BGJUG – Bulgarian Java User Group


The Bulgarian Java Users Group (BGJUG) is the World’s Java community representative in Bulgaria. The Java Users Groups are local organizations all around the world, which unites various groups of specialists, who are strongly interested in the Java-related technologies. Java Users Groups organize regular formal and informal meetings, conferences and seminars, on which they gather their members in order to exchange information related to Java. Usually, BGJUG members organize seminars and discussions monthly. The invitations for the events are published on this site, in the section “Events“. The materials (such as presentations and demos), created by BGJUG members are collected and stored in the BulgarianJUG youtube

A Bit of History

The first oficial meeting of the Bulgarian JUG took place on 26th of September 2007. Group’s chairman/coordinator is Petar Tahchiev. Since 12th of October 2007 BGJUG maintains mailing list, where are considered questions and problems from the Java World, ideas for future seminars and topics related to the Java-community in Buglaria as well. The mailing list is accessible on the following URL: At the same time had been created the BGJUG’s first site, but its maintenance was discontinued after a few months. On 28th of July 2011 was created the current site, which aim is to represent the group in the Internet and to serve as an information board for meetings organisations. The site aggregates the posts from the group’s members’ blogs related somehow to Java. On the 23rd of September 2011 was created a Twitter account of The BGJUG, which main aim is to represent us in Twitter. It will be used also for sharing news, announcements for meetings and seminars, i.e. everything which concerns BGJUG activities. In 2014 a jPrime conference was created as a huge premium conference organized by the Bulgarian Java User Group. You can find more about it on the dedicated website of jPrime A close after that we started making jProfessionals as a more local yearly conference, this conference was held first in 2015 and happens not only in Sofia, but in Plovdiv as well. In 2016 one of our members Nayden Gochev also started making Java Beer events on monthly bases. This still happens and you can check for such events on
