I haven't done it using JSP but in a servlet you can set a response header, then return the data as a HTML table and Excel will parse it.
The servlet code to set the header is
response.setContentType("application/vnd.ms-excel");

Error in Open Excel Files from JSP..it display Eksponen...

How to set Excel format in JSP? - Error in Eksponen.
Hi, i have a problem.
I am using JSP to select data from database and open it as an Excel file.
It works perfectly, but the problem is,
when the data is NUMBER (even though in JSP, i declare it as a String), in the Excel file, when the data is more than 10, the data will change to Eksponen value.
Should be = 982520000324464
but in Excel is = 9.8252E+14
Can anybody help?

Depending on how you are generating the Excel file there are different solutions.
If you are generating the Excel file using contentType="application/vnd.ms-excel" and HTML tables, then you can use the following attribute on the cell you wish to format:
<TD style="vnd.ms-excel.numberformat:#,##0;">24.562234</TD>where the #,##0 corresponds to the format you wish to present the data in.

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 am too facing the same problem. I am using Jakarta Poi to display my resultset in an excel sheet directly(and not into a jsp)
The browser opens a window showing Open Save Cancel. If i click and save the excel sheet and then open, it opens. But clicking on Open directly doesnt open the excel sheet. Rather it gives the same error
The file name or path name does not exist.
The file you are trying to open is being used by another progrtam . close the document in other program and try again

How to list all currently open Excel files with ActiveX?

Hello all!
I would like to program with ActiveX a way to retrieve a list (array of strings) of the filenames of the currently opened Excel files in windows. However, I am fairly new to the ActiveX/Excel business in LV and after hours looking at the "millions" of objects in the property nodes I give up and hope some kind soul here can help me. I couldn't find any information in this forum regarding the same issue, although some were close
I am using LV 7.1 without the Report Generation Toolkit.
Thanks!
/Goran

Hi KC,
thanks for your reply. I have in fact been able to find the desired things in the ActiveX properties/methods for Excel in LabView. It took me some looong work going through the functions which I suspected to be the ones. Anyway, I post a little jpeg here of the code if someone ever needs the same functionality. What it does is that it checks how many Excel workbooks are open and controls if each of them matches the searched Excel filename, if one does, it is closed.
Enjoy

Some users can't open Excel files. It is trying to open it in Internet Explorer "An error has occurred. Please try again."

I have some users in my company that can't open Excel files from any document libraries on SharePoint 2010. The receive the error message "An error occurred. Please try again."  We don't currently use the Excel calculations services. When
a user opens an excel file they are prompted to either Read Only or Edit.
This affects less than 5 people in a large company. They have the Full Control permissions and have been able to open the files previously. There has been no changes made to the server either. I can't find anything that points to this in the
event viewer.
It doesn't matter if which computer that they try to open this up from either.   All computers are Windows 7 Professional with IE 9 and Office 2010 x64.
I can't find anything that points specifically to this exact error. None of the excel files contain pivot tables.    This one has me stumped.

I would make sure no one has open on machine / locked on machine (Would assume you checked this, but wanted to add)
Also would have assumed you restarted the machines (:))
Make sure the file security did not change (check to ensure no one changed the sercuity of the excel)
Make sure the version of excel is the same (Changing from 2010 back to 2007 affects the file, etc.. on convert) that no one converted and saved thus causing error in file.
Can they open other excel files?
It sounds like the excel file it self has changed if you cannot see issue in SharePoint logs.
If it is all SharePoint excel files - try deleting one persons access and readding them to see if that helps.
SharePoint has issues ;)

Cannot open Excel files on Windows share and ONLY Excel files

I'm browsing a Windows share and for whatever reason it will not let me open Excel files directly from the network location. If I view the Coverflow, I can see a a preview of the actual file as well as copy it to the desktop and open it.
I receive an error message that says "filename.xls could not be found."
I can open up any other file from the network location, but not Excel files.
I checked the file permissions and they mirror the other file types, it may be worth mentioning that I utilize network synchronization and view these files from a PC as well. I also noticed when I create a new file in that location, it will only appear in OS X and not Windows, but is still completely accessible.
Any help is appreciated!
Thanks

Can't open Excel files from Sharepoint 2013

I am having an issue with opening Excel files from SharePoint 2013. If I click on an excel file it comes up with the error below.
If I click Try again I get the message below also:
If I try to open Word or PDF files they open correctly in the appropriate client and I have the option of checking them out and editing them. Any ideas why this would only be happening to Excel files?
Thanks,
Shaun

Hi Shaun,
I understand that the Excel files cannot be opened from SharePoint in Microsoft Excel.
Can these files be viewed in the browser?
I recommend to download a copy of the files with issue and then open them in Excel to see if the issue still occurs.
If above cannot work, I recommend to repair Office.
Best regards.
Thanks

When Opening Excel file, there is a message

Dear BPC Experts:
When I open excel files in BPC NW 7.0, there is a warning message saying "Programmatic access to Visual Project in not trusted"
Does anyone have suggestion for this message? Thanks in advance.

From MS Excel 2003 goto Tools > Macro > Trusted Publishers > check on the option Trust access to Visual Basic Project. From the Security Level tab - click on the Medium option.
From MS Excel 2007 click on Office button in the top-left corner, then click on the Excel options from the pop-up window. Click on the Trust Center option > Trust Center Settings > Check on the option Trust access to the VBA project object model. Also check the option Disable all macros except digitally signed macros.

Cannot Open Excel File after exporting from Disco Plus

Hi there,
I got a question from one user having issue with opening Excel file after exporting from Disco Plus.
The report has been using for a while and he is using Excel 2003 version and Discoverer 10g(10.1.2.2), he never got this kind of error before, just recently got error.
After exporting from Disco Plus he saved file on his desktop and when he tries to open the excel it says "Cannot be Accessed, can be corrupted...." but this is not from network drive since he saved file on local desktop or C drive.
Also not for all reports, only this particular report and only specific parameter, for example for parameter 2008 Feb opened successfully, but for2009 Feb he gets this error when trying to open excel.
i tried in excel 2007 also , i dont think this is Excel version error, am not sure.
Also after go live last week (we upgraded database from 9i to 10g) but i am not sure this causes ,since for one parameter working, for other parameter not working.
Actually we should get one window for Macro when we try to open excel, but he is not getting it seems.
Any ideas/thoughts on this would be greatly appreciated.
Thanks for your help
--skat

Rod,
Thanks for your quick response on this.
Yes, we can export to other formats as well, but actually exporting is working, after saving the file on our local desktop/drive and when we try to open we get this kind messages or we cannot open the file, we should get message window for Macro to enable/disable but for this report we are not getting this either,
Also this happens only for specific parameters,like i mentioned above it works I mean excel file opens for one set of parameters but for some other set of parameters cannot open.
For example :- when we enter FEB 2008 it works, if we enter FEB 2009 it won't open the file.
This is weird
I am still working on this issue, may be better to recreate the report again might be helpful,
Any ideas/comments/thoughts would be great
Thanks
Skat
