					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
   url for a similar 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.

        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.
