Different document headers and DTD locations make the page inaccessible

Example:

<? XML version = "1.0" encoding = "GBK"?> // Document Header

<% @ Page Language = "Java" contenttype = "text/html; charset = GBK"
Pageencoding = "GBK" errorpage = "/common/error. jsp" %>
<% @ Include file = "/common/taglib. jsp" %>

<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> // DTD

 

 

The above is the correct form, if it is the following

<? XML version = "1.0" encoding = "GBK"?> // Document Header

<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> // DTD

<% @ Page Language = "Java" contenttype = "text/html; charset = GBK"
Pageencoding = "GBK" errorpage = "/common/error. jsp" %>
<% @ Include file = "/common/taglib. jsp" %>

When accessing the page, the browser will pause and cannot access the page.
