How to download files in jsp code {through save dialog}

can you help me to download files in jsp code {through save dialog}
i use the following code but it saves the jsp page instead of the downloaded file but with the name of the wanted file to be downloaded
response.setHeader("Pragma", "public");
response.setHeader("Cache-Control", "no-cache");
*** download file
if((trans !=null)&&(trans.equals("download")) )
response.setContentType ("application/x-download");
response.setHeader ("Content-Disposition","attachment;filename=\""+fileName+"\"");
%>
<script>
window.location.href=<%=gallerypath+fileName%>';
</script>
<%
trans="";
//System.out.print("download : "+fileName );
//***************************************

Can you try below code, It should work...
<%
String myFileName = request.getParameter("fileName");
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment; filename=\"" + myFileName + "\"");
String root = "D:/";
InputStream in = null;
ServletOutputStream outs = response.getOutputStream();
try {
in = new BufferedInputStream
(new FileInputStream(root + myFileName));
int ch;
while ((ch = in.read()) != -1) {
outs.print((char) ch);
finally {
if (in != null) in.close(); // very important
outs.flush();
outs.close();
in.close();

How to download file in jsp

Hi guys,
I am a new member to this java community. I meet some problems in doing my project, hope you experts can help me.
I want to add a download button in my jsp code. When users click the button, a file will be downloaded to his local computer. The files are ASCII files with .asc as extension. My server is Apache 1.3.19 with tomcat 3.2.1 . What kind of code should I add to my jsp?
Anyone's quick response is greatly appreciated.

Thanks for your reply.
I have tried to use the hyper link in html. But since it's ASCII file with .asc extension, every time the link is clicked, the file is opened directly instead of offering save option. So maybe some special code is needed.
Many software web site provides download page. When user clicks the download button, the file will be transfered to user's computer. Does anyone knows how to do it?
Thanks.

Just drag the file from the Download folder to the folder of your choice in Finder. If you are using Safari you can designate a new default download destination in Safari>Preferences>General tab, 'Save Downloads to...'. Other browsers should have a similar option in their preferences.

Sun JSC2 - How to download files to client

Hi, imagine a document management site.
I want to have a list of files with links that users can click to download them.
Users can upload files (with handy File Upload component), and they get saved as byte streams to a file or database or whatever.
Now, I have a page with a list of files the user can download. The file name, a link to save the file, and a link to download the file.
File1.pdf . . . DOWNLOAD IT! . . . SAVE IT!
The DOWNLOAD IT! link tries to use mime stuff to get the browser to open the file.
The SAVE IT! link tells the browser to not process the file and always bring up the save as dialog. In both cases, I don't want the browser to open a new page.
Starting with a byte[], what's the best way to do this? I searched the web, and these forums, but couldn't come up with anything that gave me a place to start from inside JSC2.
Any ideas on where to start? Thanks in advance!
Mike

