EJB Support in Piranha via CDI

Since there’s so much existing code using Enterprise Beans (EJB), a certain level of support is still desired. Piranha Cloud takes a somewhat novel approach to Enterprise Beans and maps Enterprise Beans annotations to equivalent functionality in CDI or other Jakarta EE APIs.

The Future of EJB

EJB, or Enterprise Beans, are Java classes with a number of container provided services attached to them, such as transactions, remoting and security. A possible future direction for EJB is to rebase it on CDI. Instead of having those two essentially competing component models in Jakarta EE, we would end up with just one.

Getting Started with Jakarta EE 9: Jakarta EE 9.1

The objective of Jakarta EE 9.1 is to provide certification on Java SE 11 and not to deliver new features.

Do Java/Jakarta EE Standards Matter?

In this myth-busting webinar, Steve Millidge, founder of Payara, will show you why standards like Java EE (i.e., now Jakarta EE) are beneficial. 

If you’ve been thinking standards like Jakarta EE don’t matter, this video will show you how having standards gives you the opportunity to develop future proof applications, among other benefits.

Is the Java/Jakarta EE Deployment Model Out of Date?

In this myth-busting webinar, Steve Millidge, founder of Payara, will show you why the Java EE/Jakarta EE deployment model is not old fashioned or out of date. 

If you think you have to switch to Spring for a modern deployment model, this video will show you how the Jakarta EE deployment model using thin WARs allows you to modernize your application development, today!

Is Java/Jakarta EE Cloud-Native?

If you’ve been hearing that Java/Jakarta EE is not Cloud-native or it’s difficult to get your Java/Jakarta EE applications running in the Cloud, watch this webinar to see why that’s not true and how you can continue using your existing Java/Jakarta EE development skills to modernize your application development!

Are Java/Jakarta EE Application Servers Heavy?

In this myth-busting webinar, Steve Millidge (founder of Payara), demonstrates that Java/Jakarta EE application servers are not resource-heavy or slow. 

Watch live demonstrations of application servers that show it’s possible to have a small footprint and low resource usage in Jakarta EE runtimes.

Introduction to New AutoScale Feature Available in Payara Server

When AutoScale is fully developed, not only will it allow you to change the number of instances in the Deployment Group by implementing additional asadmin commands, but it will also signal the routing systems of the changed configuration and automatically trigger a change in size based on rules around resource usage.

In this first step of the AutoScale development, we have introduced the concept of the Scaling Group into Payara Server Community Edition 5.2021.4 which can alter the number of instances in a Deployment group and implement it for SSH nodes.

The AutoScale feature is in continuous development, with improvements and additional functionality (including addressing the routing issue) planned in our future releases.

Getting Started with Jakarta EE 9: Context And Dependency Injection (CDI)

In this article of the Getting Started with Jakarta EE series, we look at various specifications and how you can use them in your next application.

We explain a few features of Context and Dependency Injection (CDI). The CDI specification is an important backbone of Jakarta EE as it brings several specifications together. Over the years, it became more and more important as an increasing number of specifications started using CDI as the basis for it.

In this article, we will also tell you a bit about the different scopes, the interceptor mechanism, and the Event system.

Why Java Developers Continue to Rely on Jakarta EE

Over the past year, the Eclipse Foundation spoke to leading Java developers around the world to discuss why they rely on Jakarta EE and the unique benefits of using Jakarta EE technologies.

Their input is captured in our white paper, which describes the important advantages Jakarta EE offers today and for the future.

2021 Jakarta EE Developer Survey

This is the fourth Jakarta EE Developer Survey, so it is safe to say that it has become an annual tradition and is your chance to influence the direction of the Jakarta EE working group.

The survey last year had more than 2000 responses from individuals around the World. Let’s beat that number this year!

Getting Started with Jakarta EE 9: How to Create a REST API with Jakarta EE 9

In this second article of the Getting Started with Jakarta EE 9 series, we show you some basic scenarios using the REST specification.

Although most people are using the term REST or RESTful API just to indicate they do data transfer over HTTP, and  ignore the “Hypermedia as the engine of application State (HATEOS)” part of REST. The technology is used a lot lately to connect the front-end with the back-end.

For those who are not familiar with Jakarta EE, this article should give you an indication how to create such a REST API with Jakarta EE 9.
