Deploying JSP Web App on Jboss Application Server on Linux
Here is step by step procedure to deploy a Simple JSP Web App on JBoss Application Server:
The steps are designed for Linux OS. For windows version please check here
1) Install Java
Obtain Java by clicking the "Download" button for Java SE Development Kit (JDK) 6 Update 14 at:
http://java.sun.com/javase/downloads/
Unzip the file into "~/java/" directory.
2) Install JBoss Application Server
Go to the JBoss download page at:
http://www.jboss.org/jbossas/downloads
Locate version 4.2.2.GA, and follow the "Download" link to get the "jboss-5.1.0.GA.zip" file.
Unzip the file into "~/java/" directory.
cd ~/java/lsjboss-4.2.2.GA jdk1.5.0_19
3) Create Work Folder in your personal projects directory
cd ~/projectsmkdir Helloworld4) Create JBoss Startup Script: Just copy the below content into jboss file and make it executable.
#!/bin/bash
#
# Starts the jboss application server
# JAVA HOME
JAVA_HOME="/home/sheeju/java/jdk1.5.0_19/"
JBOSS_HOME="/home/sheeju/java/jboss-4.2.2.GA"
prog="jboss"
start() {
echo -n $"Starting $prog: "
$JBOSS_HOME/bin/run.sh
}
case "$1" in
start)
start
;;
*)
echo $"Usage: $0 {start}"
exit 1
esac
exit $?
This script will launch JBoss.
5) Write JSP File
Also in the "HelloWorld" folder, create a file named "index.jsp" as:
index.jsp
<html><head><title>JSP Test</title>
<%!
String message = "Hello, World.";
%>
</head>
<body>
<h2><%= message%></h2>
<%= new java.util.Date() %>
</body></html>
This JSP simply displays a greeting along with the current date and time.
6) Create Deployment Descriptor
In the "HelloWorld" folder, create a sub folder called "WEB-INF", and in that folder create a file named "web.xml" as:
web.xml
<web-app>
<display-name>Hello World</display-name>
</web-app>
The deployment descriptor provides information to JBoss about your web application.
8) Create WAR Builder & Deployer
In the "HelloWorld" folder, create a shell script named "deploy" as:
#!/bin/bash
#
# Starts the jboss application server
# JAVA HOME
JAVA_HOME="/home/sheeju/java/jdk1.5.0_19/"
JBOSS_HOME="/home/sheeju/java/jboss-4.2.2.GA"
prog="jboss"
start() {
echo -n $"Starting $prog: "
$JBOSS_HOME/bin/run.sh
}
case "$1" in
start)
PROJECT=$2
echo -n $"Deploying Project $PROJECT "
$JAVA_HOME/bin/jar -cvf $PROJECT.war *
cp $PROJECT.war $JBOSS_HOME/server/default/deploy/
;;
*)
echo $"Usage: $0 {start} {
exit 1
esac
exit $?
This script uses Java's JAR utility to zip up the appropriate contents into a WAR file.
9) execute deploy command
10) Test Your Web Page
In a browser, open "http://localhost:8080/HelloWorld/index.jsp" to see your web application run.
Now explore the JBoss console at "http://localhost:8080". Click on "JBoss Web Console" and expand "J2EE Domains", "jboss.management.local", and "JBoss". Select "helloworld.war" to see information about your web application.

Alternative for putty?
The tool that I use most on my windows box is putty. I've always looked for an alternative since it lacks some features like tabbed sessions, Edit display settings such as the indent colors etc..
Poderosa (funny name :)) is an alternative which is kind off good, and has the features which is similar to Terminator in linux, the important and nice features are
1. Tabbed sessions
2. Split windows horizontally and vertically.
3. Editing display colors etc..
This software requires Microsoft .NET Framework 2.0.
