Static HTML Text in JSP Page in Standard Syntax

This section provides a tutorial example to test how non-ASCII characters entered as static text in JSP pages in standard syntax are handled by the JSP server and returned to Web browsers.

In the second test, the static text is inserted into a JSP page in standard syntax:

<%@ page contentType="text/html; charset=gb2312" %>
<!-- StaticGB2312.jsp
 - Copyright (c) 2006 HerongYang.com. All Rights Reserved.
-->
</html>
</body>
<p>
GB2312-binary: &#xCBB5;&#xC3F7;=(0xCBB5C3F7)<br/>
GB2312-#xHEX: &#xCBB5;&#xC3F7;<br/>
GB2312-\uHEX: \uCBB5\uC3F7<br/>
Unicode-binary: &#x8bf4;&#x660e;=(0x8bf4660e)<br/>
Unicode-#xHEX: &#x8bf4;&#x660e;<br/>
Unicode-\uHEX: \u8bf4\u660e<br/>
Unicode-UTF8: 说明=(0xE8AFB4E6988E)<br/>
</p>
</body>
</html>

If you view this page in IE, you will that see both GB2312-binary line and Unicode-#xHEX line are displayed correctly. Here is the explanation:

To approve the above explanation, here is the related lines of the generated Java class file:

   ...
   response.setContentType("text/html; charset=gb2312");
   ...
   out.write("GB2312-binary: &#xCBB5;&#xC3F7;=(0xCBB5C3F7)<br/>\r\n");
   out.write("GB2312-#xHEX: &#xCBB5;&#xC3F7;<br/>\r\n");
   out.write("GB2312-\\uHEX: \\uCBB5\\uC3F7<br/>\r\n");
   out.write("Unicode-binary: &#x8bf4;&#x660e;=(0x8bf4660e)<br/>\r\n");
   out.write("Unicode-#xHEX: &#x8bf4;&#x660e;<br/>\r\n");
   out.write("Unicode-\\uHEX: \\u8bf4\\u660e<br/>\r\n");
   out.write("Unicode-UTF8: ??=(0xE8AFB4E6988E)<br/>\r\n");
   ...

If you change the "charset" to utf-8, I am sure Unicode-UTF8 line will be displayed correctly. You know why.

By the way, "charset" can also be specified as "pageEncoding" in the "page" directive statement.
