Paul Sandoz and I have developed an extension to Japex to support native drivers. This allows a benchmark to compare the relative performance of a C-based XML parser vs. a Java-based XML parser, for example. Every native driver is an instance of the class com.sun.japex.jdsl.JapexNativeDriver which defines a native method corresponding to each phase in Japex. An important requirement for this...
Despite some similarities, performance testing and conformance testing are different types of activities, and certainly not every conformance test is necessarily a good performance test. There have been some attempts to using JUnit for performance testing, notably JUnitPerf. Rather than extending a conformance framework for performance purposes, we took the opposite approach and extended Japex, a...
I use a Powerbook laptop connected to a 20" flat panel as the "display hub" in my office. As much as possible, I'd like to run Windows or Unix applications remotely displaying on the Mac. I've recently got a new Ultra 20 Workstation running Solaris 10 but run into a problem when trying to display certain X11 applications on the Powerbook using Apple's X11 server.

Japex has experienced tremendous growth during the last few months, to the point of deserving its own project at Java.net (up until now it was part of the Fast Infoset project). This is the official announcement for the creation of this new project, so please stop by and join us! There's...
