    Default Using getOutputStream() while getWriter() is open


    I've faced a problem with passing JSP parameter for PHP one using php-java bridge.

    The point is, I have to implement some function which will used to read the input into out put stream inside filter. That's why, caused some kind of IllegalStateException conflict.

    The code is,

    Java Code:
     HttpServletRequest httpRequest = (HttpServletRequest)request;
            HttpServletResponse httpResponse = (HttpServletResponse)response;
            RemoteHttpServletContextFactory ctx = 
                new RemoteHttpServletContextFactory(null, null, httpRequest, 
                                                    httpRequest, httpResponse);
            if (response instanceof HttpServletResponse) {
                System.out.println(" Enter CompressionServletResponseWrapper ");
                CompressionServletResponseWrapper wrappedResponse = 
                    new CompressionServletResponseWrapper((HttpServletResponse)response);
                wrappedResponse.setHeader("X_JAVABRIDGE_CONTEXT", ctx.getId());        
                wrappedResponse.setHeader("Pragma", "no-cache");
                wrappedResponse.setHeader("Cache-Control", "no-cache");
                try {
                    HttpSession session = httpRequest.getSession();
                    session.setAttribute("par1", "a");
                    session.setAttribute("par2", "b");
                                       wrappedResponse.getOutputStream()); //httpResponse
                    chain.doFilter(request, wrappedResponse);
                } catch (Exception ex) {
                } finally {
    Take in consideration that, the whole application use getWriter() while as mentioned before I have to used getOutputStream for response object.

    So, how could we handle this?

    Default Re: Using getOutputStream() while getWriter() is open

    None of that shows where you are using the streams.
    None of that shows us your error.
    Do you have an exception?
    If so then post it in full here, and highlight the line in your code where it is thrown.
    Also, do not ignore exceptions like that, at least printStackTrace().
    Please do not ask for code as refusal often offends.
