在尝试交付jsp页面时未发现资源错误

我正在使用部署在jboss (6.0.2 EAP)上的war文件的restasy

我有以下的工作流程:

URL命中呼叫servlet(doGet() method)
这个servlet应该向客户端交付一个jsp页面

JSP页面驻留在WebContent/customFolder
我使用requestDispatcher().forward()方法来调用JSP
forward("/customFolder/name_of_jsp")

问题是，一旦调用forward()方法，浏览器返回404资源未找到错误。

我已经关注了这个论坛上已经发布的一些问题，但无法解决这个问题。

有谁能给我指路吗?

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>

必须交付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);
    }

你的代码:

RequestDispatcher rd = requestContext.getRequestDispatcher(htmlfileName);

你应该改变:

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

如果您使用get方法，如下所示:

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

如果您使用post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。看看下面这些简单的格式:

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

您希望该列表的引用如下链接单击
