design and test real-life advanced business processes.

Introduction to the JBoss Ecosystem

JBoss initially referred to an application server edited by JBoss Inc. The first JBoss version was designed by Marc Fleury; he incorporated the JBoss Company in 1999 with an innovative business model around services, training, and certifications.

JBoss is fully written in Java, and it obtained the Java 2 Enterprise Edition version 1.4 certification in 2004. This standardization by SUN Microsystems largely contributed to propel the Jboss application server into large accounts to the point of making it a first choice element while deploying enterprise Java applications.

This situation has naturally fueled the appetite in companies looking for external growth, and it was almost natural that Red Hat Inc. acquired Jboss in 2006 to embrace the service industry.

One decade after, the most important acquisition in history, Red Hat has not only worked to significantly improve the JBoss application server, but has also been designing a strong portfolio of middleware and application development products, which also have the JBoss denomination.

Today, the Red Hat JBoss Middleware portfolio is mainly maintained by the open source community and the Red Hat JBoss division. It covers a set of products to enable developers to have the tools they need to create, integrate, deploy, and manage enterprise applications. Regarding the product delivery strategy, there are two main editions for each product: a community edition driven by the open source Community, and an Enterprise edition taken from the community stream.

The community edition is open source and is available to all for free while the Enterprise edition is accessible through a subscription. With the subscription model, companies, organizations, and individuals with an active subscription are allowed to download and use Red Hat certified and tested enterprise software; the editor, in return, provides them with guidance, support, patches, updates, and services around the product through an online network.

Even if there are two distinct editions, it is truly an open organization; bug fixes, for example, from the community version are reported in the commercial edition and vice versa. Red Hat provides and maintains the tested configuration for each product enterprise version release.

The JBoss ecosystem is very large indeed, from developers tools to application platforms. JBoss products now cover the following categories: applications and web servers, enterprise service buses, messaging, data management platforms, rules, workflow management, services, APIs and many other features.

You may have often wondered what is the best JBoss product to solve a specific problem or need, how to get started with a specific JBoss product, or how to integrate different JBoss products in your IT systems.

Through hands-on labs from the business world, this book presents practical use cases that you can leverage to build your own enterprise services around the JBoss ecosystem. In this chapter, we will cover the following topics:

Presenting the global project that will serve as a compass throughout the book

Installing and setting up the JBoss developer studio

Setting up the integration stack, to start our Jboss development journey

Creating our first project

Creating objects using the Forge console

Beos bank project

Beos bank is a financial institution that operates worldwide, and its main locations are in five continents: Mexico, Boston, Chennai, Paris, and Baham. Beos bank provides various digital financial services, including mobile banking and instant payment. It also allows individuals and companies to realize money transfers and cross-border remittances. As a lead developer, the reader will have the responsibility to drive the Beos bank digital transformation using JBoss products. The following projects have been identified to make Beos bank the next billion-dollar company:

Money transfer web application

:Users have been complaining about the instability of the current web transfer portal--sometimes servers go down during transfer operations and user data is lost. You have to set up a new architecture to deploy the money transfer application to support new business reorganization. Develop a new transfer application allowing users to send money to a recipient using JSF, and use JBoss EAP to host and cluster the application. Configure and test the session replication between 02 or 03 nodes. Deploy a HA cluster behind an undertow load balancer and check load balancing features; persist transfers data using JPA and JBoss data sources.

Banking API Management System

:Use Undertow to build and deploy serverless microservices for staff/user authenticated money transfer requests. Use Undertow to reduce the server park and help Beos bank enter the microservices and container world; this program will also help the bank achieve ISO 50001 certification.

Withdraw remittances

:Beos bank has a centralized database to host transfer data; some countries are complaining about the response time to validate a transaction: poor network connections, timeouts, and so on. Use a JBoss data grid cluster to keep in different countries. Use the JBoss data grid Hot Rod client to validate user remittances

.

Cash and currency management

:Beos bank would like to be agile enough to quickly adapt to new regulation policies and would like the transfer fees and commissions to depend on both the sender and receiver countries. Coding this rule, use the BRMS decision table to compute transfer fees based on country and ranges. Use the Virtual Data Model from Yahoo and partners to convert currency rates, and use JBoss Data Virtualization to refactor the price catalog from different countries.

Fraud detection system

:Some illegal transactions have been identified; use BRMS rules, Complex Event processing, and a real-time decision server to detect frauds and illegal transactions. Use the Virtual Data Model from Yahoo and partners to convert currencies.

Invoices and accounting

: Use the JBoss Fuse OSGi flow to process/send bills, and use JBoss Fuse to send a file to regulatory institutions.

