[Mike Hanafey (JIRA)]

    [ http://jira.jboss.com/jira/browse/RF-2914?page=comments#action_12417620 ] 
            
Mike Hanafey commented on RF-2914:
----------------------------------

Tracing what leads up to the logged message reveals the following (in order of execution):


org.ajax4jsf.webapp.BaseFilter:
	protected void processUploadsAndHandleRequest(HttpServletRequest request, HttpServletResponse response,
		FilterChain chain) throws IOException, ServletException {
	    HttpServletRequest httpRequest = (HttpServletRequest) request;
	    String uid = httpRequest.getParameter(UPLOAD_FILES_ID);


In Glassfish, getParameter calls the following:

org.apache.coyote.tomcat5.CoyoteRequest
    protected void parseRequestParameters() {

        /* SJSAS 4936855
        requestParametersParsed = true;
        */

        Parameters parameters = coyoteRequest.getParameters();

        // getCharacterEncoding() may have been overridden to search for
        // hidden form field containing request encoding
        String enc = getCharacterEncoding();
        // START SJSAS 4936855
        // Delay updating requestParametersParsed to TRUE until
        // after getCharacterEncoding() has been called, because
        // getCharacterEncoding() may cause setCharacterEncoding() to be
        // called, and the latter will ignore the specified encoding if
        // requestParametersParsed is TRUE
        requestParametersParsed = true;

During the restore view phase, when initView(FacesContext ) is called the following is called (in the same CoyoteRequest class), and because "requestParametersParsed" was set true above, the warning is logged.

    public void setCharacterEncoding(String enc)
        throws UnsupportedEncodingException {

        // START SJSAS 4936855
        if (requestParametersParsed || usingReader) {
            String contextName =
                (getContext() != null ? getContext().getName() : "UNKNOWN");
            log.warn(sm.getString("coyoteRequest.setCharacterEncoding.ise",
                                  enc, contextName));
            return;
        }
        // END SJSAS 4936855

> Complex richfaces application works fine with 3.1.4 release. After update project libraries to 3.2.0 glassfish displays following message in error log:
> PWC4011: Unable to set request character encoding to UTF-8 from context /proc, because request parameters have already been read, or ServletRequest.getReader() has already been called
> and firefox displays empty page.
> If I switch back to 3.1.4 - application works fine.
> Any changes in web.xml (or any other web-app configuration file) I am missed during "upgrade" ?
> Thanks,
> Mareks
