解决方案 »

  1.   

    贴下jsp页面的代码啊  这个看不出来
      

  2.   

    这是jsp代码 就一句话
    <%@npage language="java" pageEncoding="GB18030"%>
    <%@ntablib prefix="mm" nuri="/mytaglib"%>
    <%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    %><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
      <head>
        <base href="<%=basePath%>">
        
        <title>My JSP 'hello.jsp' starting page</title>
        
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">    
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->  </head>
      
      <body>
        <p><mm:hello/>:lin!</p> 
      </body>
    </html>
      

  3.   

    mytaglib.tld<?xml version="1.0" encoding="utf-8"?> 
    <taglib> 
    <tlib-version>1.0</tlib-version> 
    <jsp-version>1.2</jsp-version> 
    <short-name>mytaglib</short-name> 
    <uri>/mytaglib</uri> 
    <tag> 
    <name>HelloTag</name> 
    <tag-class>tag.HelloTag</tag-class> 
    <body-content>empty</body-content>  
    </tag> 
    </taglib> web.xml<?xml version="1.0" encoding="GB18030"?>
    <web-app xmlns="http://java.sun.com/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
       version="2.5"> 
    <taglib> 
         <taglib-uri>/mytaglib</taglib-uri> 
         <taglib-location>/WEB-INF/mytaglib.tld</taglib-location> 
    </taglib>  </web-app>
      

  4.   

    去掉<base href="<%=basePath%>">这行试试
