JakartaEE

The amount of data collected by applications nowadays is growing rapidly. Many of them need to support both relational SQL and non-relational NoSQL databases. Jakarta Data provides an API to allow easy data access. Developers can split the persistence mechanism and the model using common features like the Repository pattern and seamlessly switch between SQL and NoSQL databases or even use both in the same application.

Open Source Best Practices

Eclipse ❤️ Java

Hendrik Ebbers (Open Elements GmbH)

Years ago, most developers would simply download Java from Sun or Oracle and deploy a monolithic application on an enterprise application server. However, things have changed, and developers now have the option to choose between multiple OpenJDK distributions and create applications or microservices using frameworks such as Spring Boot, Micronaut, or Quarkus. While all these products and tools contribute to a more diverse ecosystem, underlying standards and specifications are still shared.

Modernizing Jakarta RESTful APIs to run serverless

Dennis Kieselhorst (Amazon Web Services EMEA SARL)

Maximilian Schellhorn (AWS)

Jakarta EE provides a comprehensive set of vendor neutral, open specifications that can be used for developing modern, cloud native Java applications from the ground up. However there are also a lot of existing applications build on top of it’s predecessors J2EE and Java EE before the specifications moved to the Eclipse Foundation.

In this session we discuss modernization pathways that make traditional Java enterprise applications more Cloud Native while preserving the existing investments. As a concrete example we’ll take a backend application running on a classic application server that provides RESTful services using Eclipse Jersey. We’ll be replatforming it to run as a serverless function on AWS Lambda with minimal code changes.

Enterprise Kotlin: Jakarta EE for Kotlin developers

Mads Opheim (Work for Computas)

Kotlin is gaining traction and widespread usage, while Jakarta EE is developing faster than ever. What happens if we mix them together?

In this talk, we’ll create a simple application, utilizing many of the Jakarta EE specifications, including Restful web services, JSON Binding, persistence, Bean Validation and more. We’ll do it in Kotlin, and show you the pitfalls you might run into as well as how to get around them.

By the end of the talk, we’ll have passed all the pitfalls, and we'll have a running application, with Kotlin powered by Jakarta EE.

Revolutionize Your Data Persistence: Streamline Your Life with Data and NoSQL Integration

Otavio Santana (Self-employed)

After more than 15 years of JPA existence, the rise of NoSQL storages, and the increasing popularity of microservices architecture, software engineers have faced new challenges when defining reliable persistence layers. The persistence layer has on its shoulders the heaviest weight of responsibility when considering architectures that are - or should we say, should be - customer-centric and domain-driven, resilient and scalable, and finally, evolutionary.
