I have a zip file physically stored in database.
I need to read the file from database and download it .
When I tried to get the data from database using getAsciiStream and wrote it using FileWriter zip file got created but unzipping the file gives error..
I also tried unzipping the zip file but that also gave an exception
If you attempt to present a ZIP file from a JSF view, JSF will corrupt it. Same for PDF's, Word documents, Excel spreadsheets and any other non-HTML file format. JSF is expecting to output HTML and only HTML.
Use an ordinary servlet to present the ZIP file for download. JSF is not greedy, it won't mind.