Hey Winston, here is what I came up with... Very similar, but a little different.
Java Server Faces File Download Tutorial by Michael Cole
Java Server Faces, abstracts much of the monotonous detail of web programming, letting application developers develop applications, instead of programming servers.
This tutorial explains how to dip just a little under the covers to serve files to a browser. The browser can then interpret this binary data using MIME types. Some common MIME types are �text/plain�, �text/html�, or �application/pdf� or �application/x-unknown�.
How the browser behaves when interacting with these MIME types is based on the client browser's configuration. Because this configuration is different for every browser, let's create two different behaviors:
* First Behavior: When a link is clicked, the browser downloads and �opens� the file, either displaying the file itself, or choosing an appropriate program: zip file program, pdf program, etc.
* Second Behavior: The browser always offers to save the file, no matter what.
At the most basic level, we want to cause this chain of events:
1. Cause browser to send a request to the server.
2. Have the server create a response that sends the file to the client.
For my purposes, the browser should not navigate to a new page for this behavior.
A mockup might look like this:
Files you can download:
Secrets of the Universe.txt
Open it!
Save it!
Perfect love and happiness.pdf
Open it!
Save it!
Make a million dollars now.swf
Open it!
Save it!
To accomplish this, we will execute this code on the server:
// Find the HttpServletResponse object for this request.
// With this object, we can create a response that sends the file.
FacesContext faces = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) faces.getExternalContext().getResponse();
// We can also get information about what the browser requested.
// This could tell us what data to send
HttpServletRequest request = (HttpServletRequest) faces.getExternalContext().getRequest();
// Your data can be stored in a database, generated at runtime, or whatever you choose.
// We getSomeData() from an arbitrary location. This depends on your application.
byte[] data = getSomeData(request);
// In the response, we will specify a file name to present to the user.
String filename = "myFile.txt";
// Now we have the data to send, and the response object to send it with.
// Next we give the browser some hints on what to do with the file.
// Note that different browsers will behave differently and you have no control over this.
// We'll use different mime types to implement the different "Open" and "Save" behaviors.
// "application/x-unknown" will be the MIME type used for the "Save" behavior.
response.setContentType(mimeType);
// We tell the browser how much data to expect.
response.setContentLength(data.length);
// Cross-browser hack for Firefox 1.0.7 and IE 6 compatibility.
// IE 6 ignores the MIME type and decides based on the "attachment" or "inline"
if (mimeType.equals("application/x-unknown")) {
// Show the "Save As..." dialog
response.setHeader( "Content-disposition", "attachment; filename=\"" + filename + "\"");
} else {
// attempt to "open" the file
response.setHeader( "Content-disposition", "inline; filename=\"" + filename + "\"");
// Now we start sending data with the response object.
// You might consider using a buffer if your data comes from a large file
// or a database.
try {
ServletOutputStream out;
out = response.getOutputStream();
out.write(data);
} catch (IOException e) {
e.printStackTrace();
// Lastly and very importantly, we tell Java Server Faces that
// the request has been handled and not to process it any more.
faces.responseComplete();
Now all we have to do is put this code somewhere.
Step 1: Build the page UI.
* Create a new page in Java Studio Creator. Let's call it �download.jsp�
* Make it the start page (right-click)
* Add a hyperlink component and call it �Open!�
* If you like, add a static text that describes your file.
Step 2: Tell Java Server Faces what to do when the hyperlink is clicked.
* Doubleclick the hyperlink and add this code to it's action:
public String hyperlink1_action() {
// TODO: Replace with your code
DownloadBean d = new DownloadBean();
d.sendFile("text/plain");
return null;
* Compile the download.java and get a �cannot find symbol for class DownloadBean�. Now we have a place to put our code to send the file!
Step 3: Build the DownloadBean that will serve the file.
* Go to your "Source Packages" folder and create a new Java class in the project's package. Call this class �DownloadBean�.
* Copy this code into the class:
public void sendFile(String mimeType) {
FacesContext faces = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) faces.getExternalContext().getResponse();
HttpServletRequest request = (HttpServletRequest) faces.getExternalContext().getRequest();
byte[] data = getSomeData(request);
String filename = "myFile.txt";
// Note that different browsers will behave differently and you have no control over this.
// We'll use different mime types to implement the different "Open" and "Save" behaviors.
// "application/x-unknown" will be the MIME type used for the "Save" behavior.
response.setContentType(mimeType);
response.setContentLength(data.length);
// Cross-browser hack for Firefox 1.0.7 and IE 6 compatibility.
// IE 6 ignores the MIME type and decides based on the "attachment" or "inline"
if (mimeType.equals("application/x-unknown")) {
// Show the "Save As..." dialog
response.setHeader( "Content-disposition", "attachment; filename=\"" + filename + "\"");
} else {
// attempt to "open" the file
response.setHeader( "Content-disposition", "inline; filename=\"" + filename + "\"");
// Now we start sending data with the response object.
try {
ServletOutputStream out;
out = response.getOutputStream();
out.write(data);
} catch (IOException e) {
e.printStackTrace();
faces.responseComplete();
* Hit Ctrl-Shift-F to make the code pretty.
* Try and compile DownloadBean.java. Build->Compile
* As expected, you will get a variety of �cannot find symbol� errors.
* Hit Ctrl-Alt-F to clean these up, by automatically adding the proper imports.
* Try and compile again and you will get a �cannot find symbol� error for the getSomeData() function. That's ok cause we didn't write it yet.
* Copy this code into the DownloadBean class:
public byte[] getSomeData(Object o) {
// ignore the HttpServletRequest object and return some data.
return "Hello World!".getBytes();
* Compile the file one last time to get a clean compile.
Why didn't we put this code directly in the hyperlink1_action() function? Because we are separating the �model� from the "view" and "controller". DownloadBean can be reused in any page of your application now.
Step 4: Test
1. Run the project and open the page in the Firefox web browser.
2. Click the �Open It!� hyperlink
3. A text file should appear in Firefox that says �Hello World!�
Great! We sent the file, Firefox interpreted the �text/plain� MIME type, and presented the text as a browser page. This covers our �Open It!� functionality.
To serve other kinds of files, pass a different MIME type in the sendFile() function.
For a list of MIME types, check out http://www.webmaster-toolkit.com/mime-types.shtml
Step 5: Save It! Functionality.
What if we always want the file to be saved, no matter what foolishness the browser wants to do with the file?
* Go back to the Design of download.jsp.
* Add another hyperlink to the page, label it �Save It!�
* Double click the hyperlink and JSC2 will take you to its action function.
* Add this code to the function
public String hyperlink2_action() {
// TODO: Replace with your code
DownloadBean d = new DownloadBean();
d.sendFile("application/x-unknown");
return null;
Notice the difference in the MIME type? We changed �text/plain� to �application/x-unknown�. Notice also in the sendFile() function the cross-browser hack to get IE 6.0 to save or open the file.
* Run the project one last time.
* Test with Firefox
* Test with Internet Explorer
Done!

