Tomcat allows you to create multiple server instances for the same installation. The installation directory is identified as CATALINA_HOME , the instance directory is identified as CATALINA_BASE . Here are the steps: Create a base directory for the new instance, for example: /home/nogeek/tomcat1 . Create the subdirectories:
mkdir -p /home/nogeek/tomcat/{bin,conf,logs,temp,w... Copy web.xml from the installation directory: cp $CATALINA_HOME/conf/web.xml /home/nogeek/tomcat...

There is no XSLT 2.0 support in the JDK as of 7.0. According to Stackoverflow , there are three Java packages that support XSLT 2.0: Saxon IBM WebSphere XML Feature Pack Oracle XDK There are no known support for XSLT in browsers. According to Wikipedia : XSLT is developed by the World Wide Web Consortium (W3C). The most recent version is XSLT 2.0, which reached W3C recommendation status on 23 January 2007. As of 2010, however, XSLT 1.0 is still widely used, as there are no products that support XSLT 2.0 running in the browser, nor on some important server environments such as LAMP. Expressions like this:
format-date(xs:date('1999-12-31'), '[D01] [MNn] ... where format-date is a XSLT 2.0 function and date is a XPath 2.0 constructor...

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......

This is the opposite of parsing. You can use javax.xml.transform.Transformer to output a DOM tree to a file.

You can use the javax.xml.transform.Transformer class to "transform" an XML stream (string in this case) to a DOM tree - effectively parsing the XML string.

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
Other needed files in server/yourServer/deploy : jboss-local-jdbc.rar , jboss-xa-jdbc.rar , jca-jboss-beans.xml , transaction-jboss-beans.xml
Copy jboss-jca.deployer directory to server/yourServer/deployers
Copy standardjbosscmp-jdbc.xml to server/yourServer/conf
Make sure the following lines appear in server/yourServer/conf/jboss-service.xml
<mbean code="org.jboss.ejb.plugins.cmp.jdbc.metada...

The JBoss Microcontainer provides three StructureDeployer implementations out-of-the-box, with relativeOrder values defined for each:
DeclaredStructure: relativeOrder 0
JARStructure: relativeOrder 10000
FileStructure: relativeOrder Integer.MAX_VALUE
At deployment time, the StructureDeployer with lower relativeOrder will be consulted first to determine the structure of a deployment. This means that DeclaredStructure is always called first followed by JARStructure and finally FileStructure .
DeclaredStructure allows you to specify the structure of a deployment, including any nested deployments, using an XML file named jboss-structure.xml placed in the deployment's META-INF directory. For example, the following is jboss-structure.xml for jbossweb.sar , the JBoss Tomcat service:
<?xml version="1.0" encoding="UTF-8"?>
<structu...

The JBoss JARStructure class determines whether a deployment, in the form of a file or a directory, represents a packaged or unpackaged JAR archive. If the deployment is a single file then the filename suffix is checked against the following list. If the deployment is a directory then the same check is performed using the directory name. If a match is found in either case, then the deployment is considered a JAR archive. A top level directory is always considered an unpackaged JAR archive, even when the suffix does not match. .zip - a standard archive .jar - a java archive (defined by the Java SE specification) .ear - an enterprise archive (defined by the Java EE specification) .rar - a resource archive (defined by...
