Featured Sessions
langchain4j-cdi: Infuse your Jakarta and MicroProfile applications with all the AI
Generative AI burst on to the public scene in November 2022, over ten years after Andrew Ng’s Machine Learning premiered on Coursera. Java developers have long felt like second class citizens, compared to the cool Python kids. LangChain4J changes the game. Java is cool with AI now! This lecture from 30-year industry veteran Ed Burns explores why it took so long for Java developers to have access to easy-to-use AI libraries, compared to Python developers.
This session introduces the new langchain4j-cdi repository within the LangChain4j GitHub organization. Combine the power of Jakarta EE with the reach of LangChain4j. All the idioms you know and love from Jakarta now work with all the AI exposed by LangChain4j: injection, validation, persistence, REST and more!

To Java 25 and Beyond!
Java 25 is the next version with LTS support, and with it comes many exciting changes. In this presentation we will do a rapid review of some of the key changes to the JDK from 11-21 and how they have improved developer experience, performance, and supporting Java applications in production. We will then transition to what Java looks like in a post JDK 21 environment, and where Java will be heading to in JDK 25 and beyond!
If you want to learn about the current state of Java and were its heading, this is the presentation for you.

Impressions from past IBM TechXchange conferences
Motivation
We love Java. That’s why we want to bring together Java developers from all over the world. To learn, to connect, to have fun. The feedback we receive proves us right and motivates us to keep going.
Team
JCON is a team effort and a conference by developers for developers. The JUG Oberpfalz does the heavy lifting in organizing everything. But the heart of the conference are our speakers with their sessions.
Community
We often work in completely different branches, but Java is our common denominator and connects us all. Over the years, not only acquaintances but friendships have formed on account of JCON!
