<%@ taglib uri="http://custom.tag.com/demo" prefix...output:
<html> <body> <p>Hello Tigger!</p> <p>H...With Maven, this is the directory structure:
./src ./src/main ./src/main/resources ./s...There are three files to write: pom.xml :
<project xmlns="http://maven.apache.org/POM/4.0.0"...src/main/java/tagdemo/IterateTag.java :
package tagdemo; import java.io.IOException...src/main/resources/META-INF/demotag.tld :

This example decompresses a gzip compressed file with java.util.zip.GZIPInputStream . The input is assumed to be Base64 encoded after being gzipped (such would be the case when binary data is transmitted within an XML file). You don't need the Base64InputStream if the data is not Base64 encoded.
import java.io.*; import java.util.zip.GZIPInpu...

In a test condition, the XPath expression is evaluated to a boolean value by the rules of the XPath boolean() function, which converts its argument to a boolean as follows: a number is true if and only if it is neither positive or negative zero nor NaN. a node-set is true if and only if it is non-empty. a string is true if and only if its length is non-zero. an object of...

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 .

Apache httpd.conf :
LoadModule python_module modules/mod_python.so ...Python script:
