Not sure why this code isnt working for me, it makes an empty excel file called output, but never copies the contents in "myfile" to that output file. I have Excel 2010 but I saved both of them as 97-2003 workbooks. Am I missing something? Do you have to go cell by cell to copy an excel file with JXL?

View Replies View RelatedI have a requirement to download the data from DB to CSV/Excel. What I did is retrieving all the records from DB and store in the List and pass that list to the jsp page. In JSP page, I am using the below setting to download it to CSV/EXCEL.
response.setContentType("application/vnd.ms-excel");
String fileName = "Report"+System.currentTimeMillis()+".xls";
response.setHeader("Content-disposition","attachment;filename="+fileName);
It was working fine. But I have an issues in it. Excel is capable of storing it only 65,536 rows. Even all the data getting downloaded to CSV/excel (> 65,536), while saving I am getting error from excel saying that it can't save more than 65,536 rows and the below data won't be saved.
This workbook contains data in cells outside of the row and column limit of the selected file format.
Data beyond 256 (IV) columns by 65,536 rows will not be saved.
Formula references to data in this region will return a #REF! error.
I am not opt for POI apache third party at this point of time. Is it possible to download it in other sheets if it exceeds the max limit.
Example: Having data of around 100,000.
Download 65,536 - Sheet 1
Remaining in Sheet 2,3.. of the same excel.

I am currently looking for a best option to show the content of a workbook or an excel in browser on the fly of generating the workbook.
Currently, I am able to save the content as an xlsx file which is actually taking space in the temp folder while creation. This becomes an overhead for the user to delete the temp files manually.
So I am thinking of bringing the content of the generated excel file on the screen and give an option in the screen to download that into file.
In detail - currently,
ServletActionContext.getResponse().setContentType("application/vnd.ms-excel");
ServletActionContext.getResponse().addHeader("content-disposition",
"attachment; filename=" + filename);
Instead of creating a file, I want to the excel items to be shown on the screen on the fly.
