我制作了一个带有嵌入式Jetty的RCP插件,步骤如下:
1)在plugin.xml -> Dependencies中,我添加了以下内容:
org.eclipse.equinox.http.jetty
org.eclipse.equinox.http.registry
org.mortbay.jetty.server
javax.servlet
2)我在plugin.xml->扩展中添加了一个Servlet扩展点(org.eclipse.equinox.http.registry.servlet)。
class: TemperatureServlet
alias:/temperature
TemperatureServlet 的代码如下:
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class TemperatureServlet extends HttpServlet {
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
System.out.println("doGet Called");
resp.sendRedirect("Convertor.jsp");
}
}
这个文件名为Convertor.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

</head>
<body>
<f:view>
<h:form>
<h:panelGrid columns="2">
<h:outputLabel value="Celsius"></h:outputLabel>
<h:inputText value="#{temperatureConvertor.celsius}"></h:inputText>
</h:panelGrid>
<h:commandButton action="#{temperatureConvertor.celsiusToFahrenheit}" value="Calculate"></h:commandButton>
<h:commandButton action="#{temperatureConvertor.reset}" value="Reset"></h:commandButton>
<h:messages layout="table"></h:messages>
</h:form>
<h:panelGroup rendered="#{temperatureConvertor.initial!=true}">
<h3> Result </h3>
<h:outputLabel value="Fahrenheit "></h:outputLabel>
<h:outputLabel value="#{temperatureConvertor.fahrenheit}"></h:outputLabel>
</h:panelGroup>
</f:view>
</body>
</html>
文件 faces-config.xml 包含:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
<managed-bean>
<managed-bean-name>temperatureConvertor</managed-bean-name>
<managed-bean-class>hellojsf.TemperatureConvertor</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
</faces-config>
我的插件具有以下层次结构:
plugin-name
---src
------class package
---------Activator.java
---------Application.java
---------ApplicationActionBarAdvisor.java
---------ApplicationWorkbenchWindowAdvisor.java
---------Perspective.java
---------TemperatureConvertor.java
---------TemperatureServlet.java
---META-INF
------MANIFEST.MF
---resources
-------WebContent
----------WEB-INF
-------------faces-config.xml
-------------web.xml
----------Convertor.jsp
---plugin.xml
在 Activator 类中的 start() 方法中,我这样启动了 Web 服务器:
public void start(BundleContext context) throws Exception {
super.start(context);
plugin = this;
Bundle bundle = Platform.getBundle("org.eclipse.equinox.http.registry");
if (bundle.getState() == Bundle.RESOLVED) {
bundle.start(Bundle.START_TRANSIENT);
}
Dictionary settings = new Hashtable();
settings.put("http.enabled", Boolean.TRUE);
settings.put("http.port", 8080);
settings.put("http.host", "0.0.0.0");
settings.put("https.enabled", Boolean.FALSE);
settings.put("context.path", "/");
settings.put("context.sessioninactiveinterval", 1800);
try {
JettyConfigurator.startServer(PLUGIN_ID + ".jetty", settings);
} catch (Exception e) {
e.printStackTrace();
}
}
我已经在这个插件中添加了以下库:
- JSTL: javax.servlet.jsp.jstl-1.2.1-javadoc.jar; javax.servlet.jsp.jstl-api-1.2.1-javadoc.jar
- JSF 2.0 (Apache MyFaces JSF Core-2.0 API 2.0.2)
例如,当我定义扩展org.eclipse.equinox.http.registry.servlets时,我可以做什么? class:javax.faces.webapp.FacesServlet alias:/*.jsp(所有*.jsp文件都由FacesServlet处理)?
非常感谢,如果问题很傻,请原谅,因为我是一个新手,对于RCP插件、Jetty和JSF领域不熟悉。
