Export csv

Export to Excel JSF and PrimeFaces. I am trying to download CSV file which is created in runtime. This link is useful for excel and I need to do the same for CSV. HSSFWorkbook is used for excel but I am using FileWriter for CSV. When you click the export option, there is no option to export to Excel. The only options are: Crystal Reports (RPT) Adobe Acrobat (PDF) Microsoft Word - Editable (RTF) Rich Text Format (RTF) Comma Seperated Values (CSV) We used to use the JSF components to connect to a Crystal Report server and that displayed both Excel and Word (DOC) formats.
