I want a simple example of JSP or servlet

[sheldon]

Hi,
I just install the jboss and don't know how to use it.

The examples on jboss website doesn't work for me.

Can anyone give me a single example to run it. Please include every file and the compile command.

I am so appreciate for your help.

[joelvogt]

step 1, write a j2ee app
step 2, put it in jboss/deploy

If you want a simple app, make a directory foo.war in jboss/deploy and put a jsp foo.jsp inside.

Your foo.jsp can have the following text :

foo

then go to http://localhost:8080/foo/foo.jsp

and you will see the message foo.

I can include these files as an attachement if you don't want to write the foo.jsp yourself.

Sheldon,
Here is the procedure for JSPs :

1. Write the JSP
Example (uno.jsp) :


<%@ page import="java.text.*,
java.util.*"%>



<%
Date d = new Date();
String hoy = DateFormat.getDateInstance().format(d);
%>
La Fecha de hoy es :
<%= hoy %>



2. Create a WAR file with JSP file. Use the following command :

jar -cvfM uno.war uno.jsp


3. Create an application.xml file in META-INF directory. You need set the correct values in <web-uri> tag and <context-root> tag.

web-uri = WAR name file

Example (application.xml):


<?xml version="1.0" encoding="ISO-8859-1"?>

<display-name>uno</display-name>


<web-uri>uno.war</web-uri>
<context-root>/uno</context-root>




4. Create a EAR file with WAR file and application.xml file. Use the following command :

jar -cvfM uno.ear uno.war META-INF

5. Copy this EAR file in %JBOSS_HOME%\server\default\deploy

6. Run the JBoss-Tomcat server.

7. Test the JSP. Use the following URL:

http://[IP ADDRESS SERVER]:8080/uno/uno.jsp

The first time is slow because JBoss-Tomcat compiles the JSP file but the next time is fast.


HERE IS THE PROCEDURE FOR SERVLETS :


1. Write your servlet. For example

Dos.java

package com.servlet;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Dos extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {

PrintWriter out = response.getWriter();
out.println("Hello World");
}
}

2. Compile your servlet. Use the following command :

javac -classpath d:\jboss-3.0.1_Tomcat-4.0.4\catalina\common\lib\servlet.jar Dos.java

3. Create a WEB-INF directory.

4. Create a classes directory in WEB-INF directory and copy Dos.class.


WEB-INF (Subdirectory)
I
I
classes (Subdirectory) ---
I
I
com (subdirectory)----
I
I
servlet (subdirectory)
I
I
Dos.class (Java Class)

5. Create a web.xml file in WEB-INF directory.

For example:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>

<servlet-name>Dos</servlet-name>
<servlet-class>com.servlet.Dos</servlet-class>

</web-app>

6. Create a META-INF directory.

7. Create an application.xml file in META-INF directory.

For example:

application.xml

<?xml version="1.0" encoding="ISO-8859-1"?>

<display-name>dos</display-name>


<web-uri>dos.war</web-uri>
<context-root>/dos</context-root>




8. Create a WAR file. Use the following command :

jar -cvfM dos.war WEB-INF

9. Create a EAR file. Use the following command :

jar -cvfM dos.ear dos.war META-INF

10. Copy the EAR file in %JBOSS_HOME%\server\default\deploy

11. Run the JBoss-Tomcat server.

12. Test the Servlet. Use the following URL:

http://[IP ADDRESS SERVER]:8080/dos/servlet/Dos