Promotions and coupons

:Use JBoss AMQ to notify the partner working on loyalty cards, and use JBoss AMQ to communicate with a mission critical-bank approval system with no message lost. Configure Active MQ to support various runtime and production incidents.

Customer relationship management

:Users are complaining about some Beos bank processes in some countries. Design the incriminated Beos bank business processes with JBoss BPM and improve the process.

In all the book, we will be relying on System.out.println(String out) to print some output on the console when needed; for more advanced ouputs you can refer to String.format method to format the output before printing it to the console.

To understand all the coding stuff related to this project, we will work with a brilliant project called JBoss Developer Studio.

JBoss Developer Studio

JBoss Developer Studio (JBDS) is a development environment created on top of Eclipse and is currently developed by the Red Hat JBoss division. Some companies such as Exadel, the Eclipse foundation, and open source individuals are also working on the JBoss Developer Studio project. JBDS empowers users with a set of plugins, called JBoss Tools; it supports multiple programming models, frameworks, and technologies, including Maven, SVN, and Git.

JBoss Developer Studio is modular like Eclipse and supports development with multiple JVM versions. At the time of writing this book, the last JBDS release version is 10.3.0. JBDS is available as other Jboss products on the Red Hat developer portal--developers.redhat.com; you need a social account (GitHub, Stack Overflow, Linkedin, Twitter, Facebook, Google, or Microsoft) and credentials to download the software.

Installation

JBoss Developer studio installation requires the following configuration:

4 GB RAM (minimum 2 GB RAM)

2 GB hard disk space

JDK 8 to run, but it can deploy applications using lower versions

Download devstudio-10.3.0.GA-installer-standalone.jar and begin the installation using the following command:

java -jar devstudio-10.3.0.GA-incstaller-standalone.jar

This installation needs JRE 8 to proceed; once launched, the GUI installer starts an installation workflow where you will have to click on the Next button to move to the next step:

The installation wizard has nine steps, which are easy to follow:

Read and accept the terms of the license agreement:

Installation is done by default in /Applications/devstudio; you can change this directory to use a custom one:

Select the default Java 8 Virtual machine and click on Next button:

JBDS can scan specific directories to reference your existing JBoss servers.

We will not add a specific location for now; we will just move on to the next steps:

The installer displays the installation path, the component to be installed, as well as the available and required space on your computer. Click on the Next button to proceed with the installation:

In step 7/9 details of each installed component are printed on screen. Wait for the overall installation process to complete:

Click on Done to finish, with the Run Red Hat JBoss Developer after installation option checked. Select a fresh workspace to reach the welcome view.

We will use the $HOME/jbdevgWorkspace folder for our installation throughout this book:

This completes the JBDS installation. Once the JBDS installation is complete, you need to ensure that all the development plugins are also installed. While working with JBoss, the integration stack provides a set of plugins and features to ease the development process; let's install the JBoss integration stack plugin.

Integration Stack

By default, JBoss Tools is installed along with JBDS; this is not the case for the JBoss Integration Stack, which provides users with a toolset to integrate applications. It works with Apache Camel, JBoss Data virtualization, and various others features related to Integration.

The most simple way to install the JBoss Integration Stack is from the Red Hat central view:

Check the listed options:

JBoss Fuse Development

JBoss Data Virtualization Development

JBoss Business Process and Rule Development

JBoss Integration and SOA Development

Integration stack plugins can also be installed from a ZIP file at http://tools.jboss.org/downloads/devstudio_is/.

Click on the install/update button and complete the installation steps. Each plugin has its own working problem to solve, and the user manual, as far as possible, refers to the official documentation of the plugin. In the current section, we install both the JBoss Developer Studio and the Integration stack plugin. We are now ready to create projects and work on them within the IDE. JBDS has an integrated console, called the Forge console, to perform some tasks quickly. In the next section, we will perform various project tasks using this console.

The Forge console

The Forge console provides an integrated command-line interface in the IDE. The Forge console command actions automatically synchronize the workspace views. Forge brings out a powerful command line interface to interact with the IDE. Forge is also available as an Eclipse wizard for users who really don’t want to remember the commands. We will perform various Forge console tasks on a new Java project called Name bank-forge-demo.

Working with the Forge CLI

In order to interact with the Forge CLI, the console needs to be started. In the quickview, search for Forge console; click on the green button to start the Forge CLI:

The command line starts, and a shell is opened on the current workspace directory. You can now enter various commands to create projects, and to interact with the project model and objects. Now, let's see how to create a project using the Forge console.

Creating Maven projects

Use the command list to see the commands available and the man command to get help on a specific command's usage. Forge commands work both interactively and with options. To create a new project, use the project-new command, and provide answers to the interactive questions asked.
