Cannot Set Header. Response Already Committed Was 6.1

Some apps have huge stacks of these, that can be over-eager to write headers. Looking at the code of ResourceHandlerImpl.handleResourceRequest(FacesContext context) I found the following snippet: try { InputStream in = resource.getInputStream(); OutputStream out = httpServletResponse.getOutputStream(); //byte[] buffer = new byte[_BUFFER_SIZE]; byte[] buffer = new Response already committed (jsf, primefaces)0faces - Application was not properly initialized at startup, could not find Factory: javax.faces.context.FacesContextFactory0primefaces fileupload not working with prettyfaces when use dynamic resource path to view id0Primefaces You need to rearrange the code logic so that it only sets the headers before the response is committed.

I've shown how this might be done by using introspection; but you can use ServletResponseWrapper and custom wrapper classes for the stream/writer if you prefer. I did some research and understood that Servlet is trying to send more data to the output stream, but the stream is already been committed. Fixed on: Websphere 7.0.0.21 + MySQL 5.

Funny though that it sets that param to false by default. 2. sendRedirectWithStatusCode(WebAppDispatcherContext.java:554) at com.ibm.ws.webcontainer.webapp.WebAppDispatcherContext.
