File Downloading/Save problem
Hello All,
I have written a code to download a Text file from Server to Local Disk.But the problem
is that when i click a Button in the JSP page through which the downloading of file is
done,opens a Dialouge Box with the "Save To Disk " option selected.when i go for the
Save
option the Text Field shows me a Wrong Filename("downloadFile.htm")which is not
the
File i want Download.I want to Download "1003-3.txt"
Also when i go for the "OPEN" option and click on "OK" the Dialouge Box Opens again
with the "Save To Disk" option selected,when i click on "OK" the Text Field of the
Dialouge Box Shows the CORRECT Filename("1003-3.txt").when i click OK the File
gets DOWNLOADED but with "NO CONTENTS".
The snippet of code is .
public HttpServletResponse doDownloadFile(HttpServletRequest req,HttpServletResponse
res)
throws ServletException,IOException {
String fname = "1003-3.txt";
res.setContentType("application/binary");
res.setHeader("Content-Disposition","attachment; filename=\""+fname+"\";");
ServletOutputStream stream = null;
try {
stream = res.getOutputStream();
BufferedInputStream bif = new BufferedInputStream(new FileInputStream(fname));
int data;
while(( data = bif.read()) != -1) {
stream.write(data);
stream.flush();
}
bif.close();
stream.close();
return res;
} catch(Exception e) {
}
finally {
if (stream != null)
stream.close();
return res;
}
}
Can Anybody Help me out with the problemPlease it is URGENT!!

Re: File Downloading from server to local disk
Hello Vikramjit Singh,
Thank you very much for your co-operation.
I am experiencing a strange problem.The File which i want to Download
is
"1003-3.txt",but when i try to download this file the Dialouge box
window ask me for
two options "Open or Save to Disk " .If i go for "Open" ,the File
"Opens" Properly but
when i try to "Save To Disk" the File which is getting Downloaded
is
"downloadFile.htm".
The code is as follows.
try
{
File f= new File("c:/ssmtech/download/customers/1003-3.txt");
res.setContentType("text/plain");
res.setContentLength((int) f.length());
res.setHeader("Content-Disposition","attachment; filename=\"" + f+"\"");
FileInputStream fis = new FileInputStream(f);
ServletOutputStream os = res.getOutputStream();
int i;
while ((i = fis.read()) != -1)
{
os.write(i);
}
fis.close();
os.close();
return res;
}
catch(Exception e)

}
}

Retrieving Multiple values of single Parameter
Hello All, I have a JSP page with a list of Customers along with there respective Checkboxes. The values contained in the Checkboxes are CustomerId's of the respective Customers. After checking the Checkboxes i have a Link "Actions" which opens a new Page. I am trasfering the checked values(CustomerId's) to this new Page through the "URL". For Example, URL=CustomerId=1&CustomerId=2&CustomerId=3... and so on. So my problem is How do I catch Multiple Values of a single parameter to this new page.Also i need to Submit these values in the Backend. Sameer
Problem while displaying pages in Iframe
Hello friends, I have a Customermain.jsp page which is server generated. In this page there are four iframes."src" parameters referencing to four different pagesnamely : 1 MainInfo.jsp 2 Addresses.jsp 3 Contacts.jsp 4 MiscInfo.jsp These pages are also generated dynamically. After deploying on the j2ee server, the first time Customermain page displays the above pages correctly in their corresponding positions.But on refreshing the CustomerMain page or calling it again for another customer,it gives erratic result. For eg : It shows address page at Contactpage location or Contact page in another location or the same page in all four locations.