How to download file from server to client's local ??

How to download a file from the server to the client's local machine in a particular folder without users intervention ie. 'Save As" prompt of the browser should be avoided and if the client clicks on "Download" button, the file should get automaticaly downloaded to say, "c:/reports/' on his/her local machine. This is for Java based web appliaction.

Download file via jsp

dear all,
to download a *.txt-file via jsp i use following code:
java.io.File file = new java.io.File("C:\\FileName.txt");
response.setHeader("Content-Disposition", "attachment;filename=\""+file.getName()+"\";");
response.setContentType("APPLICATION/OCTET-STREAM");
response.setContentLength((int) file.length());
if(file.isFile()){
     java.io.FileInputStream fis = new java.io.FileInputStream(file);
     java.io.BufferedOutputStream bos = new java.io.BufferedOutputStream(response.getOutputStream());
     byte b[] = new byte[(int)file.length()];
     int read = 0;
     while((read = fis.read(b)) != -1){
          bos.write(b,0,read);
     bos.flush();
     fis.close();
     bos.close();
} the problem is:
the file will be displayed in the browser IE6 (inline), but i want to open a save-dialog!
any ideas?!
thanks for help. andy

up to now i tried another browser (mozilla firebird) and several settings about the contenttype like:
- application/x-download
- application/x-msdownload
- application/x-octet-stream
- application/octet-stream
- application/download
... and the file-name like:
*.zip
*.txt
*.exe
but the browser shows the content of the file always inline (even *.zip and *.exe files!!).
anyway, thank you for help.

How to download radio documentaries to ipod through computer.

how do i download radio documentaries to ipod through computer. when i look at the doc site it has i tunes next to each documentary.thank you.

