London Java Community

The home for those who work with Java and the JVM

What is LJC about?

The LJC is a broad community of technologists and other associates with Java and JVM-related technologies. Although it is based in London, UK – it has some international membership due to its global programmes (such as Adopt a JSR and Adopt OpenJDK). The LJC hosts regular events including casual catch-ups in a cafe, hack days, evening talks, unconferences, workshops, mentoring, demos, a career mentoring by London’s
Java specialists and much more.

The LJC acts as a voice for Java engineers in London UK as well as globally. This includes but is not limited to creating Adoptium, the world’s leading OpenJDK distribution, representing Java developers worldwide on the Java standards body, and contributing towards charitable works.

Upcoming Event

Modern Java Ecosystems: Advancing Connectivity and Cloud Deployment

As always, this event will allow for insightful discussions on the latest in Graph Technology. This time we will hear sessions about the latest JDBC Driver enhancements for Neo4j and strategies for architecting Java applications for the cloud. Don't miss this opportunity to connect with fellow Java enthusiasts and explore cutting-edge developments in Java technology. Agenda 18:00 - 18:30 Welcome/Snacks 18:30 - 19:00 Session 1: Paulo Menon 19:00 - 19:30 Session 2: Conor Watson 19:30 - 19:45 Q&A 19:45 Networking/Drinks Session 1: Architecting Java Applications for Cloud Deployment - Paulo Menon, RedHat In this engaging discussion, we embark on a journey through digital transformation, unraveling the intricacies of migrating your applications to the cloud platform or start it from scratch. We’ll delve into the optimal architecture to harness the full potential of cloud computing, focusing on Java cloud software architecture and cloud-native principles. Along the way we will cover scalability, performance, best practices and make the most of what the cloud has to offer. We explore the different architecture solutions and development cycle on the cloud. About Paulo: Paulo Menon is a distinguished Principal Consultant at Red Hat, specializing in Cloud Application Development/Architecture for major UK and EMEA clients, managing the EMEA AppDev Community of Practice, and organizing EMEA Tech Meetups, bringing over 23 years of IT experience, including 14 years with Red Hat, to ensure client success, while also actively mentoring and contributing to the London Java community in his spare time. Session 2: Benefits of the new JDBC Driver for Neo4j - Conor Watson, Neo4j The JDBC (java database connectivity) spec is an age-old specification many tools and enterprises use to handle their database connections. However, it makes some assumptions about how that database might look, i.e., it has tables, rows, and columns. This presented a problem for Neo4j as it does not traditionally fit into some of these paradigms. This talk will cover the new 6.0 JDBC driver for Neo4j, how we made it and how Neo4j was massaged into a shape that would be useful for customers, adhere to the JDBC spec and be as sympathetic to the developers using it as possible. About Conor: Conor Watson is a software engineer at Neo4j and is formally part of the drivers team, where he worked on maintaining and extending the bolt protocol that the drivers use to communicate with Neo4j. During his time on this team, he assisted in creating the new 6.0 version of the JDBC driver for Neo4j, a ground-up rewrite. Venue: IDEALondon 69 Wilson St, London EC2A 2BB, UK
