jTracert is now discontinued and no longer supported! Please use jSonde instead. It's a new tool similar to jTracert but much more powerfull, and it's absolutely free!

Find more details at jSonde site: http://www.jsonde.com/

Introduction

jTracert will allow you to generate sequence diagrams directly from your application runtime! This gives you a lot of advantages:

  • Understand the code created by your colleagues/partners in a short time
  • Rapidly generate documentation for your partners or users.
  • Easily investigate what's happening in large Java applications
  • Excellent companion for a common debugger

Quick Start

Executing jTracert agent

jTracert is implemented as a small javaagent, consisting from only one jar with no dependencies. In order to profile your application with jTracert, just add the following option to VM options: -javaagent:jTracert.jar=7007

IMPORTANT! You should specify a path to jTracert.jar, so your parameter will look like: -javaagent:/home/dmitrybedrin/java/jTracert.jar=7007

7007 here is the port number for communicating with jTracert GUI - you can replace it with any other port.

Please note, that you're not limited to J2SE applications. Add this parameter to your J2EE App server options, and profile your J2EE application. It's also possible to profile applets, and almost all other types of java applications. This is a benefit of implementing jTracert in pure Java.

Executing jTracert GUI

When executing your java application with jTracert agent, you will see the following message:

jTracert agent started Waiting for a connection from jTracert GUI on port 7007

Now start jTracert GUI by executing appropriate shell wrapper (jtracert.cmd on Windows, jtracert.sh on GNU/Linux) or just type java -jar jTracert-gui.jar, and fill in a few fields in connection dialog:

  1. Working folder (in which diagram files will be stored)
  2. Host & port of jTracert agent
  3. A regular expression for filtering classes to be instrumented and analyzed

Click on "Connect" button. That's it!
