Still looking for a Java profiler?

This post is just a short overview on the topic.

Recently I've had to investigate a performance issue of a Java application running under JBoss server. This problem resulted in using a full-featured free Java profiling tool - VisualVM that is available separately and as an embedded JDK tool starting from JDK 6 update 7. Thus, it's most likely already installed on your system. This solution was great in localizing the performance bottleneck on the Production environment in my case. The list of features include monitoring CPU and memory usage, application threads, profiling, sampling, taking thread and heap dumps, etc. I advise to watch the video tutorial on the Getting Started page. Here is my screenshot:
I'm not going to make a thorough comparison of different Java profiler tools here but this is a list of alternatives for completeness:
  • YourKit is free for open-source projects;
  • JProfiler is free for open-source projects;
  • NetBeans profiler is embedded into corresponding IDE and is completely free;
  • Also you should not forget about the embedded JVM features (e.g. threaddumps, java agents, bytecode manipulation) that can be extremely useful especially when you cannot apply a third-party profiler (e.g. critical high-loaded Production systems). Here is a Russian article on this topic that I've translated to English here.

  1. hi, my name is Eugene Shifer, and i'm one of the partners @ DiscoveredByte ( www.discoveredbyte.com ). It looks like, it's been more than a year since your publication, but i still decided to get in touch, in case you are still covering Java development and Java-related tools. Recently, we create Online Java Performance Analysis Tool that resembles some of the features described in your article. however, i think, we created something that gives more granular results while being extremely light on the server resources. i would be very interested to find out how we measure up against competition. we are in Beta, so use of the full-featured version of the software is free. let me know, what you think.

    thank you in advance,
    Eugene

DynamicReports and Spring MVC integration

This is a tutorial on how to exploit DynamicReports reporting library in an existing Spring MVC based web application. It's a continuation to the previous post where DynamicReports has been chosen as the most appropriate solution to implement an export feature in a web application (for my specific use case). The complete code won't be provided here but only the essential code snippets together with usage remarks. Also I've widely used this tutorial that describes a similar problem for an alternative reporting library.
So let's turn to the implementation description and start with a short plan of this how-to:
Adding project dependencies.Implementing the Controller part of the MVC pattern.Modifying the View part of the MVC pattern.Modifying web.xml.Adding project dependencies
I used to apply Maven Project Builder throughout my Java applications, thus the dependencies will be provided in the Maven format.

Maven project pom.xml file:

Do It Yourself Java Profiling

This article is a free translation of the Russian one that is a transcript of the Russian video lecture done by Roman Elizarov at the Application Developer Days 2011 conference.
The lecturer talked about profiling of Java applications without any standalone tools. Instead, it's suggested to use internal JVM features (i.e. threaddumps, java agents, bytecode manipulation) to implement profiling quickly and efficiently. Moreover, it can be applied on Production environments with minimal overhead. This concept is called DIY or "Do It Yourself". Below the lecture's text and slides begin.
Today I'm giving a lecture "Do It Yourself Java Profiling". It's based on the real life experience that was gained during more than 10 years of developing high-loaded finance applications that work with huge amounts of data, millions currency rate changes per second and thousands of online users. As a result, we have to deal with profiling. Application profiling is an i…

Java 8 Lambdas applied to QuickSort algorithm

In this article I'm going to review Java 8 Lambdas use cases after I've watched the Lambdas have come to Java! screencast from Typesafe. As a nice example, I've decided to count comparisons in the Quicksort algorithm. Basic algorithm.Inline lambdas.Method references.Basic algorithm
Here is a basic implementation where we count comparisons in the Quicksort algorithm: public class QuickSort { public static long countComparisons(List<Integer> a) { if (a.size() <= 1) return 0; int p = getPivot(a); int i = 1; for (int j = 1; j < a.size(); j++) { if (a.get(j) < p) { if (j > i) swapInList(a, i, j); i++; } } swapInList(a, 0, i - 1); return countComparisons(a.subList(0, i - 1)) + countComparisons(a.subList(i, a.size())) + a.size() - 1; } private static Integer getPivot(List<Integer> a) { return a.get(0); …
