大家好，

我只是使用一个示例尝试一个嵌入式Jetty JSP的示例   显示在网站上。

主要具有以下依赖性：

启动服务器的主程序：

        <url-pattern>*.XSP</url-pattern>
    </servlet-mapping>
</web-app>

它也有一个jsp页面，我在其中导入了这样的Jetty Server。

example.jsp
              Java Code Geeks片段-示例JSP页面

当前日期是：<％= new java.util.Date（）％>服务器   版本：<％= org.eclipse.jetty.server.Server.getVersion（）   ％>

问题是我无法弄清为什么这个jsp页面在类路径中已经设置后却找不到org.eclipse.jetty.server.Server。

尝试调用此页面时出现以下错误。

package com.javacodegeeks.snippets.enterprise.jettyjsp;

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;

public class JettyJspExampleMain {

    public static void main(String[] args) throws Exception {

        // 1. Creating the server on port 8083
        Server server = new Server(8083);

        // 2. Creating the WebAppContext for the created content
        WebAppContext ctx = new WebAppContext();
        ctx.setResourceBase("src/main/webapp");
        ctx.setContextPath("/jetty-jsp-example");

        //3. Including the JSTL jars for the webapp.
        ctx.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern",".*/[^/]*jstl.*\\.jar$");

        //4. Enabling the Annotation based configuration
        org.eclipse.jetty.webapp.Configuration.ClassList classlist = org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(server);
        classlist.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration", "org.eclipse.jetty.plus.webapp.EnvConfiguration", "org.eclipse.jetty.plus.webapp.PlusConfiguration");
        classlist.addBefore("org.eclipse.jetty.webapp.JettyWebXmlConfiguration", "org.eclipse.jetty.annotations.AnnotationConfiguration");

        //5. Setting the handler and starting the Server
        server.setHandler(ctx);
        server.start();
        server.join();

    }
}

任何建议或帮助将不胜感激。
