For the 9th time, HUJAK (Croatian Java User Association) and HrOUG (Croatian Oracle User Group), are organizing the largest 2.5-days international Java conference in this part of Europe. Our intent is to gather more than 50 interesting sessions from international and domestic speakers, as well as some world-known speakers from this field. We expect more than 300 participants to join us for another great JavaCro conference in Rovinj, one of the top tourist destinations in Croatia.

The JavaCro'20 conference is organized on May 10-12 in the Island Hotel Istra resort situated on the St. Andrew Island near Rovinj, Croatia. Modern hotel resort situated on one of the most beautiful islands in Rovinj Archipelago in Istria is nicely incorporated in the natural habitat with many wonderful pebbly and rocky beaches, preserved cultural heritage in the old castle, spectacular wellness center, and miles of landscaped walkways.

Dear attendees, this is a great opportunity to hear various stories, share experiences, and discuss your projects with many software developers, software architects, and project managers, as well as media representatives, potential partners and clients. As a place of intense social networking, it may also be a natural way not only to discuss your projects and trending technologies but also to seek for new future employees, jobs and partnerships.

Call for Speakers is open until March 22. The Program Committee will decide on acceptance and publication of submitted sessions in the conference Program. The preliminary Agenda will be announced in mid-April.

Traditionally, the JavaCro conference program provides enough time to share knowledge and experiences among participants, both during the day as well as the informal evening social activities.
