Download a file using jsp
Hi All,
I have a jsp with which I download the .Excel file from server, I am using i.e 6 my problem is when I click on download link it opens the file in same browser, How I can force it to open in excel not in a browser. It works fine fire fox.
Please help.
Thanks
You need to set the correct response headers, these work fine for me:
//control cache, these make the difference
response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
response.setHeader("Pragma", "Public");
//these are xls specific
response.setHeader("Content-Disposition", "attachment; filename=action.xls");
response.setHeader("Content-Type", "application/vnd.ms-excel");Does this help you? Otherwise let us know which framework you're using so we can provide you with more details.

Hi All,
I am working on a JAVA/JSP application. JSP page passes the user inputs to JAVA page (using POST method) which queries to the database and generate an Excel file and returns the link for that file. I am displaying that link in JSP page ("Your file is successfully saved. Click here to download or view your file).
Now what I want is when the user clicks on the link, open/save dialog will appear which give flexibility to the user to download or view the file in same JSP page. The problem is I don�t want to post again the data or dont want to open a child window. How to set the content type without posting it (I don�t know much about this). Is there any way to do this?
Any help is highly appreciated. Thanx in advance
Cheers

How do I download PDF files using Safari. All I get is a black screen.
How do I download PDF files using Safari. All I get is a black screen.
Back up all data.
Quit Safari. In the Finder, select Go ▹ Go to Folder... from the menu bar, or press the key combination shift-command-G. Copy the line of text below into the box that opens, and press return:
/Library/Internet Plug-ins
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then launch Safari and test.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again. -
I can not download any files using Safari ? when I choose to download application file the URL include the file name and stop responding. Any help??
Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. The Guest login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2. -
Download a file using GetRight
How is it possibe to download a file using a downloader like getright? I am trying to get
oracle-xe-universal_10.2.0.1-1.0_i386.deb
but if I transfer it to Getright it fails to login, although I ve done it using the browser.Well, normally it does. It's only at oracle.com that it doesn't work, and I wonder why. I tried putting directly the uid and the passwd but it didn't work either.

How to download a file using servlet
I have a problem about downloading a file using a servlet.
Anybody can help me?
ThanksI am assuming that you want to write a servlet that, when invoked by a user (for instance, through a URL link), will download a file using the "save as" dialog (on Windows, for example) in the user's browser.
In such a case, all you need to do is get the OutputStream from the response object, set the proper MIME type header, and write the file. Here is an (untested, not even compiled) skeleton.
public class MyServlet extends HttpServlet {
protected void doGet (HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
ServletOutputStream out = resp.getOutputStream ();
resp.setContentType ("application/x-foobar");
while (/* whatever */) {
In this loop, you generate your "file's" data.
You can compute it on the fly, pull it from a database,
read it from a "real" file, or any other means you can dream up.
The sample line below just writes some of the data (for example,
a byte array) to the user's browser via the output stream out.
out.write (data);
out.flush ();
Go to http://java.sun.com/j2ee/sdk_1.3/techdocs/api/index.html
for the JavaDoc on the classes used.

Invalid File after Downloading from Database using JSP/JDev 10.1.2
Hi, i got a problem when i download a file from my blobColumn in database.
Well, actually i got no problem in reading the file out of database, but when i download this file, there are 3 more bytes then in the original one in Database...
Here's my java-code in the jsp-page i used as "save as" field:
Hashtable ht = Dokument.createDOK(request);
String dateiname = (String)ht.get("Dateiname");
byte[] fileBytes = (byte[])ht.get("Dokument");
ByteArrayOutputStream ba = new ByteArrayOutputStream();
ba.write(fileBytes);
// RESPONSE
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment; filename=\"" + dateiname + "\"");
// DOWNLOAD
OutputStream outs = response.getOutputStream();
ba.writeTo(outs);
outs.flush();
outs.close();
}catch(Exception ex){
ex.printStackTrace();
for testing i used a simple text file with 28bytes:
begin----
Test Zeile 1.
Test Zeile 2.
end-------
after downloading this file it looks like:
begin----
Test Zeile 1.
Test Zeile 2.
end-------
There are 3 bytes 0A(hex) at the beginning...
I dont know why.
after closing "outs" i made system.out for checking the amount of bytes in "fileBytes"-Array, and it was correct, just the 28 bytes like in the file from the Database.
But i actually dont get, why there are 3 more bytes at the beginning after downloading it.
The main problem is, some other files like word or excel documents cannt be opened, because of this 3 bytes at the beginning, and they seem to be invalid.
Would be glad if someone can help me, got really stuck and have no idea any more.
Thanks
SebastianDont someone has a solution, or got a similar problem ?
Thought about it could be a bug in the basic java classes of JDev 10.1.2
but i dont really know...
Have no idea left.
