本文介绍了一个简单的Portlet应用程序的创建过程，包括项目结构、关键文件配置如portlet.xml和web.xml，以及如何在Pluto Portal中部署和配置该应用。

一、文件目录结构如下：

├─libs
│      portlet-api_2.0_spec-1.0.jar
├─src
│  └─hello
│          HelloPortlet.java
└─WebContent
    └─WEB-INF
        │  portlet.xml
        │  web.xml
        ├─classes
        │  └─hello
        │          HelloPortlet.class

1.HelloPortlet.java

package hello;

import java.io.IOException;
import java.io.PrintWriter;

import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.PortletURL;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

public class HelloPortlet extends GenericPortlet {
	protected void doEdit(RenderRequest request, RenderResponse response) throws PortletException, IOException {
		response.setContentType("text/html");
		PrintWriter writer = new PrintWriter(response.getWriter());
		writer.println("You're now in Edit mode.");
	}

	protected void doHelp(RenderRequest request, RenderResponse response) throws PortletException, IOException {
		response.setContentType("text/html");
		PrintWriter writer = new PrintWriter(response.getWriter());
		writer.println("You're now in Help mode.");
	}

	protected void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException {
		response.setContentType("text/html");
		PrintWriter writer = new PrintWriter(response.getWriter());
		writer.println("You're in View mode.<br>");
	}

}

2.portlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<portlet-app xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0"
	xsi:schemaLocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd">
	<portlet>
		<portlet-name>HelloPortlet</portlet-name>
		<display-name>Hello Portlet</display-name>
		<portlet-class>hello.HelloPortlet</portlet-class>
		<supports>
			<mime-type>text/html</mime-type>
			<portlet-mode>VIEW</portlet-mode>
			<portlet-mode>EDIT</portlet-mode>
			<portlet-mode>HELP</portlet-mode>
		</supports>
		<portlet-info>
			<title>Hello, This is my first portlet application</title>
		</portlet-info>
	</portlet>
</portlet-app>

3.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<display-name>pa2</display-name>

	<servlet>
		<servlet-name>HelloPortlet</servlet-name>
		<servlet-class>org.apache.pluto.container.driver.PortletServlet</servlet-class>
		<init-param>
			<param-name>portlet-name</param-name>
			<param-value>HelloPortlet</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>HelloPortlet</servlet-name>
		<url-pattern>/PlutoInvoker/HelloPortlet</url-pattern>
	</servlet-mapping>
</web-app>

二、修改文件pluto-2.0.3\webapps\pluto\WEB-INF\pluto-portal-driver-config.xml,添加如下内容

    <page name="HelloWorld" uri="/WEB-INF/themes/pluto-default-theme.jsp">
      <portlet context="/pa2" name="HelloPortlet"/>
    </page>

三、启动pluto-2.0.3
