Hi Lubos,
I received your suggested 'filter' solution a couple of months ago in
response to a problem I was having with tapestry and UTF-8, I didn't use it
afterwards as I just used an image instead of the desired text, but now that
I'm internationalising my web application, I'd like to fix this problem for
once and for all.
I've tried/attempted your solution, but to no avail, perhaps you could take
a quick look at my implementation and check to see that I haven't done
something stupid!
Regards, Brian.
In web.xml (just the relevant entries are shown)
<web-app>
<context-param>
<param-name>PARAMETER_ENCODING</param-name>
<param-value>UTF-8</param-value>
</context-param>
<filter>
<filter-name>meta-filter</filter-name>
<filter-class>com.mycompany.MetaFilter</filter-class>
</filter>
<filter-mapping>
<servlet-name>my_project</servlet-name>
<filter-name>meta-filter</filter-name>
</filter-mapping>
<servlet-mapping>
<servlet-name>my_project</servlet-name>
<url-pattern>/app</url-pattern>
</servlet-mapping>
</web-app>
The filter class I created based on your example . . .
package com.mycompany;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
public class MetaFilter implements Filter {
FilterConfig config;
public void init(FilterConfig config)
{
this.config = config;
}
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse,
FilterChain filterChain) throws IOException,
ServletException {
try {
HttpServletRequest httpServletRequest =
(HttpServletRequest)
servletRequest;
servletRequest.setCharacterEncoding("UTF-8");
servletResponse.setContentType( "text/html;
charset=UTF-8" );
} finally {
//do nothing;
}
}
public void destroy() {
}
}
I'm sure I missing something in the above, the httpServletRequest I create
is never read/used, perhaps you could give me some pointers as to how I
would finish off this class?
Thanks again for all your help . . .

I had the same problem with Tapestry 3.02 and I think it is still in 4.0.
Somehow
Tapestry doesnt' set up content type properly. Looking at html source from
Tapestry,
the <meta> for content type is not the first <meta> but the second <meta>
in
the <header>.
I have read somewhere, that content type <meta> must be the first in
<header> otherwise it is ignore.
I came with workaround. I use web-app <filter> and in that I force utf-8:
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse,
FilterChain filterChain) throws IOException, ServletException
{
try {
HttpServletRequest httpServletRequest = (HttpServletRequest)
servletRequest;
servletRequest.setCharacterEncoding("UTF-8");
servletResponse.setContentType( "text/html; charset=UTF-8" );
It is ugly but it works.
