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>
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
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 offset JAVA_HOME=\Program Files\Java\jdk1.6.0_11set JBossHome=\Apps\JBoss\jboss-5.0.0.GAset 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 offset JAVA_HOME=\Program Files\Java\jdk1.6.0_11set JBossHome=\Apps\JBoss\jboss-5.0.0.GA"%JAVA_HOME%\bin\jar.exe" -cvf helloworld.war *.jsp WEB-INFcopy 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.

Jar into a war file and deploy in JBoss default server. Css for this example
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.
