Documents from UCM not opening in some browsers

Question

Hi ,
I am using the RIDC GET_FILE service to display the pdf in the WebCenter portal page. When the method is called the pdf document opens in Chrome browser in some machines but not in Firefox or other browsers. The file is returned as "application/octet-stream" and hence does not open as a pdf document.
Following is the java code written to fetch the files
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.io.PrintWriter;
import javax.servlet.*;
import javax.servlet.http.*;

import oracle.javatools.resourcebundle.BundleFactory;
import oracle.security.xmlsec.samlp.ResponseType;

import oracle.stellent.ridc.protocol.ServiceResponse;
import utils.system;
    public class getFile extends HttpServlet {
        private static final String CONTENT_TYPE = "text/html; charset=UTF-8";
        private static final long serialVersionUID = 1L;
        public void init(ServletConfig config) throws ServletException {
            super.init(config);
        String cid ;
    public  void doGet( HttpServletRequest request,
                        HttpServletResponse response) throws  ServletException ,IOException {
                   try {
                       cid = request.getParameter("cid");
                   } catch (Exception e) {
                       e.printStackTrace();
        try{
            IdcClientManager manager = new IdcClientManager();
            IdcClient idcClient = manager.createClient("idc://oa8054.us.oracle.com:7444");
            IdcContext userContext = new IdcContext("SADMIN", "SADMIN1");
                    System.out.println("got idc client");
                // populate the binder with the parameters
                    DataBinder dataBinder = idcClient.createBinder();
                    dataBinder.putLocal("IdcService", "GET_FILE");
                    dataBinder.putLocal("dDocName",cid);
                    dataBinder.putLocal("RevisionSelectionMethod","Latest");
                    dataBinder.putLocal("Rendition","Web");  
                 dataBinder.putLocal("allowInterrupt","1");
                    ServiceResponse response1 = idcClient.sendRequest (userContext, dataBinder);
                response1 = idcClient.sendRequest (userContext, dataBinder);
                     InputStream content = response1.getResponseStream() ;  
                    BufferedOutputStream  output = new BufferedOutputStream(response.getOutputStream(), 1024);             
                    byte[] buffer = new byte[1024]; 
                    int length;
                    while ((length = content.read(buffer)) > 0){ 
                    output.write(buffer, 0, length); 
            content.close(); 
            output.flush();
                    output.close();
                catch (IdcClientException e) {
                             e.printStackTrace();
And the call to the servlet is  made on click of a link.
Why doesn't the documents() open in some browsers while it does in some.Similarly i want to open docx and rtf files from UCM also using the same code without downloading.
Please help.
Thanks

Hi.
Try following sample code:
Include cmfn tag library in your page
xmlns:cmfn="http://xmlns.oracle.com/webcenter/content/functions"
Use next EL Expression to get a Node url's (are the same methods as a Node in CP):
#{cmfn:getNodeById(yourdDocName).url.downloadUrl
#{cmfn:getNodeById(yourdDocName).url.renderUrl
Sample:
<af:goLink targetFrame="_blank" destination="#{cmfn:getNodeById('UCM676546').url.downloadUrl}"/>
You'll need connection to UCM configured in your WebCenter Portal Application because it will ask for the current IDC connection configured.
Regards.
