java - 爆发 war 中的嵌入式jetty服务器

Question

在通过jetty成功运行WAR之后，我尝试将jetty服务器嵌入到我的网络应用程序中。它是一个由 servlet 组成的普通 java 应用程序。我使用了分解的 WAR 目录(WARless)。

但我遇到以下异常。

嵌入jetty服务器代码

    package com.jetty;

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

    public class RunJetty {

    public RunJetty() {
    }
    public static void main(String[] args) {
    Server server=new Server(8080);
    WebAppContext wac = new WebAppContext();
    wac.setResourceBase("C:/Users/User/j2ee/workspace/CLient1");
    wac.setDescriptor("C:/Users/User/j2ee/workspace/CLient1/WebContent/WEB-INF/web.xml");
    wac.setContextPath("/");
    wac.setParentLoaderPriority(true);
    server.setHandler(wac);
    try {
        server.start();
        server.join();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    }

    }

Servlet 代码

    package com.jetty;

    import java.io.IOException;

    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;

    import org.omg.CORBA.RepositoryIdHelper;

    public class ClientServlet extends HttpServlet {

    private static final long serialVersionUID = 8120079003868426157L;
    private String greeting="Hello World";

    public ClientServlet(){}
    public ClientServlet(String greeting)
    {
    this.greeting=greeting;
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
    {
    response.setContentType("text/html");
    response.setStatus(HttpServletResponse.SC_OK);
    response.getWriter().println("<h1>"+greeting+"</h1>");

    }

    }

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>kajh</display-name>

    <servlet>
    <description></description>
    <display-name>ClientServlet</display-name>
    <servlet-name>ClientServlet</servlet-name>
    <servlet-class>ClientServlet</servlet-class>
    </servlet>
    <servlet-mapping>
    <servlet-name>ClientServlet</servlet-name>
    <url-pattern>/ClientServlet</url-pattern>
    </servlet-mapping>
    </web-app>

此外，我想在我的servlet 中使用response.sendRedirect。比如，

      public class ClientServlet extends HttpServlet {

/**
 * 
 */
private static final long serialVersionUID = 8120079003868426157L;
private String greeting="Hello World";

public ClientServlet(){}
public ClientServlet(String greeting)
{
    this.greeting=greeting;
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
    response.setContentType("text/html");
    response.sendRedirect("http://localhost:8080/CLient1/index.html");

}
}

请帮忙!我永远困在这个问题上。预先感谢您!

此外，我还添加了应用程序的文件夹结构，以便更好地理解

我认为 servlet-class 应该是

<servlet-class>com.jetty.ClientServlet</servlet-class>

编辑:使其也显示代码格式。
