Download file from URL using ADF (urgent help required)

Question

We have the following requirement:
On clicking a button we need to download the file present at a particular location(we have the URL).
I have written the following in .jspx file :
<af:commandButton  id="btn1" >
                    <af:fileDownloadActionListener contentType="text/plain; charset=utf-8" method="#{bean.getFile}"/>
</af:commandButton>
The corresponding method in bean is :
public void getFile(FacesContext facesContext, OutputStream outputStream) {
HttpServletResponse response = null;
ServletOutputStream ouputStream = null;
currUrl = getFileURL("ID", 281);
response =
(HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
try {
ouputStream = response.getOutputStream();
ouputStream.write(this.getFileBytes(), 0,this.getFileBytes().length);
ouputStream.flush();
ouputStream.close();
} catch (IOException ioe) {
System.out.println("IO Exception");
public byte[] getFileBytes() {
URLConnection urlConn = null;
InputStream iStream = null;
URL url;
byte[] buf;
int byteRead;
try {
url= new URL("http://hjhj:34104/test.pdf");
urlConn = url.openConnection();
iStream = urlConn.getInputStream();
buf = new byte[5000000];
byteRead = iStream.read(buf);
if (byteRead > 0) {
System.out.println("Downloaded Successfully.");
return buf;
} catch (FileNotFoundException fnfe) {
System.out.println("File not found Exception");
fnfe.printStackTrace();
} catch (Exception e) {
System.out.println("Exception:" + e.getMessage());
e.printStackTrace();
} finally {
try {
iStream.close();
} catch (IOException e) {
System.out.println("IO Exception");
e.printStackTrace();
System.out.println("File");
return null;
The file is opening in same window but in some encrypted format. My requirement is to :
1. Have a pop (as in Mozilla or IE) which asks if I want to save the file or open.
2. Depending on that the file should be opened in pdf format and not in browser same window neither in browser tab.

Jdev version : 11.1.2.1.0
in .jspx file : we have a button. On clicking the button file from URL should be downloaded. I have used fileDownloadActionListener in commandButton. Corresponding code :
<af:commandButton  id="btn1" >
                    <af:fileDownloadActionListener contentType="text/plain; charset=utf-8" method="#{bean.getFile}"/>
</af:commandButton>
in bean class : the method corresponding to fileDownloadActionListener is :
public void getFile(FacesContext facesContext, OutputStream outputStream) {
     HttpServletResponse response = null;
     ServletOutputStream ouputStream = null;
     response =(HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
     try {
          ouputStream = response.getOutputStream();
          ouputStream.write(this.getFileBytes(), 0,this.getFileBytes().length);
          ouputStream.flush();
          ouputStream.close();
          } catch (IOException ioe) {
               System.out.println("IO Exception");
public byte[] getFileBytes() {
     URLConnection urlConn = null;
     InputStream iStream = null;
     URL url;
     byte[] buf;
     int byteRead;
     try {
          url= new URL("http://hjhj:34104/test");
          urlConn = url.openConnection();
          iStream = urlConn.getInputStream();
          buf = new byte[5000000];
          byteRead = iStream.read(buf);
          if (byteRead > 0) {
               System.out.println("Downloaded Successfully.");
          return buf;   
    } catch (FileNotFoundException fnfe) {
          System.out.println("File not found Exception");
     } catch (Exception e) {
          System.out.println("IO Exception");
The URL given in the code is for a file which can be a PDF file or an EXCEL file.
My requirement is when i click the button:
1. A pop should come (as in Mozilla or IE) which asks if I want to save the file or open.
2. if i click on save file should save in a particular location.
3. if i click on open it should open as PDF/EXCEL format and NOT in browser.
