jboss下的简单JSP与SERVLET应用部属
1. Write the JSP
Example (uno.jsp) :
<%@ page import="java.text.*,
java.util.*"%>
<HTML>
<BODY>
<%
Date d = new Date();
String hoy = DateFormat.getDateInstance().format(d);
%>
La Fecha de hoy es :
<EM> <%= hoy %> </EM>
</BODY>
</HTML>
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 = WAR name file
Example (application.xml):
<?xml version="1.0" encoding="ISO-8859-1"?>
<application>
<display-name>uno</display-name>
<module>
<web>
<web-uri>uno.war</web-uri>
<context-root>/uno</context-root>
</web>
</module>
</application>
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%serverdefaultdeploy
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-4.0.4catalinacommonlibservlet.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>
<servlet-name>Dos</servlet-name>
<servlet-class>com.servlet.Dos</servlet-class>
</servlet>
</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"?>
<application>
<display-name>dos</display-name>
<module>
<web>
<web-uri>dos.war</web-uri>
<context-root>/dos</context-root>
</web>
</module>
</application>
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%serverdefaultdeploy
11. Run the JBoss-Tomcat server.
12. Test the Servlet. Use the following URL:
http://[IP ADDRESS SERVER]:8080/dos/servlet/Dos
