Re: Response encoding problem
Hi - I'm trying to show utf-8 data in the browser from my jsp page.
When the page renders, its character encoding is iso-8859-1, according
to the browser. The http
response headers have the same encoding (iso-8859-1).
Here's what's been done thus far:
1) meta tag set as follows:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
2) jsp page encoding directive issued at the start of the jsp page.
<%@page contentType="text/html; charset=UTF-8"%>
3) Generated jsp page has the following java code, as a consequence:
try {
_jspxFactory = JspFactory.getDefaultFactory();
response.setContentType("text/html; charset=UTF-8");
pageContext = _jspxFactory.getPageContext(this, request, response,
null, false, 8192, true);
application = pageContext.getServletContext();
config = pageContext.getServletConfig();
out = pageContext.getOut();
_jspx_out = out;
...
4) When I save the page as an html file and open it as an html file in
the browser, it renders correctly (due to the meta tag and no http
headers), which is expected.
5) Manually changing the page encoding in firefox results in the page
being rendered correctly.
6) Also set utf-8 in the connector settings in tomcat/conf/server.xml
(for GETs?)
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="8080" minProcessors="5" maxProcessors="75"
URIEncoding="UTF-8" useBodyEncodingForURI="true"
enableLookups="true" redirectPort="8443"
acceptCount="100" debug="0" connectionTimeout="20000"
useURIValidationHack="false" disableUploadTimeout="true" />
7) Set utf-8 in web.xml as follows:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>javaEncoding</param-name>
<param-value>UTF8</param-value>
</init-param>
...
However, the page still shows up as iso-8859-1 (in firefox and IE),
and viewing the response headers using a 3rd party plugin shows the
content-type as ISO-8859-1
Tomcat: 4.1.31
JDK: 1.4.2
What I'm hoping to learn is how to set the http response headers
correctly. It seems that the generated java code is doing the right
thing. However, the response header is still jacked...
Any help will be very, very much appreciated! I've gone through
several articles on Goog as well as the tomcat mailing list... The
brick wall is getting bloodier, and I'm getting woozy from the
pounding...

Also, I have a vague memory that the JSP source itself must be stored in
UTF-8, if there are any non-ASCII characters in it. Might want to check
the archives for that.

I don't know if this helps, but I had a similar problems once, and it
was caused by a filter which was reading a parameter from the request.
This first access set the encoding to 8859-1, overriding all my
following settings.
I would start from this ... hope this helps.
Good luck!

Re: Response encoding problem
Posted by ruphus13 <ru...@gmail.com>.
Thanks for all your help. Here's some more data and an update:
1) The jsp is basically displaying unicode strings from the db. So,
there is no other data other than a directive to print the string from
the db.
2) Running a direct query from the db shows the string correctly. The
db is mysql. The table type is innodb. The charset has been set to
utf-8.
3) Currently, the locale is set as follows:
<% java.util.Locale locale = request.getLocale();
String userLocale = locale.toString(); %>
<fmt:setLocale value = "${userLocale}"/>
When I changed that to force the locale to utf-8, the browser
(firefox) was showing the page encoding as utf-8. The response
headers were utf-8. However, the string now was getting 'double
encoded', and was still showing up jacked.
I will try the filters route, and will try and see what is getting
passed in and out.
Will also try working with a very basic jsp page that just prints out
a static string to see how things are flowing through the app.
Any links on the 'best practices' to follow for such a scenario
(showing utf-8 strings from the db)?
Thanks in advance!

If your JSP page is being included from another servlet, then it won't be
allowed to set the content-type (or charset) of the response. Just a wild
guess here :).
The HTTP/1.1 RFC states that the character encoding of the headers is
iso-8859-1. That is why Tomcat doesn't provide an option to change it.
