Tech Events by London Java Community

The London Java Community's twenty-first unconference, hosted by IBM at 20 York Road on the South Bank. An opening keynote, then an agenda the room builds itself: attendees propose, run and evaluate the breakout sessions, across the JVM, language features and platform engineering. 09:00 to 17:00, GBP 35, with breakfast, lunch and afternoon tea included. Organised by RecWorks on behalf of the LJC, with Hazelcast, Redis, Capital One, Payara and RecWorks sponsoring. The keynote speaker is not named on the listing. The absence of a speaker-audience divide is the format, not an omission: if you want a session on something, you run it. Why go: twenty-one editions in, this is the most durable Java gathering in the city, and the unconference format means the day covers what people are actually fighting with rather than what a programme committee picked months ago. Best for Java and JVM engineers and platform teams.

Please register on eventbrite, who will open the evening with a short talk about the JCP and the wider Java Community — providing inspiration and context for our roundtable discussions. Heather will also explore some of the key JCP working groups and areas of community collaboration, including: Java in Education – supporting the next generation of Java developers and exploring how Java can continue to play a role in education.

The London Java Community meets at Starling Bank's Engine offices in Bishopsgate. One of the oldest and most consistently technical developer groups in the city, and free.

Search has come a long way. From exact matching and Boolean queries to semantic search, embeddings, RAG and agentic AI. Join the London Java Community and Redis for a practical journey through the evolution of search and retrieval, led by Sam Agbede. In this session, Sam will explore how each generation of search has tackled a different challenge, from traditional information retrieval through to the AI-powered systems we're building today.
