What is a “Balkan spy” doing in Rovinj? When talking about JavaCro – it all makes sense

The JavaCro conference, organised by the Croatian Oracle Users Society and the Croatian Java Users Society, was held in Rovinj from 10 to 12 October.

The company KING ICT supported the conference as its gold sponsor, and KING’s leading software development programmers, Tomislav Petričević and Ivan Andrić, held lectures intended primarily for development engineers and software architects.


Ivan and Tomislav held a lecture about the system of cameras that monitor Croatian roads, which they in jest call the Balkan Spy.

They explained to the participants that by using Java and Spring, they were able to resolve the demanding processing of data from the traffic cameras. In the first part, they discussed the asynchronous detection and processing of traffic violations using the Spring Integration framework.

In the second part, they discussed the real-time detection of vehicles on Croatian roads based on licence plates, and verification of the vehicles in the national and foreign records. They gave an overview of the technical implementation and the abundance of statistical data associated with the quantity of processed inquiries, and system performance.

This was the ninth edition of the conference that brings together those who work with the Java programming language. This year, the conference was attended by more than 250 people. Since programming languages are the languages of the future, it comes as no surprise that there are more and more fans of Java each year.
