There are two distinct ways to process XPath: with namespace and without namespace. The code is different depending on whether the parser is namespace aware. Code without namespace:
import java.io.*; import javax.xml.parsers.*; ...code with namespace:
import java.io.*; import java.util.Iterator; ...XML without namespace:
<?xml version="1.0" encoding="UTF-8" standalone="n...XML with namespace:
<?xml version="1.0" encoding="UTF-8" standalone="n...The same XPath expression works for both XML files when the parser is not namespace aware. When the parser is namespace aware, you have to adjust the XPath accordingly depending on whether the XML has namespace declarations: " /test-license/licensee/name/text() " works for the XML file without namespace, while " /p:test-license/p:licensee/p:name/text() " works for the XML file with namespace.

This is an odd-ball content provider in that it doesn't provide database records, but provides a resource as a stream. It can be used to provide media files or XML resources. Start the project with:

This is built upon the simple test application for JSTL , which contained a single servlet and a single JSP page. If I want to use it to test all available JSTL tags, the servlet and JSP page would be too complicated. Instead, I want to group the JSTL tags into separate JSP pages and display each group based on the requested URL. For example, if the URL ends with /CoreBasic , I'll display a page that contains the basic core tags; if the URL ends with /I18N , I'll display a page that contains the internationalization tags (e.g., <fmt:message> ). Furthermore, I want to delegate the handling of each group of tags to separate Java classes. This is the application I'll use for the...

In this note I'll show you how to create and package a JSP custom tag. The purpose of this tag is to display a random splash image for a home page, among a set of images. We should be able to add or delete candidate splash images from the WAR archive without the need to change the JSP. This is the intended use of the tag:
<%@ taglib uri="http://custom.tag.com/demo" prefix...In the above example you provide a set of images named splash*.png (e.g., splash1.png, spalsh2.png, ...), and the tag will pick a random one to display when the JSP is rendered. Let's get started. I'll use Maven for this purpose. Create the standard Maven directory structure
./pom.xml ./src ./src/main ./src/main/jav...pom.xml
package tagdemo; import java.util.ArrayList......

This is a script to tail a log file through the web browser. It uses AJAX, apache web server, mod_python, UNIX utilities tail (requires the --lines switch) and wc . The log file may reside on the web server or any other host accessible from the web server through SSH. Although it's written in python, it should be easy to port to other languages such as Perl. Apache httpd.conf :
LoadModule python_module modules/mod_python.so ...Python script:
