Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app :
<project> <modelVersion>4.0.0</modelVersion>...Create a directory named ear under javaee-app . Create pom.xml under ear :
<project> <modelVersion>4.0.0</modelVersion>...Modify pom.xml in the webapp directory so that it looks like this:
<project> <modelVersion>4.0.0</modelVersion> ...Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....

cURL is a command line tool for transferring files with URL syntax. The main purpose and use for cURL is to automate unattended file transfers or sequences of operations. It's really easy to see HTTP headers with curl:
C:\>curl --head http://www.google.com HTTP/1.0 ...or, headers and page together (dump headers to stdout):
$ curl --dump-header - http://www.google.com HTTP/...Download openssl from openssl.org:

It's easiest to use the archetype plugin to start a new Maven project. I'll use struts 1 as example since it's not in the built-in archetypes for archetype:generate . Generate a simple webapp with archetype:generate :
C:\work\maven>mvn archetype:generate -DarchetypeAr...It generates a directory structure like this:
struts1app struts1app/pom.xml struts1app/src...with a simple POM:
<project xmlns="http://maven.apache.org/POM/4.0.0"...Create settings.xml in $HOME/.m2 , add Java.net repository for Java EE dependencies:
<?xml version="1.0" encoding="UTF-8"?> <setting...Add Java EE and Struts dependencies in pom.xml . Note that the Java EE dependency has scope provided , meaning that the web app container provides the jars, therefore we don't need to bundle them with our war fie.
<project xmlns="http://maven.apache.org/POM/4.0.0"...Create a directory named java under main , create the Struts form and...

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 :
