Unleashing the Potential: Evaluating ChatGPT's Jakarta EE Coding Ability

As the field of natural language processing advances, language models like ChatGPT, powered by the GPT-3.5 architecture, have gained remarkable proficiency in generating human-like text across various domains. With the popularity of Jakarta EE (formerly known as Java EE) for enterprise application development, it is crucial to assess the capabilities of ChatGPT in writing Jakarta EE code and determine if developers can rely on it for their projects.

GraalVM, CRaC, Leyden and friends - in search of TRULY cloud-native Java

Artur Skowroński (VirtusLab)

Although the term "Cloud Native" in the context of Java has been repeated ad nauseam for years, the JVM as a platform has only recently entered a phase where everything truly aligns with how cloud-native architectures are designed. Let's trace the path Java has already taken in recent years and take a look at what lies ahead in the future. During this presentation, you will learn about projects such as Leyden, CRaC, and GraalVM, and how they can realistically influence the way applications are developed.

Jakarta Data - Standardized Data Access for SQL and NoSQL Databases

Werner Keil (Self Employed)

Emily Jiang (IBM)

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.

Designing a DSL That Perfectly Solves Your Problem

Irina Artemeva (TypeFox GmbH)

Why might you want to create your own domain-specific language (DSL)? It's easier to use and more effective for a particular problem since, unlike general-purpose programming languages (GPLs), DSLs are tailored to a specific domain. However, identifying a problem that can be solved by a DSL and designing the DSL can be challenging. DSLs are supposed to be concise yet expressive, feature-complete, but should not re-implement your favourite GPL.
