On June 5, Kharkiv wish host the second ThinkJava # 2 developer conference . Hither you can get familiar with with new technologies and methodologies, pick up more about the possibilities of the Java and NoSQL world, well-nig debugging Java applications victimisation JDK tools and connecting to JVMs on the fly, and much more.

This time, two Java duets act as speakers:

Debugging a Java application with air manpower
R.C. Vasilenko and Alexander Bondarets

As a dominate, Java developers debug with intelligent-made tools from the IDE, or use of goods and services popular libraries and utilities (YourKit, jProfiler, JavaMelody). But a few people know that most of the problems can be solved using the tools available in the JDK. Furthermore, with these tools you can more in effect and conveniently create a solution adapted to your project. We will verbalise about performance counters (jvmstat Performance Counters), which bear all the essential information about the State Department of the JVM, the mechanism for connecting to the JVM happening the fly (Dynamic Tie), equally well as the individual capabilities of the Instrumentation API and java agents. What if the problem can lone atomic number 4 detected along product and the application program cannot be stopped? How to fix a bug without fillet the application? All this bequeath be discussed in the report.

No Mongo, No Honey and NoSQL
Dmitry Zyukin and Egor Bondar

Technologies are development past leaps and bounds. It is still possible for a prospicient fourth dimension to possess in question knowledge without replenishing them. However, often established technologies are replaced by others at an amazing rate.

In the Java Enterprise world, you rarely have to change something and change yourself. Everyone is used to extant in a worldly concern of relational databases, where everything is determinate and clear. However, life does not support still, and customers increasingly come up with requirements that characteristic nonclassical terms, including NoSQL Datasource. Or the start project contains in the requirements such volumes of data that it is very difficult to put into the matrix of relational databases.

What if you met a NoSQL wizardly spell? In the report, we will consider the features of working with the document-oriented NoSQL database - MongoDB, which is well-known to everyone. As Coffee developers, we need to exist fit to rebuild our "relational mode". Firstly, you need to understand the basic concepts that wish help you quickly understand what is at stake when in MongoDB you want to run into a table, and you pay off a document. After that, you can go connected to queries and building a data model. But here we will not be larboard alone: ​​omnipotent libraries and frameworks will resuscitate our aid. The report will also demonstrate the use of MongoDB in a real application, where the GMongo library is used on the Java side. So there will atomic number 4 a trifle of MongoDB, Java and Groovy :).

To take part in ThinkJava # 2 you require to cash register in our groupMeetup . Participation is free!

The conference will be held connected June 5 in Kharkov, in the conference hall of Metallist IC. Beginning at 19.00. Enrollment of guests opens at 18.45.
