JDD – those three letters electrify all Java enthusiasts. JDD conference attracts large number of visitors every year. This year’s edition takes place under the slogan “let’s build Java universe together!” – it attracted a record number of 900 participants. This is undoubtedly the most spectacular edition of JDD since the beginning of this project. The success of this year’s edition is also owed to an important contribution of Symentis. Three members of the JDD Program Council are our trainers: Tomek Borek, Kuba Marchwicki and Jarek Pałka. All three of them were also the speakers at this year’s edition. Moreover, Jarek Pałka was listed as one of the best JDD speakers!
