Hi, I need some help woth downloading .CSV file with the regular ServletResponseObject, it is adding unwanted characters (2 boxes) in the end of the file when I download it. Your help would be greatly appreciated!
I have a download.jsp file, that calls a manage bean downloadfile.java to render a file, it is all working well with the excaption of downloading .CSV file. The problem is that when I try to download a CSV file, by clickin on the link, thats calls the Download.java bean which set the Response object, and opens up the "Download File Diaglog - Open/Save As", when I open/save as the CSV file, it added unwanted characters at the very bottom of the file. Even when I tested to upload a totally empty file, when I download it, it added the unwanted characters (2 Boxes) , where it should have been empty. Orignally, I have the <html><body>..etc tags on the download.jsp, and all of those HTML code were added to the end of the CSV file in addition to the unwanted file. So, I removed all of the unnesscary <html> tags, and the HTML codes are gone from the CSV file, but the unwanted characters are still being added at the end of the file. I have no idea how it got there.
