Martijn (On behalf of the LJC JCP Committee)

The LJC actually had its 4th birthday on Tuesday and in just 4 years we have established one of the most active and rapidly growing Java User Groups in the world. When opening last weekend’s Open Conference I discussed some of the things we had achieved over the last year within the LJC.

– We now have over 2000 members including 600 that have joined over the last year.

– Over the last year we have had 40 events promoted through the LJC, including 25 of our own events. We have also been able to use the great reach of the LJC to help other user groups and communities such as JBUG and GGUG reach members that may otherwise not have been aware of events.

– We have had over 20 competitions through the group including software licenses, books and free conference passes to 6 different conferences.

Most importantly over the last year we have expanded our community into many new and exciting directions.

– We have given over 20 of our members their first chance at public speaking as part of the new pre-event lightning talks.

– Thanks to Brendan Quinn, we launched the LJC Aggrity site as a way to enable people to follow the personal blogs of all the different LJC organisers and members.

– Thanks to Ged Byrne we have launched the LJC Book club, which is starting to pick up momentum

– Ged and Dave Snowdon have started the regular code share events at Queen Mary University, enabling graduates and senior developers to come together in new ways.

Arguably our greatest milestone was to become part of the JCP and win an open seat on the Java SE/EE executive committee. This has really put us on the map globally and thanks to some great work from the LJC, the JCP committee has launched the ‘adopt a JSR’ program, which has been engaging other Java user groups around the world.

It has been a super year for our community and we should all be very proud. None of this would be possible without an active group of organisers behind the LJC. Thanks to everyone that has got involved over the last year, we have even bigger plans over the coming year and look forward to sharing our journey with you.

What is the LJC

The London Java Community (LJC) is a group of Java Enthusiasts who are interested in benefiting from shared knowledge in the industry. Through our forum and regular meetings you can keep in touch with the latest industry developments, learn new Java (& other JVM) technologies, meet other developers, discuss technical/non technical issues and network further throughout the Java Community.
