Open Source Debugging Tools

Open Source is not just a suite of libraries you consume within your application, but now reaches into the space of tools to help you troubleshoot and improve your applications.

This session will quickly survey a wide range of tools across the Java, Networking, Filesystem, SOAP, REST, HTML, CSS and JavaScript realms. We'll look at applications such as VisualVM, which help you analyze your heap and garbage collection cycles of both local and remote applications. Performance and load testing tools such as JMeter will expose bottlenecks, threading, and scalability concerns of everything from Java modules to Web Apps (even ones that don't use any Java).

Learn how web service tools such as SOAPui and TCPMon allow you to inspect your SOAP and REST calls at the data structure level, and how Firefox Poster lets you test web services right from the browser. And when only a raw look will do, we can always fall back on the venerable TCPDump.

This tool-centric presentation will expose developers to approaches to inspect, debug, tune and troubleshoot Java desktop apps, language-neutral web apps, and framework-neutral web services using Open Source Tools.
