I have an utf-8 html form that searches in the database, and produces

I have 2 conversion problems :

response.setContentType("text/html;charset=utf-8") may be enough. It
will set the response writer/output stream conversion to utf-8.
How do you convert a string to utf8 ?
utf8bytes = name.getBytes("UTF8") gives you the UTF-8 output. If you pass that
directly to response.getOutputStream() that should be it. Don't try to convert it back
to a String once you have done the UTF-8 encoding. If your view is dealing with strings
or characters instead of bytes, let the view take care of the UTF-8 encoding. If your
view is JSP there are page directives for this. If your view relies or
response.getWriter() setting the desired charset in the content type should be enough.
If your view relies on response.getOutputStream() you need to take care of it yourself,
buy you also will write bytes to the output, not characters.
in the form I receive a string wich is encoded in utf8 by the browser,
but it is not recognized as utf8 by the server.
You may want to specify what character encoding your resin environment
expects <http://caucho.com/resin/doc/env-tags.xtp#character-encoding> .
Browsers typically return the form data encoded by whatever character
set the html document holding the form had, so if you present your form
in UFT-8 you can be reasonably sure you get utf-8 data back in the
submission. Just make sure you indeed have UTF-8 data in the form, with
a GET request the £ (GBP) character should show up as %C2%A9.
I cannot convert it to utf8 for mysql.
Let the mysql JDBC driver get the String, it will deal with any UTF-8
encoding internally by itself. Don't try to force it.
