I'm uploading an Excel document from a JSP to a Servlet. I'm using Apache Poi to read the Excel file. My exact requirement is to get the sum of the values of a known column.
Please tell me if there's a direct way than iterating one by one

The question is very simple but I've never seen it asked on stack. Will Apache POI work with a shared excel (meaning the excel is "co-authored" with other accounts as per Excel verbiage)? Will I still be able to create a pivot table using Java? How about upload a file to a certain cell?
Thanks.
I have a Excel sheet, with some columns(Column1, Column2, Column3, Column4). I want to read only rows with Column4="A" value using Apache POI. Please share any working example. The relevant information is not available within Apache POI website with example. Also, I want to copy the filtered set to another excel sheet. please share sample code.
Can we create multiple pages in an excel file using Java, if possible using Apache POI library? I tried googling it, but it returns how we can create multiple sheets. However, we are looking for multiple pages in the excel sheet.
Thanks,

I read this article. The program (from website) allows the user to generate a customized Word document use Apache POI. I found the code from these two websites that can generate Excel file use agent, however the output is generate the view in Excel format only.
Is it possible to export view to Excel in specify format without use Apache POI?
Instead of using Apache POI, is it possible to write code in agent to generate a customized Excel file?
No and Yes. You deal with Java on XPages. You could reinvent the wheel and write all was POI does yourself, so yes you could.
You also could output a HTML table but send a header of application\vnd-excel to get the table automatically opened in Excel (but no formula here)
What would stop you from using POI?
How do I export a trinidad table into an excel format?
I have <tr:table> and some values in it that are displayed using <tr:column>.
I want to export those values into an excel sheet.
You can't generate Excel sheets using Apache Trinidad. What you need to do is write an action which:
converts the data to an Excel sheet (for example using Apache POI or Java Excel API) and
gets the HttpServletResponse, resets it, sets the correct headers and outputs your Excel sheet.
