Deploying a jsp web app

Transcript Deploying a jsp web app

jsp
JBoss
• Many servers (like JBoss and Glassfish)
are Tomcat servers.
• The file structures and format for
deployment are the same.
• Where (in what server directory) files get
deployed varies.
• These jsp examples were developed on
JBoss
Webapps with only jsp
• Jsp are compiled and run as if they were servlets by
tomcat, but you write only script code and the container
does the rest.
• Jsp, css and html files will go at the root of the webapp
and WEB-INF will contain just an empty web.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app><!—notice this is an empty tag? -->
</web-app>
Here is my (jsp) samples directory
Creating/Running a jsp for JBoss (or
Tomcat)
Create a directory named MyGreeting
Within the MyGreeting directory, create a subdirectory named WEB-INF (capitalization
matters, so be precise, and that's a dash, not an underscore)
MyGreeting
| +-- HelloWorld.jsp (*)
| +-- WEB-INF
|
+-- web.xml (*)
(*) denotes a file
Create a JSP file named MyGreeting/HelloWorld.jsp
Add the following text to the HelloWorld.jsp file:
<%@ page language="java" %> <HTML> <BODY> <% for (int counter = 1; counter <=
10; counter++) { %> Hello World!<BR> <% } %> </BODY> </HTML>
Create the web.xml file in MyGreeting/WEB-INF/web.xml
Add the following text to web.xml: note – this xml doc is basically empty.
(from code/Chapter1/MyGreeting/WEB-INF/web.xml)
<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd"> <web-app> </web-app>
deployment
Put the directory into Tomcat webapps or create the war file.
To build the war:
Drop to a command line and change to the MyGreeting directory
Use the command-line jar utility, jarring up any jsp files as well as the WEB-INF
dir into a war called MyGreeting:
c:\j2ee\code\Chapter1\MyGreeting> jar cvf MyGreeting.war *.jsp WEB-INF
Note that to jar additional files like html or css you could use
jar cvf MyGreeting.war *.jsp *.html *.css WEB-INF
Or
jar cvf MyGreeting.war *.* WEB-INF
Copy MyGreeting.war to the deploy folder in your JBoss installation (or to
webapps in tomcat):
c:\j2ee\code\Chapter1\MyGreeting> copy MyGreeting.war
c:\j2ee\jboss\deploy\
Start JBoss
Open a web browser and go to http://localhost:8080/MyGreeting/HelloWorld.jsp
A very simple JBoss example

using jsp
• http://www.centerkey.com/jboss/
• 1) Create Work Folder
• Create a folder called "HelloWorld"
separate from your JBoss installation. For
example, the full path of your work folder
could be "C:\Projects\HelloWorld".
• 2) Create Startup Script below (or just navigate to the
bin directory and click the run batch file)
• In the "HelloWorld" folder create a file named
"JBoss.bat" with the following content: JBoss.bat
@echo off
set JAVA_HOME=\Program Files\Java\jdk1.6.0_11
set JBossHome=\Apps\JBoss\jboss-5.0.0.GA
set Path=%JAVA_HOME%\bin;%Path%
cd "%JBossHome%\bin"
run.bat
Write JSP File hi.jsp in the "HelloWorld“ dir
This JSP simply displays a greeting along with the current date and time.
<html><head><title>JSP Test</title>
<%!
String msg = "Hello, World.";
%>
</head>
<body>
<h2><%= msg %></h2>
<%= new java.util.Date() %>
</body></html>
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.
Create WAR Builder & Deployer
• In the "HelloWorld" folder, create a file called "Deploy.bat" as:
Deploy.bat
@echo off
set JAVA_HOME=\Program Files\Java\jdk1.6.0_11
set JBossHome=\Apps\JBoss\jboss-5.0.0.GA
"%JAVA_HOME%\bin\jar.exe" -cvf helloworld.war *.jsp WEB-INF
copy helloworld.war "%JBossHome%\server\default\deploy"
pause
•
This script uses Java's JAR utility to zip up the appropriate contents
into a WAR file.
Test Your Web Page
• Run the "Deploy.bat" file.
In a browser, open
"http://localhost:8080/helloworld/hi.jsp" to
see your web application run.

Remember to build directory
structure with web-inf containing
web.xml and jsp and css at top
level.
Jar into a war file and deploy in
JBoss default server.
A bunch of jsp from the
coreservlets text
• Along with an empty web.xml file, the css file
from above, I packaged a bunch of the simple
jsp examples from coreservlets as a war file and
put them in JBoss. An example shown below.
