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 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.

Urgent : Download file from Application Server via Process Chain.

Hi Experts,
My requirement is to download the file from Application Server to local work station using an ABAP Program .
I want including the above ABAP program in a process chain to execute the program daily,
I tried to use ARCHIVFILE_SERVER_TO_CLIENT and GUI_DOWNLOAD but unfortunately both the above FM doesn't support to run through Process chain.
Can any one of you help me to send the code which selects a file from application server, downloads to local system and deletes it.
Thank you very much for spending your precious time in this regard.

Hi Sailekha,
Regarding your case ..
I suggest you to create the program where it run this function: WS_DOWNLOAD.
After it, the program is run by your process chain.
Hopefully it can help you a lot.

How to download a text file using jsp i

I want to provide download facility in jsp page.
if i have exe download is working . If I have a text / html file it is just displaying I want to make it download How to do it?
regards
subrahmanayma

If you want to get an "Save as" dialogue, then you need to set the content-disposition in the header to "attachment". The default value is "inline".
Best solution is to create kind of a FileServlet and let it stream the right file as a download to the client. You may find the downloadFile() snippets at the bottom of this article useful: http://balusc.xs4all.nl/srv/dev-jep-pdf.html Put it in a FileServlet and call it using for example .

Creating a file download link on jsp

I have the following on my jsp. The code worked fine until I tried to use it in a new html design page.
<code>
//page name is index.jsp
try //DISPLAY THE CONTENTS OF THE DATA DIRECTORY
File dirname = new File(PATH); // create an instance of the File class
if (dirname.exists()&&dirname.isDirectory())//check to see if File class dirname exists and is valid
String [] allfiles = dirname.list();//create an array of files in the dirname File class
          for (int i=0; i< allfiles.length; i+=2)//loop through allfiles[] and print out file links
out.println("<br><table border='1' cellspacing='1' width='99%'>");
               out.println("<tr><td width='50%' class='pageFont'><input type='checkbox' name='cb' value='"+allfiles[i]+"'>"+allfiles[i]+"      ");
%>
<a class="a" href="index.jsp?downfile=C:\\data\\<%=allfiles[i+1]%>">DOWNLOAD</a></td>
<% if(i+1 < allfiles.length)//PRINTS OUT THE SECOND TD SO THAT WE HAVE 2 COLUMNS OF LINKS
out.println("<td width='50%' class='pageFont'><input type='checkbox' name='cb' value='"+allfiles[i+1]+"'>"+allfiles[i+1]+"      ");
%>
<a class="a" href="index.jsp?downfile=C:\\data\\<%=allfiles[i+1]%>">DOWNLOAD</a></td></tr>
<%
out.println("</form></font></table>");
catch (IOException excep)
     out.println("An IO exception has occured.");
</code>
Then when clicked this code is run:
<code>
try{
//CHECK TO SEE IF THE FILE HAS BEEN CLICKED TO DOWNLOAD SINGLE FILE
if (request.getParameter("downfile") != null)
String filePath = request.getParameter("downfile");
File f = new File(filePath);//CREATE AN INSTANCE OF THE FILE CLASS AND POINT IT TO THE LOCATION OF THE DIRECTORY CONTAINING THE FILES
if (f.exists() && f.canRead())
response.setContentType ("application/octet-stream");
response.setHeader ("Content-Disposition", "attachment;filename=\""+f.getName()+"\"");
response.setContentLength((int) f.length());
BufferedInputStream fileInputStream = new BufferedInputStream(new FileInputStream(f));
int i;
out.clearBuffer();
while ((i = fileInputStream.read()) != -1) out.write(i);
fileInputStream.close();
out.flush();
</code>
When I click on this link I get the download dialog box. If I open it I get the following open up in notepad(the files I am trying to give download links are .txt files)
Below is what is displayed in notepad ALL on 1 line:
<html>
<head>
<LINK rel="stylesheet" ty
That is displayed in all of the links that I click on. It is the first few lines of html code for index.jsp.
I know this code is probably not a good way of doing what I need but I got it to work fine until the change.
I am sure there is an easier way to code the download link without resubmitting the page.
Thanks in advance!!

