Latest news!
I find out that after removing resp.setContentType("text/html"); from
the doPost() method everything starts working!!!
By reading servlet spec, I figure out that doFilter get called before
Servlets' doPost()
Serlet 2.3 spec about filtering:
QUOTE
When the container receives an incoming request, it takes the first
filter
instance in the list and calls its doFilter method, passing in the
ServletRequest
and ServletResponse, and a reference to the FilterChain object it
will use.
END QUOTE
It still behaves a bit bifferent in IE (user can change encoding to
something else) and Firefox (encoding will be forced to one that set
by Filter)
--- code --
public void doPost( HttpServletRequest req, HttpServletResponse resp
)
throws IOException, ServletException
{
StringBuffer out;
// doing something and out HTML output in out ( StringBuffer)
.....
resp.setContentType("text/html"); // <=== do we need this line??
PrintWriter pw = resp.getWriter();
pw.println(out.toString());
}
--- end code ---
In all examples where HTML get generated by servlet I see this line:
resp.setContentType("text/html");
In my case Filter sets Encoding.
Can anybody confirm that resp.setContentType("text/html"); is not
nessesary
Thanks!
Mark.
