<%@ page contentType="text/html;charset=GBK"%>

VERSUS

<%@page contentType="text/html;charset=GBK" pageEncoding="GBK"%>

    ContentType charset

    The contentType charset is how the servlet container which runs the JSP must send to the browser the text generated by the page.

    PageEncoding

    The pageEncoding directive is used to correctly read the JSP from the file system. Since even the JSP is a text but a file is a sequence of bytes on disk, it can be correctly read only knowing the charset to use.

    Then:
