File download with JSP

I have found some code within this forum that I have been attempting to use to allow customers to download text files to their PC's. The code below is what I have come up with from my understandings on exactly how it should work, but it just will not work ...
Am I correct in assuming that the file that I want to make available for download is specified within the File f = new File(path+filename); section???
I have made the path variable refer directly to the file system (/disk2/invoice/) as well as via http (http://domain.com/invoice/) but it will not work !!!
It returns the save/open dialog but as soon as I select an option it returns a windows error prompt as follows:
Internet Explorer cannot download ...p?filename=123414_76453_437 from www.domain.com.
Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.
Can someone please tell me, where am I supposed to reference the file to be downloaded and how am I to reference it ???
<%
// get the file name from the calling page
String filename = request.getParameter("filename");
//get the file path to the file I want to make available via download
String path = getServletContext().getInitParameter("invoicePath");
response.setContentType("text/plain");
response.setHeader("Content-Disposition","attachment; filename=\""+filename+"\";");
int iRead;
FileInputStream stream = null;
try {
 File f = new File(path+filename);
 stream = new FileInputStream(f);
 while ((iRead = stream.read()) != -1) {
 out.write(iRead);
 out.flush();
finally {
 if (stream != null) {
 stream.close();
%>
<%@ page import="java.io.*,javax.servlet.*,java.util.* " contentType="text/html" %>
<html>
finally we have success ...
</html>

For those of you who are still having issues that have been unresolved trying to download a file from a webserver to a client, I have finally figured out how to do so ...
The following code now works for me on Solaris running Tomcat 3.1 and on W2K running JRun 3.2 ...
Issue 1: I specified a contentType=text/html in the page specification ... This must be removed ...
<%@ page ... contentType=text/html%>
Issue 2: The new File() reference must be a direct path to the file on the operating system. This does not work if it is referenced with a http path.
Other than that, I have included the code that I use to make files available for download on our webserver.
<%@ page import="java.io.*,javax.servlet.*,java.util.* "%>
<%
// get the file name
String filename = request.getParameter("filename");
//get the file path
String path = getServletContext().getInitParameter("invoicePath");
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment; filename=\""+filename+"\";");
int iRead;
FileInputStream stream = null;
try {
 File f = new File("/disk2/wwwhome/psmerged/invoice/" + filename);
 stream = new FileInputStream(f);
 while ((iRead = stream.read()) != -1) {
 out.write(iRead);
 out.flush();
finally {
 if (stream != null) {
 stream.close();
%>

PDF files download as JSP

I just upgraded to Leopard 10.5.6 this weekend from Tiger 10.4.11 then upgraded to 10.5.8. All went well except for a small glitch in Mail which I got fixed with the help of this forum. My newest problem is this morning I went online to my bank to download our monthly statement which always is in PDF format. The file downloaded fine, except the file title says it's a PDF, but the extension is .jsp. I contacted the bank and they have changed nothing so I am wondering is there a setting I need to change somewhere that would affect the download? At present I haven't found an application that will open .jsp files, but first I want to get them back to PDF format. Any suggestions will be appreciated.

Have you tried renaming the file so that its extension is ".pdf"? I believe I regularly download PDF files that have "jsp" in the file name, but renaming them corrects the problem.

How to make a jar file downloadable with IE

hello,
I just bought a website:
http://www.frozenfountain.net/
and I put a jar file on it called Logo.jar
Using Mozilla, the jar file downloads as expected, but with Internet Explorer, it tries to download it as .zip file.
How do I get it to download as a .jar file with IE?
thanks

Just post a link to the Jar. Mozilla will download
it as a jar. Windows will download it as a zip.
Only one link. No problem, really. ;-)There is a problem. People who arent as good with computers as you are won't know how to run the jar file after downloading with IE.
At school, I told someone to download the file, which they did with IE. It downloaded to desktop as a zip. They extracted and were left with a bunch of .class files.
On a sidenote, how do you draw text with a gradient?

Pdf files download with .file extension thus wont open as a pdf

Hi , when I try to download a pdf document with Firefox, the file downloads but add a .file extension thus wont open as a pdf.
I do not know if this is relevant but if you try to get the file to open with adobe viewer by telling the pc to open this type of file always with adobe viewer, nothing happens the tick box is greyed out, however if I double click the adobe viewer icon it will quite happily open the downloaded file as a pdf

The next time you download, STOP, and double check the full name of the file.
Firefox would not change the file name. But an add-on could.

Problem with file download through JSP under WLS6.1 SP3

Hello,
We're in the process of trying to migrate from WLS 6.1 SP1 to SP3, and we're encountering
some difficulties with this migration.
I'm attaching a very simple JSP here - it's a snippet from a larger more dynamic
JSP, that I managed to narrow down to a pretty simple case which still doesn't
work.
This JSP opens a file residing at "c:\\BDELog.txt" (it's hardcoded - so change
it to any textual local file on your machine in order to test it), and writes
it to the output stream as a txt attachment.
This JSP works perfectly well on SP1, however, on SP3, it fails only during the
first hit. If you call this JSP again from the same browser window - it'll work.
Needless to say - this isn't an acceptable behavior for a website.
Hope you can help.
Appreciate any response.
Roy.

Or do we have to wait for SP4 ?

This is a known issue and has been fixed.
The fix is in SP4. This has to do with a bug that IE has with respect
to a
header:
Cache-Control: no-cache="set-cookie"
We introduced that as the default header to be returned on all
responses.
As of SP4(due out very soon), the default behaviour will be notto send
this
header back with each response.

Why I have 3 empty ligns in the file downloaded with a JSP

Hello,
When a user select some data (extracted from an Oracle database), he could save the data in a flat file. To do this functionnality, I use a JSP which creates a file with the result of the query, and I download to the browser the file by using :
response.setHeader("Cache-Control","no-store");
response.setDateHeader("Expires",1000);
response.setContentType("application/x_msdownload");
response.setHeader("Content-Disposition","attachement;filename=" + outputFile);
I could save or open the file.
BUT I have 3 empty ligns at the begining of the downloaded file.
Do you know why?
Next, is it my code of the JSP used to create the file on the server, download it to the browser and delete it:
<%
currentReport.load(currentConnection, reportNm, whereCond, inputFile);
response.setHeader("Cache-Control","no-store");
response.setDateHeader("Expires",1000);
response.setContentType("application/x_msdownload");
response.setHeader("Content-Disposition","attachement;filename=" + outputFile);
File fin = new File( inputFile);
if (! (fin.canRead() || fin.isFile()))
SecurityException se = new SecurityException( inputFile);
throw se;
BufferedReader br = new BufferedReader(new FileReader(fin));
while ((currentLine = br.readLine()) != null)
out.println( currentLine);
br.close();
currentReport.deleteReport();
response.flushBuffer();
%>

I wouldn't use JSP for this, I'd use servlets...
But the reason is cuz you have 3 lines before the data is written, say like this:
<@page import="..." >[newline]
<@page import="..." >[newline]
<%
response.setHeader...
%>[newline]
<%
code to get the file...
%>

File Download in JSP, Please help

I am wondering if somebody can help me with a problem :
I am trying to register a fact that somebody has downloaded a file
from my company's website.
When a user clicks on the link I provided, a message box came up to prompt user with the location to save the file. How can I register the fact that user press "Cancel" instead of OK. In other words I need to be able to tell whether the guy really downloaded it or not.
Thanks

So, how to determine if user had pressed 'Cancel' or just the connection is broken?
The pure JSP cannot do it.
I think you should have some binary code like applet or active-x to check it.

*C:\project\webUpload\build\web\fuploads\file2.jpg*
*it may allow like :*
*\webUpload\fuploads\file2.jpg*
Thanks</a>

My friend you are getting it all wrong here...
Here we would be taking help of a dedicated servlet to locate and download a file(which would be the output the respective concent of depeding of the fineName or fileId you send in).
Please find some time and try to consider the below case...
Say i have a Servlet which takes a Request of detailed filePath and would give output as file itself....
and you prompt you give a link to that servlet from you JSP to download that file...
Checkout the below Code snippets to get some idea

