What we’re about
The Garden State Java User Group, Inc. (formerly the ACGNJ Java Users Group), in continuous operation since February 2001, is a 501(c)(3) non-profit organization that provides a forum to promote the use of Java platforms, APIs, and language. We strive to facilitate interactive discussions and exchange of ideas relating to the application of Java.
Topics will primarily focus on JVM technologies such as Java EE, Jakarta EE, MicroProfile, Spring, Groovy and Kotlin. Topics on non-JVM technologies such as Meteor, AngularJS, and Rust may occasionally be presented.
We are proud members of the MicroProfile Working Group and the Jakarta EE Ambassadors and have adopted the Jakarta NoSQL specification.
All meetings are generally held on the second Tuesday of the month, but may change due to speaker availability. In-person meetings are usually held at Drew University in Madison, New Jersey. On-line meetings are held via our YouTube channel.

We are pleased to announce that Vladimir Shipovalov and Alok Tribrewala will be presenting their own topics at this month's meeting.
Apache Spark and Databricks in Action: Driving Cost Transparency Platform Through Intelligent Data Processing (presented by Vladimir Shipovalov)
This talk focuses on implementing Apache Spark and Databricks within the Cost Transparency (CT) Platform for intelligent data processing. The CT Platform processes diverse expense data, employing Spark for essential tasks like filtering, merging, enriching, and aggregating information.
A key feature is the Rule Service, a microservice enabling flexible business logic and dynamic rule updates without code changes. The DraftRun Service allows for testing new rules on data subsets. Apache Spark is an open-source distributed engine for various workloads, known for its speed through in-memory computing. Databricks enhances Spark as a cloud platform, offering streamlined cluster management, an optimized runtime, and collaborative tools.
The presentation demonstrates how Spark and Databricks drive efficient data processing in the CT Platform, including practical examples.
Enhancing Java Applications with LangChain4j: Practical AI Integrations (presented by Alok Tribrewala)
This talk explores practical strategies and insights for integrating LangChain4j and Large Language Models (LLMs) within Java applications. Attendees will learn how Java developers can leverage LangChain4j for tasks such as:
- Interpreting Complex Swarm Intelligence: Enhance transparency and interpretability of autonomous drone behaviors by translating complex swarm decisions into clear, actionable insights.
- Automating High-Quality Code Documentation: Improve developer productivity by automating accurate, consistent code documentation and facilitating efficient onboarding.
- Enterprise Integration of LLMs: Simplify and streamline the integration of advanced LLM capabilities in enterprise-grade Java systems.
Attendees will gain actionable knowledge to immediately implement AI-driven solutions using Java and LangChain4j.
