Download Excel file using JSP

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

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 Bangalore:
As my experience,there may be some symbol such as "\r\n" was added in the content of the Excel file you want to download. this is no porblems to text format file, but to binary format file, such file can not be open. So I suggest you check-up the content of the file befor it was writed to the client, remove unwanted symbol, it should be word!
I'm a newer to the here , and my english is poor. I thirst for intercommunion, I'm sorry for the syntax error in my reply.

Hi,
You can use this function GUI_EXEC.
Let say you want to use winzip to zip the file then what you should do like this:
use this command --> ' -min -a D:\WALCOTT.ZIP D:\MBARANG.TXT'
D:\MBARANG.TXT --> path to the file you want to Zip
D:\WALCOTT.ZIP --> result zip file
The command above is depends on the software you use to zip.
then
DATA: cmdguiexec(150).
cmdguiexec = cmd.
CALL FUNCTION 'GUI_EXEC'
EXPORTING
command = cmdguiexec.
Hope this help you.
Best Regards,
Victor.

Opening an Excel File using Excel 97 from a JSP populated page(Urgent)

Hello,
I am using a JSP Page to populate data from the DB.
When I am opening the same as an Excel File the JSP code is coming as the Excel page whenever Excel 97 is being used,but when Excel2000 or 2003 is being used then the data are coming as Excel formatted.I used the following code(JSP) :
<head>
<%
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","inline; filename=ExtractData.xls");
%>
</head>

I can't even tell what the difference is between "coming as the Excel page" and "coming as Excel formatted". But then when people make urgent posts they very rarely spend the time to describe the problem accurately. Why bother when it's so damn urgent?

Hi,
Peter Gjelstrup wrote:
Next thing is how to use it:
declare
k_file constant varchar2(30) := 'YourFile.xls'
begin
create_file(k_file);
-- Call other procedures
close_file;
end;
Don't forget: these procedures are all part of the gen_xl_xml package.
To call them from outside the package, you have to prefix each procedure name with the package name, like this:
declare
k_file constant varchar2(30) := 'YourFile.xls'
begin
gen_xl_xml.create_file(k_file);
-- Call other procedures
gen_xl_xml.close_file;
end;

URL Link on downloaded Excel File

Hi,
I have got a requirement.
For study and analysis purpose user download data on excel file from OCOD. Struture(Contents) of downloaded excel file is same as screen.
But the problem is when user click on 'DETAIL' (which has URL link) he/she is directed to Live OCOD and asked for log in with ID and Password, even if
user is logged in OCOD.
What i want to do is.
1) Download Excel file without any URL link.
2) If 1) is not possible then do not want to have 'DETAIL' option of downloded file.
3) Method for avoiding relog into OCOD.
Thanks in Advance

Download Excel file from from a second server

Hi,
In our Java based web application (jsp pages) users need to download Excel files stored on a different server (business tier) than the first application server server that hosts only the presentation tier.
For security reasons users don't access the second application server. From a technical point of view what's the best solution to answer this requirement ? The logic should be the following: the user clicks on a report name that is displayed on this browser, the request is sent to the first application server that will retrieve the report stored on a second server and will return it to the user.
Thanks a lot.

it's been a while since i've done ejb stuff, but i believe you can configure an ejb to "runas" a different user. so, you would configure an ejb on the accessible server to "runas" a user who has access to the secondary server.

Filename of downloaded Excel file

I frequently download Excel files from a website that seems for the most part windows centric. These excel files have an extension of .xls, I can double click them to open, but when opened they just have the file name of WORKSHEET. If I rename the file in the finder the same thing happens. If I try to open the file in numbers I get something like
<table border="1">


<tr><td colspan = "15" valign="middle" align="center">Investor's Business Daily 100</td></tr>
<tr><td colspan = "15" valign="middle" align="center">Data as of 8/1/2008 market close</td></tr>
Any idea? Now I have to open the file in excel, then do a save as, type in the file name (if I don't want WORKBOOK), then delete (or write over) the original file. What can I tell the website people?

Hello ,
In my procedure i am passing id and with the help of that id , ia am fetching values from the database.
i have declared on clob type variable say v_insert where i am storing table structure(like worksheet) which i need on excel
example
v_insert := v_insert||'<tr>';
v_insert := v_insert||'<td></td> <td></td> <td></td> <td></td> <td></td> <td></td> <td><b>Column1_Value</b></td> <td>abc</td>';
v_insert := v_insert||'</tr>';then i am converting that clob into blob and storing the content into BLOB type variable say v_blob
below is the code used for downloding the blob content.
wpg_docload.download_file(v_blob);Thanks,
Jitendra
