When I access utf8-test1.jsp on GlassFish, I get this response:
Content-Type: text/html;charset=ISO-8859-1
whereas on Tomcat 6, I get:
Content-Type: text/html
"charset=ISO-8859-1" is missing from the Content-Type returned
by Tomcat.
Tomcat may be compliant with Servlet 2.0, but it is *not* compliant
with Servlet 2.5.
In Servlet 2.5, ServletResponse#setCharacterEncoding was enhanced
as follows:
* <p>Containers must communicate the character encoding used for
* the servlet response's writer to the client if the protocol
* provides a way for doing so. In the case of HTTP, the character
* encoding is communicated as part of the <code>Content-Type</code>
* header for text media types.
and ServletResponse#getWriter was amended as follows:
* If the response's character encoding has not been
* specified as described in <code>getCharacterEncoding</code>
* (i.e., the method just returns the default value
* <code>ISO-8859-1</code>), <code>getWriter</code>
* updates it to <code>ISO-8859-1</code>.
for this reason:
Specifying iso-8859-1 explicitly for text media types is necessary
because many clients don't follow the HTTP spec in applying this
default - they often use a default encoding based on the locale
they're running in or based on a user preference. By telling these
clients explicitly what we're really using we increase our chances of
having the text processed or displayed correctly.
As you can see, GlassFish follows the Servlet 2.5 spec, whereas Tomcat
does not. It is time that a test for this issue is added to the Servlet
compliance
suite, in which case we would not have had this discussion.
Why can't you add this page directive:
<%_at_page contentType="text/html;charset=utf8"%>
to your JSPs, as you did for utf8-test2.jsp?
You could actually declare this page directive in a JSP prelude,
in which case you would not have to declare it on each and every JSP.
