乱码 ：javascript中uil带参数跳到action中接收 为乱码 解决

javascript里面 
function removeUser(ddid,className){ 
var url=encodeURI("removeUser.action?user.id.id="+ddid+"&   className="+className   ); 
var falg=confirm("确认删除用户，会删除用户下的考试成绩！！","确认","取消"); 
if(falg){ 
location.url; < /strong>
} 
} 
action 里面： 
public void setClassName (String className) { 
HttpServletRequest request=ServletActionContext.getRequest(); 
String linename=""; 
try { 
linename = new String(request.getParameter("className").getBytes("ISO-8859-1"),"UTF-8"); 
} catch (UnsupportedEncodingException e) { 
// TODO Auto-generated catch block 
e.printStackTrace(); 
} 
this.className =linename; 
}
