This one is even more weird: it worked on Windows but failed on Linux, using default tools JDK1.6.0_20 on both. The exception thrown was:

The problem was , DateUtil.java had two getDate methods, one taking long parameter, the other taking a String parameter. And Java's XSLT get confused about which one to use:

Following are some bugs in the Xalan jar shipped with JBoss 5.1.0 GA and JBoss 6.0. The Xalan jar file is located in jboss-5.1.0.GA/lib/endorsed ( %JBOSS_HOME%/common/lib for JBoss 6.0).

Apparently, the output is wrong. The string "A test event" should not have been displayed.

XSLT by default writes namespace declarations in the output. Most of the time it's spurious, sometimes outright wrong.
Take this XML:
<?xml version="1.0" encoding="ISO-8859-1"?>

The output is (with JDK1.6):
Title: <br xmlns:java="http://xml.apache.org/x...
The namespace declaration went to the <br> element, not the timestamp where it belongs.
To remove the namespace info, add exclude-result-prefixes to the XSL:

Troubleshooting wifi connectivity is always a headache. I just spent 4 days fixing (actually, finding a workaround for) this problem. Everything worked fine when my PC is connected to a monitor. Then I switched display to my LCD TV with HDMI integrated sound and video. Then my wifi stopped working. The signal strength is perfect and I verified my password a million times (I'm using WPA-PSK). When I tried to connect, it simply fails. No error message, not even an error code! I suspected the HDMI integrated sound driver so I switched sound to the native Realtek driver, still no hope. Then I upgraded the wifi driver to the latest, it didn't help. Uninstalled and reinstalled the driver and rebooted, no difference. What was the...
