Deploying Hello World Application on Apache Geronimo Application Server

     

In this section we will develop Hello World JSP application and test on the Apache Geronimo Application Server.

Please follow the following steps to easily develop and deploy the application on the server.

Step 1:

Create the following directory structure in a directory to place the application artifacts correctly

Directory Structure of Web Component
 /hello/
   HelloWorld.jsp
  WEB-ING
   web.xml
geronimo-web.xml
   classes
     servlet classes
   lib
     jar files
    

Here is the screen shot of directories that you need to create:

 

Alternately you can download the code and directory structure from following url:

Step 2:

Create jsp file under hello directory and add the following code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
 <HEAD>
  <TITLE>Hello World Jsp Example</TITLE>
 </HEAD>

 <BODY>
<h1>Hello World!</h1>  
<p><%=new java.util.Date()%></p>
 </BODY>
</HTML>

Step 3: 

Create geronimo-web.xml file into /hello/WEB-INF/ directory and copy the following code:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-2.0.1">
  <environment>
  <moduleId>
  <groupId>org.apache.geronimo.samples</groupId>
  <artifactId>HelloWorldApp</artifactId>
  <version>2.1</version>
  <type>war</type>
  </moduleId> 
  </environment>
  <context-root>/hello</context-root>
</web-app>

Step 4: 

Finally we have to create the web.xml file into /hello/WEB-INF/ directory with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  
  <welcome-file-list>
  <welcome-file>HelloWorld.jsp</welcome-file>
  </welcome-file-list>

</web-app>

Step 5:

To create the deployable war file use the following command:

jar -cvf ../hello.war *

Here the output 

C:\gerionimo\HelloWorldJsp\hello>jar -cvf ../hello.war *
added manifest
adding: HelloWorld.jsp(in = 222) (out= 166)(deflated 25%)
adding: WEB-INF/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/geronimo-web.xml(in = 430) (out= 228)(deflated 46%)
adding: WEB-INF/lib/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/web.xml(in = 430) (out= 223)(deflated 48%)

C:\gerionimo\HelloWorldJsp\hello>

Step 6: 

Now we are ready to deploy the application. To deploy the application copy hello.war into deploy directory of the Apache Geronimo application server (into directory C:\geronimo-tomcat6-javaee5-2.1\deploy).

Application server will auto deploy the application.

Step 7:

Open the browser and type http://localhost:8080/hello/. Your browser should show the Hello World message with the current date as shown below:

 Download the source code of the application

In the next section we will deploy Servlet on the Apache Geronimo Application server.
