Enterprise Java

Skip the noise that can come with developing apps, and instead focus on building apps.

Calling all developers!

Using the Free #Developer#Sandbox​ for #RedHat#OpenShift​, we will demo how you can take your existing source code or create a new application, easily deploy and manage them as containers, edit the code from our integrated developer experience, and much more.

What is enterprise Java programming?

Enterprise Java is the use of Java for application development in enterprise-scale software, and merges a collection of APIs and application servers that implement those APIs. Enterprise Java also includes related technologies, such as the Spring Framework.  

Enterprise Java Beans (EJB), Java Message Service (JMS), Java Persistence API (JPA), Java Transaction API (JTA), and Java Server Faces (JSF) make up the collection of modular tools that enable enterprise needs, such as distributed computing utilizing containers, web services, and high performance applications. 

Enterprises use Java today to build applications utilizing microservices rather than taking a monolithic approach. Enterprise Java is used across government, telecom, banking information systems, accounting, and e-commerce.

Deploy a Java application on Kubernetes in minutes

Move your legacy Java application into a container and deploy it to Kubernetes. The free Developer Sandbox for Red Hat OpenShift is a free OpenShift cluster that gives you access to the cutting-edge technologies built on Kubernetes. A quick sign-up gets you a cluster and access to a set of developer tools and services.

Try out the Source-to-Image (s2i) feature in the free Developer Sandbox for Red Hat OpenShift by following along with the Spring Petclinic application learning experience.

 

Microservices for Java Developers book cover

Free book: Microservices for Java Developers

The microservice architectural approach lets you build complex systems to adapt to rapidly changing competitive markets. Now in its second edition, this step-by-step guide introduces concepts such as immutable delivery, and gets you started building distributed systems for managing microservices using Linux containers, Kubernetes, and three different Java frameworks: Spring BootDropwizard, and WildFly Swarm (WildFly Swarm was renamed Thorntail in 2018).

 

Learn how to:

  • Expose a service.
  • Configure at runtime.
  • Expose metrics and insight.
  • Call downstream services in a safe manner.

Building Reactive Microservices in Java

Free book: Building Reactive Microservices in Java

Eclipse Vert.x is a toolkit that helps developers build reactive applications to run within the Java Virtual Machine. Whether you want to get rid of your monolithic enterprise applications, or avoid creating new ones, Eclipse Vert.x is worth investigating. Learn how to use reactive design to create distributed, reactive microservices within this framework. 

 

This book explains how to:

  • Explore the elements of reactive microservices and learn how Vert.x works.
  • Build and consume a single microservice to understand how messaging improves its reactiveness.
  • Create an entire microservices system, using stability and resilience patterns to manage failures.
  • Use the OpenShift container platform to deploy and manage microservices in a virtual or cloud environment.

After giving a quick introduction to Kogito, Maciej Swiderski will explain how it can be used to build cloud-ready, event-driven business applications. This will be followed with a demonstration of how Quarkus (with its hot reload capabilities) can be used to create microservices implementing the business logic of a complex domain with rules and modeling its workflows through business processes integrated with Kafka to consume and produce business events.

In this tutorial, Burr Sutter demonstrates how to optimize your enterprise Java apps, your APIs, your microservices, and your “serverless functions” for a Kubernetes/OpenShift environment—vastly smaller, vastly faster, and fundamentally more scalable.
