多双引号问题

 

<page:page

            url="<%=request.getAttribute("url").toString()%>"

            page="<%=request.getAttribute("page").toString()%>"

            sum="<%=request.getAttribute("sum").toString()%>" />

 

 

上面自定义标签引用的时候报错了：

 

解决方案有两个：

1、把双引号改为单引号：

         <page:page url="***" page="***" sum="***" />

         <page:page url='***' page='***' sum='***' />

2、更改Tomcat版本：

         测试发现，Tomcat 6.0.32版本和5.5.33均出现此问题，改为Tomcat 5.5.23版本问题解决，其他版本未试过！

 

 

错误信息：
