Hi Ramadeep,
Thanks for your quick help.I am able to do the same with dDocName.but I m facing problem while setting contentType means MIME type to file. I am usig the below code for the same but contentType is taking null value.
please take a lookinto code and give mw some solution.
is this code is file or can I optimized.
    public void downloadFileUCM(FacesContext facesContext,
                                OutputStream outputStream) {
        IdcClientManager manager = new IdcClientManager();
        IdcClient idcClient;
        try {
            idcClient = manager.createClient(IDC_URL);
            IdcContext userContext = new IdcContext(USER);
            DataBinder dataBinder = idcClient.createBinder();
            dataBinder.putLocal("IdcService", "GET_FILE");
             dataBinder.putLocal("dDocName", ucmResourceId);
            dataBinder.putLocal("RevisionSelectionMethod", "LatestReleased");
            ServiceResponse responseString =
                idcClient.sendRequest(userContext, dataBinder);
           setContentType(responseString.getHeader("Content-Type"));
            String contentType=responseString.getHeader("Content-Type");
            System.out.println("contentType:"+contentType);
             InputStream inputStream = responseString.getResponseStream();
            byte[] buf = new byte[1024 * 256];
            long i = 0;
            int len;
            System.out.println("Downloading File from UCM Server");
            while (true) {
                i++;
                len = inputStream.read(buf);
                if (len == -1) {
                    break;
                outputStream.write(buf, 0, len);
            outputStream.flush();
            inputStream.close();
            outputStream.close();
            facesContext.responseComplete();
        } catch (IdcClientException ice) {
            System.out.println("IDC Client Exception occured. Exception message: " +
                               ice.getMessage());
        } catch (IOException ioe) {
            System.out.println("IO Exception occurred. Unable to retrieve file. Message: " +
                               ioe.getMessage());
        } catch (Exception ex) {
            System.out.println("Exception message: " + ex.getMessage());
    }Regards
