i m creating an application which queries the database and store the result in excel sheet on application server which runs under unix operating system. i m providing link to download the excel sheet in jsp page. it is working, but the problem is that whenever it is downloading the excel sheet it is in ascii mode because of which i m not getting file in excel sheet. is there any other way where i can set download mode.
If your just providing a link to a file, the server should take care of this for you. You may need to add a mime type entry for a particular file. In Tomcat, the mime types are in the global web.xml (the one in the conf directory).
If you're streaming the file to them from a database or location outside of the sections of your app that are accessible to browsers, you'll need to set the content type and the content disposition headers.
I have an example application that streams images from a directory under WEB-INF. It should have enough code to get you going. http://simple.souther.us Look for SimpleStream.
