> Deploying wicket-examples to Glassfish produces tens of warnings on each
> request in the server log with the following text:
> WARNING: PWC4011: Unable to set request character encoding to UTF-8 from
> context /wicket-examples, because request parameters have already been read,
> or ServletRequest.getReader() has already been called
> According to Glassfish faq
> http://wikis.sun.com/display/glassfish/FaqWebAppUnableToSetRequestCharEncoding:
> """
> This warning message means that the web container is complaining about the
> fact that the web application deployed at /your_webapp is trying to set the
> request encoding too late in the request's lifecycle, when it is impossible
> for the container to honor it.
> See the javadocs of javax.servlet.ServletRequest.setCharacterEncoding():
> This method must be called prior to reading request parameters or reading
> input using getReader(). Otherwise, it has no effect.
> The container issues a warning to let you know that a call to
> ServletRequest.setCharacterEncoding() by your_webapp has no effect and is
> being ignored, because one of the above conditions is met.
> To avoid this warning, your_webapp should move its invocation of
> ServletRequest.setCharacterEncoding() to an earlier stage, before it acquires
> any input reader from the request, or before it reads any request parameters.
> In case your_webapp is not responsible for this warning, one if its
> dependencies might be, in which case that library needs to be fixed.
