Hibernate is the object/relational mapping tool that handles mapping of Java classes to relational tables and Java types to SQL data type. It’s a well-known framework in the Enterprise Java eco-system since it’s being actively developed for the last 16 years.

With this article, I’m going to show the ways of using Hibernate inside a sample application – source code available here – and deploy it onto Payara Server. I will be using the latest version of Hibernate, which is 5.2.10.Final at the time of writing.

Since Java EE 6 it's possible to define data sources in a portable way.

This does mean though that the data source is embedded in the application archive. For some use cases, this is exactly what's needed, but for others it may not be ideal.

In this blog, which follows on from the introduction to Cloud Connectors in Payara Micro, we'll guide you through the process of setting up Payara Micro as a Kafka Client, which can produce and consume data from Apache Kafka.

This blog uses NetBeans 11.1. If you're using an older version, you may need to perform slightly different steps to get the same result.

When testing an app to be run on Payara Server, it can be extremely useful to be able to test your app continuously from your IDE. If you're using NetBeans this is made very easy. Follow the steps in this blog to setup NetBeans to use Payara Server for running your web apps.

As a follow up to our 'Getting Started with Payara Micro Demo', we have another introductory video for you, this time demonstrating the Payara Micro API, using NetBeans and Maven.

Payara Micro allows you to run web applications in a self-contained and easy way. Since the release of the Payara Server in May 2016, there is a simple way to generate an "Uber" JAR that bundles the contents of a WAR file and the classes and resources that compose Payara Micro!

Note that this "Uber" Jar is not the best way to run your application in a Docker container as it requires an update of the entire binary for each small code change you make in the application. A better solution is just to start a Payara Micro Instance and point to the application that needs to be installed. More information can be found on our Payara Micro Docker Image documentation.

Payara Micro 162   can now deploy your artifacts stored in Maven repositories simply by providing the GAV coordinates. This should provide another option for continuous delivery scripts!
