My problem is simple: in my XML data, a timestamp is provided as a long integer (number of milliseconds since the "the epoch"). When I do XSLT, I want to display it as a readable string, such as "Mon Nov 01 18:08:48 CDT 2010". After hours of struggle, I found: It's not so easy to get the job done with JDK 1.6 There are tons of garbage on the web in this space (suggestions, code snippets that simply don't work) Simple Xalan extension functions was the only resource that's somewhat informative. Even there some of the examples don't work. Below is a list of what worked and what didn't. This works:
<xsl:stylesheet version="1.0" xmlns:xsl="h... This does not (providing long value to Date constructor): <xsl:stylesheet version="1.0" xmlns:xsl="h......

Use javax.xml.parsers.DocumentBuilder to parse xml. DocumentBuilder.parse() takes:
java.io.File
org.xml.sax.InputSource
java.io.InputStream
java.lang.String as a URI to an XML document
Example code:
import java.io.*;
import javax.xml.parsers.Docu...

Inventory list for configuring a JDBC data source in JBoss:
Put *-ds.xml configuration file in server/yourServer/deploy , e.g., hsqldb-ds.xml

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...