Well all was fine with this jsp until I moved it to ApacheJServ. Now the problem has resurfaced(although it is a little different now)
I had moved the following code to the top of my page:
//CHECK TO SEE IF EITHER DOWNFILE OR ZIPFILE VARIABLE EXIST, AND IF THEY DO SET CONTENT TYPE BEFORE SENDING ANY HTML CODE TO THE BROWSER
try{
//CHECK TO SEE IF THE FILE HAS BEEN CLICKED TO DOWNLOAD SINGLE FILE
    if (request.getParameter("downfile") != null)
            String filePath = request.getParameter("downfile");
            File f = new File(filePath);//CREATE AN INSTANCE OF THE FILE CLASS AND POINT IT TO THE LOCATION OF THE DIRECTORY CONTAINING THE FILES
                if (f.exists() && f.canRead())
                    response.setContentType ("application/octet-stream");
                    response.setHeader ("Content-Disposition", "attachment;filename=\""+f.getName()+"\"");
                    response.setContentLength((int) f.length());
                    BufferedInputStream fileInputStream = new BufferedInputStream(new FileInputStream(f));
                    int i;
                    out.clearBuffer();
                    while ((i = fileInputStream.read()) != -1) out.write(i);
                        fileInputStream.close();
                        out.flush();
                        response.flushBuffer();
catch (Exception e){}
//This is where the java code ends and the javascript/html code begins.Then further into the page I create the file download links like so:
                        <a class="a" href="main.jsp?downfile=C:\\data\\<%=allfiles[i+1]%>">DOWNLOAD</a>I know this isnt a secure way of doing this but I am on a intranet.
The problem I am having now is that when I click on one of the links and download the file and then open it, I get the contents of the file plus concatenated to the end of it is the first few HTML lines of the actual jsp that I downloaded the file from. Before I was just getting the first few lines of html from the jsp, not the actual contents of the downloaded file.
This is an example of what I am getting:
This is the contents of the file that I downloaded.//This is where the file contents ends.
<html>
<head>
<LINK rel="stylesheet" type="text/css" href="default.css">
<script language="JavaScript1.2">
//function that allows user to select all checkboxes
function doIt(v)
for(var i=0;i<document.form1.cb.length;i++)
   document.form1.cb.checked=eval(v);
function swap(imageName,image)
imageName.src = "templateImages/"+image;
function imageOver(imageSrc, imageName)
     changeImage = new Image();
     changeImage.src = imageSrc;
     document.images[imageName].src = changeImage.src;
var hide = true;
function hideShow( ) /
Any morre ideas?
TIA!
BTW, I went to ApacheJServ because they wont let me use tomcat :(

Converting an html file with jsp contents to a text file for download

Hi guys,
I'm currently having troubles with downloading a .jsp file to a doc file.
The thing is i am able to download the desired file and make it as a .doc but when i open it with ms word 2007 i can only see the content of the html. The dynamic content generated from the database and reflected on the .jsp page that i suppose to download and convert to .doc file doesn't show.. I hope someone could help me... My servlet code is this:
public class FileDownload extends HttpServlet
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
try
String originalFileName="localhost:8080//Appsdev//reportresults1.jsp";
File f=new File(originalFileName);
System.out.println("THE 1st f:"+f);
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment; filename=tryreport.doc;");
response.setHeader("Cache-Control", "max-age=0");
byte[] buf = new byte[1024];
FileInputStream inStream = new FileInputStream(f);
OutputStream outStream = response.getOutputStream();
int sizeRead = 0;
int size = 0;
while ((sizeRead = inStream.read(buf, 0, buf.length)) != -1)
outStream.write(buf, 0, sizeRead);
size += sizeRead;
inStream.close();
outStream.close();
catch(Exception e)
e.printStackTrace();
}