Here is a hint for you...
Try to maintain a properties file which has a key value pairs of that something like.
112345678=C:\\uploadfile\\image1.jpg
122142637=C:\\uploadfile\\image2.jpg
or create a Database table which which an autogenerated primany key with some Id and holds the complete filePath.
and in this case you would access the file something like the one below from your jsp
<a href="FileServlet?fileId=112345678" title="112345678">Click Here to download Image1 JPEG File</a>
<c:forEach var="fileId" items="${sessionScope.fileNames}">
 <a href="FileServlet?fileId=<c:uri value="${fileId}"/>" title="<c:out value="${fileId}"/>">Click Here to download</a>
</c:forEach>
-------------------------------------------------------------------------and in the fileServlet you might have to change the below part to
// getting fileName which user is requesting for
 String fileName = request.getParameter("fileName").replace('\\','/');to something like
// getting fileName which user is requesting for
 String fileId = request.getParameter("fileId");
 /*Querying the database or reading the Properties file to findout the correspoding filePath associated with the fileId something like*/
 String fileName = ResourceDelegate.getInstance().getFile("fileId").replace('\\','/');
NOTE:* The idea is similar to what my fellow poster is trying to explain you in all his posts.
Hope that might help :)

Can any body give me code for file download in jsp

Hi all,
I have done file uploading to a particular dir C;\uploadfiles, and store the name of the file with other information in a table. Now I want to download that file of any format from that dir using jsp or servlet.
Can anybody please help me with some code.
Thanks and Regards
Rajib

This seems more like a job to a servlet
public String getContentType(){
this should return the cntent yupe of the file
that shoule be downloaded
if unknown use something like binary/data
public byte[] getFileData(){
This should return the data of the file as a byte array
public void doGet(......................){ // or doPost
   res.setCotentType(getContentType());
   OutputStream os = res.getOutputStream();
   os.write(getFileData());
   os.close();
}Above is the most simplest way to do it
and havent been tested you might need changes based on your program design

File Download with Servlet

In my application i have to download a file with the help of servlet.
Everything works fine except the case where i want to open the dialog box or just let that file open in the browser.
For e.g. when i am trying to download an excel file and i want to have a dialog box open for save, it doesnt does that but automatically open the file in browser.
But for the above case if i dont set the "ContentType" as "application/vnd.ms-excel" then it works fine like it will open a dialog box if in the header the value of "Content-Disposition" has "attachment;" and will open it if it has "inline;"
Could you guide me to some good study material on what can be issues or the fundamentals of setting the "fileName with extension", what if i dont set "ContentType" and what is the difference between "Attachment" and "Inline"
Thanks

actually youre using the trick most ppl use.. force the content type to be something else than the ms-excel..
the content type is ment to be a guide to the browser on how to interprete the content..
if it doesnt it will prompt you to download i.e. show the file save dialog..

File download using jsp

I am trying to download a file from the server using jsp but it always shows the file in the browser.I want a Save/Open dialog box to allow the user to save this file in the local system. any feedback is welcome.
thanks in advance
vinod

Basically out frame work is in struts.........
In struts for file down load I wrote the code as
String fileName = <file name>;
String filePath = <file path>;
String fileType = fileName.substring(dotIndex+1,fileName.length());
ServletOutputStream out = httpservletresponse.getOutputStream();
if (fileType.trim().equalsIgnoreCase("doc"))
httpservletresponse.setContentType( "application/msword" );
else if (fileType.trim().equalsIgnoreCase("xls"))
httpservletresponse.setContentType( "application/vnd.ms-excel" );
else if (fileType.trim().equalsIgnoreCase("pdf"))
httpservletresponse.setContentType( "application/pdf" );
else if (fileType.trim().equalsIgnoreCase("ppt"))
httpservletresponse.setContentType( "application/ppt" );
else
httpservletresponse.setContentType( "application/octet-stream" );
httpservletresponse.setHeader("Content-disposition", "attachment; filename=" +actualName );
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(filePath));
BufferedOutputStream bos = new BufferedOutputStream(out);
byte[] buff = new byte[2048];
int bytesRead;
while(-1 != (bytesRead = bis.read(buff, 0, buff.length)))
bos.write(buff, 0, bytesRead);
I hav written this in seperate function which returns boolean true If this works correctly otherwise fase.
If it is 'true ' I am forwarding it to 'success.jsp' else'fail.jsp'....................
Now problem is It is not forwarding to any other pages and giving error as "Illegal state .can not forward.Response already committed."
I think this error is coming becos of 'response.setHeader()' and using out object.........
Please give me any solution for this problem.........Since I am strucked here.It is urgent for me to do...................................
I don't mind If u giv any alteernative code for this..............
Thanx in advance..................
Plz. respond quickly...................
