Free Java Training Videos Now Available: From Fundamentals to Modern Frameworks

Wed, 01 Apr 2026 12:00:01 +0000

A comprehensive collection of Java training videos is now publicly available, offering developers valuable insights into modern backend technologies and frameworks.

The playlists cover key topics including Spring Boot, Quarkus, Helidon, Payara, EclipseStore, and MicroStream, providing both a strong foundation and deeper technical understanding. The content is designed for developers at all levels—from those starting with modern Java frameworks to experienced engineers looking to refine their expertise.

Structured Learning Across the Java Ecosystem

Rather than presenting isolated tutorials, the playlists follow a structured approach that helps developers build a coherent understanding of essential concepts such as dependency injection, microservices architecture, data persistence, and performance optimization.

Bring AI into your Jakarta EE apps with LangChain4J-CDI (formerly SmallRye-LLM)

Wed, 25 Feb 2026 07:00:01 +0000

Goal: This article will demonstrate how to add AI features to a Jakarta EE / MicroProfile application using LangChain4J‑CDI, with simple to implement examples that runs on Payara, WildFly, Open Liberty, Helidon, Quarkus or any CDI 4.x compatible runtime.

What is LangChain4J-CDI?

Langchain4J is a Java library that simplifies the integration of AI and LLMs easier, and with their feature of AI services it provides a declarative and type-safe API for developers to define interfaces that represent AI services, abstracting away the complexities of direct LLM communication

AI Tools for Jakarta EE

Thu, 24 Apr 2025 23:42:38 +0000

Introduction

Artificial Intelligence (AI) is transforming the world of software development, including Jakarta EE. Traditionally, developers relied on project generators, visual designers, and IDE auto-completion to build applications. However, these tools often lacked adaptability, context awareness, and efficiency. AI-powered tools such as Payara Starter and Jeddict AI Assistant are now addressing these limitations, accelerating development workflows, and empowering developers to focus on innovation. This article explores how these tools enhance Jakarta EE development, using a conference application as a practical example. Additionally, it discusses future possibilities, including AI assistants integrated with Payara Server for server setup and diagnostics.
