// import org.apache.commons.lang3.StringEscapeUti...

This is an example that uses the XSLTProcessor jQuery plugin for client side XSLT. Unfortunately it didn't work in IE or Chrome. It worked in Firefox but somehow disable-output-escaping="yes" was ignored.

I had a need to use Ajax to get a response from the server and conditionally render the results based on a status code. Additionally, I need to update multiple areas on the page from the results of one request. The code presented here uses jQuery and an XML response with CDATA sections to achieve that goal. Server side code (perl cgi):
#!C:/perl/bin/perl.exe ## ## redirect ##...The HTML page:

This is a simple web application with a single servlet and a single JSP page. It is intended to be a test bed for JSTL tags. You may want to store all syntax, rules, and exceptions in your head, but in my opinion nothing beats a simple test program that allows you play with it all you want. So here it is (build with Maven ). Prerequisites: Maven: http://maven.apache.org/ . You don't need any prior knowledge of Maven, but you need to install the binary. JBoss: http://jboss.org/jbossas/downloads/ , or Tomcat: http://tomcat.apache.org/ if you don't run the SQL tests. You need to know how to deploy a web application (shh! Don't tell your boss it's just copying a file to the deployment folder). Steps: The directory...

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......

Your code will be syntax highlighted when you specify the language of your code with the BBcode code tag:
[code=lang] Your code here [/code]where "lang" is the language of your code. For example, the following Perl code
#!/usr/bin/perl print "Hello World!\n";is rendered with:
[code=perl] #!/usr/bin/perl print "Hel...The following are supported languages and their corresponding names for BBcode:
Apache conf: apacheconf, aconf, apache Bash...The full list is available from http://pygments.org/ , which is our backend engine for syntax highlight rendering.

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:
import time, os from os.path import basename ...
