乱码问题~~求救 ！！！
问一下　如果在jsp中用form1.action= "UserManager.do?do=getUser&username=张三 "　　在action中收到的String username=request.getParameter( "username ") 是乱码　　为什么？？？？？

[解决办法]
string = new String( string.getBytes( "iso-8859-1 "), "GB2312 ")
[解决办法]
或者也可以这样：String username=request.getParameter( "username ")==null? " ":new String(request.getParameter( "username ").getBytes( "iso-8859-1 "));
