Enterprise Java

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

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.

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.

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.

Edson Yanaga explains what’s new in the updated Effective Java and shares more tips not included in the book.

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.

Speed up Maven builds in Tekton Pipelines

Speed up Maven builds in Tekton Pipelines

February 26, 2020

Tekton is an open source project that provides standard Kubernetes-style resources and building blocks for creating CI/CD pipelines that can run on any Kubernetes. Tekton does this by introducing a number of custom resource definitions (CRD) such as Pipeline, Task, and ClusterTask to provide a language and structure for defining delivery pipelines as shown in […]

Designing an event-driven business process at scale: A health management example, Part 1

February 19, 2020

The concept of a business process (BP), or workflow (WF), and the discipline and practice of business process management (BPM) have been around since the early 90s. Since then, WF/BPM tools have evolved considerably. More recently, a convergence of different tools has taken place, adding decision management (DM) and case management (CM) to the mix. […]

Camel K standalone Java file: Now with Java language support

February 3, 2020

Apache Camel K should be as lightweight as possible. Therefore, the Camel K project provides standalone Java files to describe a Camel integration. The downside to this practice is that existing IDEs cannot provide complete support out of the box. To provide a complete experience with Apache Camel K’s standalone Java files, there were three […]
