Hello everybody,
I have to send a file to the response for the browser
to show a save/open file dialog box to the user, so
he/she can download it and save in in his/her local
file system. As expected the file is stored in a
specific directory in the file system of the server.
What I did was to call this method within a
commandLink component:
public String downloadDB(){
FacesContext context =
FacesContext.getCurrentInstance();
HttpServletRequest request = (
HttpServletRequest )
context.getExternalContext().getRequest( );
HttpServletResponse response =
( HttpServletResponse )
context.getExternalContext().getResponse();
String filePath = null;
int read = 0;
byte[] bytes = new byte[1024];
filePath = getMyDBPath();
response.setContentType("application/pdf");
FileInputStream fis = null;
OutputStream os = null;
try {
fis = new FileInputStream(new
File(filePath));
os = response.getOutputStream();
while((read = fis.read(bytes)) != -1){
os.write(bytes,0,read);
}
os.flush();
os.close();
}
catch ( FileNotFoundException e1 ) {
logger.error(e1);
logger.info(e1.getMessage());
request.setAttribute("errors", "File Not
Found.");
}
catch ( IOException ioe ) {
logger.error(ioe);
logger.info(ioe.getMessage());
request.setAttribute("errors", "Error reading
file.");
}
return "";
}
After the user clicks on the commandLink, the page I'm
working on, gets refreshed and at the top of it
appears the text of the file I tried to download. This
is not the expected behaviour, what should I do?
thanks a lot,
Johnny