Hi BalusC,
sorry for the double post i'm newly registered and it's my first post before i was just reading other's threads.
well last night while i was reading and researching for a solution a came across this.
<%@ page language="java" contentType="application/msword"%> naturally for my other jsp pages, the contentType is text/html so when the page loads it display in the browser. But with application/msword when i direct the page to the jsp page that i want to download and set the contentType with that...it prompts a window like when you're downloading the one with the <open with and save as>. It works fine to, i was able to see the report that i have to download and it is formatted very much like what i am seeing on the browser. My only concern now is the file i am able to download is a .jsp file how could i change that to a .doc file and be able to see the same content like the one with the .jsp file that i have right now.... any help or examples would be greatly appreciated. I didn't use the servlet anymore because even though i am able to download there is no content the html parts only but iam able to change the extension for the file...thanks again! ^ ^

Download file urgent

Hi,
is it possible to download a file using gui_download which contains bold characters. now i am getting plain text only.
Example i want to download like this
<b>'download file urgent'</b>
but i am getting as
'download file urgent'
rgds,
Madhu

No, you will not able to retain the text formatiing while download.
If you are downloading the file in HTML or XML format then I think formatting can be retained but not for normal formats.

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...
%>

JSP, downloading files and show html page

I like to download files and show a html page on JSP.
With the source following, downloading works well.
But, it is just remained on the previous page, not showing the next html page.
Someone tell me why is it?
<%@ page import="java.io.*, java.net.URL"%><%
String file_name = request.getParameter("file_name");
File fileDir = new File(config.getServletContext().getRealPath("upload/"));
File theFile = new File(fileDir, file_name);
FileInputStream fin = new FileInputStream(theFile);
response.setHeader("Content-Disposition","attachment; filename=\"" + theFile.getName()+"\"");
response.setContentLength((int) theFile.length());
BufferedInputStream bf = new BufferedInputStream(new FileInputStream(theFile), 8096);
int i;
while ((i=bf.read()) != -1)
out.write(i);
bf.close();
out.close();
%>
<html>
<head>
<title>file download</title>
</head>
<body>
<p align="center"> </p>
<p align="center"><b><font face="Tahoma" color="#000000" size="2">You have
successfully downloaded your file(<%=file_name%>)!</font></b></p>
</body>
</html>

You's already close the JSP output stream befor you try and write your html confirmation, and I don't think browsers can provide the kind of functionality you're trying to demonstrate here. A browser will download the file and open it directly itself or using another application based on user input (e.g. save as, open file, etc.). Once the file is opened or downloaded, it's done!
I think your best bet is to show a dialogue that the user's download should begin, then set the pages href w/ JS to the location of the file, same way other sites that allow you to download files do it. Go take a look at download.com or something like that.
Hope that helps.

Uploading and downloading files from a web app (Urgent!!)

Hi everyone:
I'm developing an application in PL/SQL to upload and download files from an HTML webpage. I congured the document table and the parameters necessary in the DAD of my application.
when I upload the file using my webpage that file info is automatically uploaded to the doc table. This is as far as I have gotten.
I need to do the following:
- Place the uploaded file into a column in another table in my database as part of a text message (think of it as an email message), and delete the file from the doc table (as this is thought to be a temp table that holds the file when uploaded from my webpage)
- Retreive the file so that it can be downloaded from another web page.
The file can be a PDF, WORD DOC, etc...
I now that I can do this with InterMedia but I haven't figured out how :(
Can anyone please point me to an example or some documentation that can guide me through the process.
DB VERSION: 8.1.7
IAS VERSION: 1.0.2.2
Thanks,
Carlos Abarca

The idea was for you to look at the code and get an idea of how to access the BLOB in the document table. IF you look at the procedure
insert_new_photo( new_description IN VARCHAR2,
new_location IN VARCHAR,
new_photo IN VARCHAR2 )
It shows how to access the blob that is stored in the document table. You can then copy this blob to your own table using the DBMS_LOB package.
Hope this helps,
Larry
