Problem displaying an Excel File: Please Help

Hello,
I spent 3 hours this morning reading the forum on how to display an Excel file in the browser using JSP and I apologize in advance if the answer is in the forum.
I cut and paste many examples: My goal is to display an excel file on the browser.
Below is the code but the result is a disaster (please se after the code the result).
My question is how can I display an excel file using the browser. What's wrong with my code. Apparently it worked for many people on the forum.
Please help. I must do that by tomorrow and I had spent already so many hours.
THANK YOU SO MUCH IN ADVANCE.
So far the forum had helped me a lot.
<%@ page language="java" import="java.io.*" %>
<%
String myfile = new String("/temp/temp.xls");
File fileName = new File(myfile);
// Setup our streams
FileInputStream fis = null;
ServletOutputStream out1 = response.getOutputStream();
// Set content type and other response header
response.setContentType(getServletContext().getMimeType(fileName.getName()));
//response.setContentType("application/excel-document");
//response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment; filename=\"" + fileName.getName());
response.setContentLength((int) fileName.length());
// Read in the file from the correct place and stream it to the user
int iRead;
FileInputStream stream = null;
try
stream = new FileInputStream(myfile);
while ((iRead = stream.read()) != -1)
out1.write(iRead);
out1.flush();
} catch (IOException i) {}

For those who are having the same problem than me here the solution:
In fact I was only interested in saving the file

String myfile = new String("/temp/temp.csv");
response.setContentType ("application/vnd.ms-excel");
response.setHeader("Content-Disposition", "attachment; filename=\""+myfile+"\"");

ServletOutputStream out1 = response.getOutputStream();
FileInputStream stream = null;
try
stream = new FileInputStream(myfile);
while ((iRead = stream.read()) != -1) {
out1.write(iRead);

Oracle reports to display PDF/Excel files stored in the Database

can we use Oracle reports to view/display PDF/Excel files stored in the Database? Thanks Lalitha

A document stored in the database can be easily retrieved in or via the browser using mod_plsql. Simplified:
select content, mime_type
into v_blob, v_mime_type
from ...
owa_util.mime_header(nvl(v_mimetype,'application/octet'),false);
htp.p('Content-length: ' || dbms_lob.getlength(v_blob));
owa_util.http_header_close;
wpg_docload.download_file(v_blob);So, the link in your report should point to this database procedure.

somebody knows how could I do this?
Any suggestions?

There is quite large dedicated Excel thread with a lot of examples.
I'm curious though. If you don't have the toolkit, how did you create the Excel file in the first place?

Best ways to view/display PDF/Excel files stored in the Database

What are best ways to display/view PDF/Excel files stored in the Database? thanks L

Thanks tom, sorry let me explain. Currently we have oracle forms screen, using webutil to store/view files into DB. client won't like the interface, they want us to make it more friendly, drag and drop if possible, load multiple files, as possible.. So I am exploring different ways to improve may be java (or jdev/any any other), different screen designs, different features for fileupload/download/view options.

Problem with french character display in Excel file

In my program I am exporting the french content into one excel file (.csv)through the following code but the characters in french are not getting displayed properly. Please let me know what is the issue
I have checked the contents that is being written in "fileName"
It is French only. But when the file is downloaded to desktop, it is showing junk characters in .csv file
============
if (fileName != null) {
File theFile = new File(fileName);
if (theFile != null) {
try {
     byte[] bytesFromFile = exportUtil.getBytesFromFile(theFile);
     response.setContentType("text/csv; charset=UTF-8");
     response.setHeader("Content-Disposition",
          "inline;filename=" + theFile.getName());
     response.setContentLength((int) theFile.length());
     ServletOutputStream sos = response.getOutputStream();
     sos.write(bytesFromFile);
     sos.flush();
     sos.close();
} catch (IOException e2) {
     e2.printStackTrace();
}

Have you confirmed that the file you are copying to the response is actually encoded in UTF-8? Because you're telling the server that it is. If it's in some other charset then naturally it isn't going to look right.

IMac 2.66 Radeon HD 2600 Pro: some Excel files won't display in ppt decks

Running Leopard 10.5.8 and MS Office 2004
Two iMac (8.1) 2.66 GHz with ATI Radeon HD 2600 Pro video won't display some Excel files in PowerPoint decks, but iMac 1.83 GHz Core Duo will display o.k. as will MacBook Pro, MacBook, etc. Installing a trial version of Office 2008, both iMac 2.66 GHz display the PowerPoint files o.k.
I could downgrade the users to Intel iMac 1.83 GHz, or buy two copies of Office 2008 and support them, neither of which is a great solution.
Looking for a simple fix or workaround on what seems to be a video card issue. Don't seem to see this problem or a fix on the ATI site. I've googled this but haven't run into a similar issue.

Well, Office 2008 is only $110 USD at http://www.amazon.com/Microsoft-Office-2008-Home-Student/dp/B000X86ZAS/ref=sr11?ie=UTF8&s=software&qid=1251560959&sr=8-1
That seems the least expensive solution to me.

Problem excel file display in my workset ...

Hi everybody,
I create a Workset, a page and a basic iview about an URL.
It works.
Then, i create an iview (template KM document) which must display an excel file.
I add to my Page and i visualize a glimpse: i see the right excel file in an HTML window.
Problem appears when i execute my workset ... It doesn't work. I see a blank page!
Any suggestions ?
Thanks,
Rodolphe.

How to edit a spreadsheet (excel file) in the portal?

Hello experts,
at the moment i am working on the requirement to edit a spreadsheet in the portal.
Until now i was able to display an excel file with the help of the 'KM Document iView (without content filter)'.
Everything is displayed alright and i can perform changes in the spreadsheet.
BUT: There is no such thing like a Save-Button or something like that. Does the SAP NW Portal already provide a solution for this requirement? Or will i have to develop an own application?
I have already searched the forums and sap help, but i haven't found any solution. I can't imagine that such an easy requirement would need coding.
Best Regards
Marcus
(Po*nts will be rewarded for good answers)

Hi Marcus,
I do not think you can do the task the way you want. You will have to look for some workaround that may be download the file, edit it and then upload it back. You will have to code in your application for that. If you want to do this way I can help you further to edit and save the excel.
Regards.

Opening Excel files from a JSP page

Hi,
I am not able to open up an Excel file through JSP.
I am using following code snippet in JSP page
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","inline; filename=Test.xls");Do i need to do additional settings for rendering Excel from a JSP
Thanks in advance !!!

Hi,
In my application , we have Excel files on the server i.e we are not creating excel sheets.
I just want to display these static excel files through a jsp.
I am able to display the excel files by reading them into ByteArrayOutputStream
<%
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment; filename=B.xls");
ServletOutputStream so = response.getOutputStream();
String filename = "D:\\Test.xls";
String mimetype = "application/vnd.ms-excel";
ByteArrayOutputStream output = new ByteArrayOutputStream();
InputStream in = new BufferedInputStream(new FileInputStream(filename));
byte bytebuff[] = new byte[500];
for(int lengthread = 0; (lengthread = in.read(bytebuff)) != -1;){
output.write(bytebuff, 0, lengthread);
byte data[] = output.toByteArray();
response.setContentType(mimetype);
so.write(data);
in.close();
so.close();
%>But my question is that , do i really need to do all this for rendering excel through a jsp.
Can't i do it by just setting the content type ?
Thanks

Hi.
I find that
List > Export > Spreadsheet
gives no subtotals, but
List > Export > Local File and then Spreadsheet
does give subtotals.
I find that
Views > Microsoft Excel
followed by
Save As
does give subtotals.
