简单问题出错:Enumeration
cannot be resolved to a type
练习 request.getParameterNames()的用法,
html页面有个form,调用jsp页面
jsp页面
<%@ page contentType= "text/html;charset=gbk "%>
<%@ page import= "javax.util.* "%>
<%
request.setCharacterEncoding( "GBK ") ;
Enumeration enu = request.getParameterNames() ;
%>
运行出错:
An error occurred at line: 5 in the jsp file: /demo08.jsp
Generated servlet error:
Enumeration cannot be resolved to a type
why?????????????????
------解决方案--------------------这是你写的!
<%@ page contentType= "text/html;charset=gbk "%>
<%@ page import= "javax.util.* "%>
这是我写的:
<%@ page language= "java " import= "java.util.* " pageEncoding= "GBK "%>
这行就没用了request.setCharacterEncoding( "GBK ") ;
改改试试
------解决方案-------------------- <%@ page import= "javax.util.* "%>
改成
<%@ page import= "java.util.* "%>
------解决方案--------------------你查一下JDK的文档就知道了,没有javax.util包,只有java.util
http://java.sun.com/j2se/1.5.0/docs/api/
------解决方案--------------------你的jdk版本是不是太低了?
