Response.Write不让写String的参数

Question

String picname = upload.addImage(request, "pic", "headImage");
if(picname != null){
String path = session.getServletContext().getRealPath("/" )+"pic\headImage\"+user.getHeadpic();
upload.deletepic(path);
user.setHeadpic(picname);
loginqianmapper.updateByPrimaryKeySelective(user);
}
Response.Write("window.parent.uploadSuccess("+picname +");");

            The method Write(String) is undefined for the type Response，出这个异常

Answer 1

改成
response.getWriter().write(...);试试
