Question

我正在使用部署在jboss（6.0.2 EAP）

上的war文件的resteasy工作

我有以下工作流程：

网址匹配称为servlet(doGet() method)
这个servlet应该将jsp页面传递给客户端

JSP页面位于WebContent/customFolder

我使用requestDispatcher().forward()方法来调用JSP

forward("/customFolder/name_of_jsp")
jsp有一个表单，其action属性指向另一个servlet

问题是，一旦调用forward()方法，浏览器就会返回404资源未找到错误。

我已经关注了此论坛上已发布的一些问题，但无法解决此问题。

任何人都可以指导我。

编辑： JSP页面：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1" import="javax.servlet.*,java.lang.String"%>
<!DOCTYPE html> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Password Reset Page</title>

</head>
<body>
<form method="GET" action="Resteasy">
<%!String userId;%>
<%userId = (String)getServletContext().getAttribute("userid"); %>
<p>User Id:<%= userId %></p>
Password: <input type="password" name="pwd" id="pass">
<br>
Confirm Password: <input type="password" name="rePwd" id ="c_pass" onblur="confirmPass()"><br>
<script type="text/javascript">
    function confirmPass() {
        var pass = document.getElementById("pass").value
        var confPass = document.getElementById("c_pass").value
        if(pass != confPass) {
            alert('Wrong confirm password !');
            document.getElementById("c_pass").focus();
        }
    }
</script>
<input type="submit" value="Submit">
</form> 
</body>
</html>

必须提供jsp的servlet：

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        log.info("Received request for popup jsp page");

        String userId = request.getParameter("userid");
        String utc = request.getParameter("utc");

        log.info("Recieved userid = "+ userId);
        log.info("Received utc is = "+ utc);


        ServletContext requestContext = request.getServletContext();
        requestContext.setAttribute("userid", userId);
        requestContext.setAttribute("UTC", utc);


        String htmlfileName = null; 


        try {

            htmlfileName =   new DeltaPropertyHandler(
                    DeltaConstants.LINK_HTML_FILE).getPropertyValue(DeltaConstants
                            .USER_PASSWORD_RESET_HTML);
            File file = new File(requestContext.getRealPath(htmlfileName));
            if(file.exists()){log.debug("file exists!!");}
            else{log.warn("file does mot exist");}

        } catch (Exception e) {

            log.error("failed to present the jsp page " + e.getMessage());
        }
       log.info("File name is "+htmlfileName);

       RequestDispatcher rd = requestContext.getRequestDispatcher(htmlfileName);

       rd.forward(request, response);

    }

Answer 1

您的代码：

RequestDispatcher rd = requestContext.getRequestDispatcher(htmlfileName);

你应该改变：

RequestDispatcher rd = requestContext.getRequestDispatcher(programname.jsp);

如果您使用获取方法如下：

RequestDispatcher view=request.getRequestDispatcher(forward);
            view.forward(request, response);

如果您使用发布方法，如：

private static String LIST_USER="/listUser.jsp";

        RequestDispatcher view=request.getRequestDispatcher(LIST_USER);
        request.setAttribute("users", dao.getAllUsers());
        view.forward(request, response);

用户将从此格式引用。只需看看简单格式如下：

  A.jsp> conntroller.java > dao.java>dbUtil.java

您希望该列表的引用如下所示 link to click

尝试传递jsp页面时找不到资源错误
