多吉特：

@WebServlet(urlPatterns = "/") 
public class index extends HttpServlet{
    private static final long serialVersionUID = 1L;
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        request.getRequestDispatcher("/index.jsp").forward(request,response);
    }
}

启动服务器：

WebAppContext webapp1 = new WebAppContext();
webapp1.setResourceBase("src/Pages");
webapp1.setContextPath("/");
webapp1.setDefaultsDescriptor("src/WEB-INF/web.xml");
webapp1.setDescriptor("src/WEB-INF/web.xml");
server.setHandler(webapp1);

getServletContext（）无济于事

请帮助我了解问题所在

添加index.jsp，生成NetBeans 8.1，我不会更改：

<%@page contentType="text/html" pageEncoding="UTF-8"%>

<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">

<f:view>
    <html>
        <head>
            <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
            <title>JSP Page</title>
        </head>
        <body>
            <h1><h:outputText value="Hello World!"/></h1>
        </body>
    </html>
</f:view>


JSP页面
您的index.jsp
正在调用servlet，而servlet正在调用index.jsp
，因此它们有无限循环。更改servlet应该转发的页面
getServletContext().getRequestDispatcher("/page.jsp").forward(request,response);

我确实做了那件事
getServletContext().getRequestDispatcher("/page.jsp").forward(request,response);

正如罗曼C.所建议的，但这并不能单独解决这个问题。我还删除了所有servlet映射
 默认生成jsp NetBeansCan您可以在不转发的情况下从浏览器查看index.jsp？是…如果使用weappcontext或doGet print Writer。