I have to admit, both RTÉ and iTunes now make this a long-drawn-out procedure. However...
evvyseamus wrote:
the site is www.rte radio1/doconone/. hope this helps
If you mean http://www.rte.ie/radio1/doconone/ - then presumably you clicked on this:
which took you to this page: http://www.rte.ie/radio1/podcast/podcast_documentaryonone.xml .
On that page, at the very bottom, is a section titled How to get this Podcast. Copy the Podcast URL (starting http://) and then in your iTunes, use CTRL+B to display the top menu bar. On that, click on File/Subscribe to Podcast and paste the URL into the box. That should subscribe you to their Podcast, despite being a longer process than it needs to be.
If you are referring to another site, the procedure is still (basically) the same: find the Podcast's URL and paste it into the iTunes Subscribe to Podcast box. An efficient site will actually open iTunes to the "are you sure you want to subscribe" page. Perhaps RTÉ have a bit to learn.

How to execute again the JSP codes

Dear Experts,
I am having trouble to execute again the JSP codes in my abc.jsp page. The sequence of the codes are:
[ JSP codes ]
[ HTML codes]
My JSP file is selecting from DB2 and display the results on the same page. The selecting is depending to the selection in the combo box and included the selection into the SQL statement.
The problem is when I change the selection at the combo box, how can I refresh the page and fill in with the new results from database by selecting with the new keyword.

You will have to do an onChange handler for the select box, that simply submits the form, and the action would be the current page.

How to compile and deploy JSP code from Unix server command line?

I am new to JSP technology. We are thinking to modify some of JSP code to meet our need. But I am not sure what I should do after I change JSP code. How can I compile the changed code? How to deploy? How to publish on the web?

All files are regenerated if changed.
That goes for the .java and the .class files that are created. The jsp server checks to see if the current version is the latest. If it is, nothing gets changed or recompiled. If things are different, programs are recompiled.
Youll notice that if you have a new jsp it always takes longer the first time. Or even when you change a jsp, the first time takes the longest for the page to come up in a browser. This is because of recompiling.
Does this make any sense?

ADF: how to download files?

good day,
does anyone know what the best way is to download a file to the client side using ADF? is this a trivial thing to do? i can find docs online on how to upload files using ADF but nothing for downloading files using ADF.
initially, my thought was to use the FacesContext ResponseStream; but quickly realized that facesContext.getResponseStream returns a null with in my backend bean. so, i decided to bypass ADF and use HttpServletResponse's ServletOutputStream and simply write to this object. this works fine but ran into another problem, this comletely bypasses the ADF framework. after downloading the file ADF does not know what state it is in (i.e. my pages do not get updated). nothing gets updated via ADF.
a second approach was to to kick off writing the Servlet OutputStream in a separate thread and have the backend bean return first. well... ran into another problem: java.lang.IllegalStateException: getOutputStream() has already been called!. obviously, i do not understand how the response mechanism works for servlets :-( it appears that per request the ouputstream can be only written to/flushed once.
so if anyone has a way to correctly download a file using ADF please share.
thank you

Lius,
thank you for the link. i read through it.
for a existing file on the server a redirect works. but what if i do not have a physical file on the server and i simply want to write it from memory to the client side. i would like to write an outputstream object from the server directly to the user's browser.
from the backend bean i do the following:
ServletOutputStream out = response.getOutputStream();
ByteArrayOutputStream outputStream = getOutputStream();
// Reading the bytes through buffered input stream and writing the
// presentation to the servlet output stream in the form of bytes
// using
// buffered output stream\
while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff, 0, bytesRead);
// Flushing the buffers of Http Response. this is bad for ADF.
response.flushBuffer();
and once i flush the buffer here it returns to the client and the user can than download the file but it completely bypasses the ADF framework and i am unable to make any ADF callbacks (i.e. send messages or use adf progress bar) :-(
is there a way to download a file to an ouputstream without having it on the server side as a file.
thanks for you help,
joon
