Streaming an xcel file using servlets

[sonia pandit]

How do I read an excel file using servlets. I have done it using poi. But I want to avoid using poi libraries.
Any way out?

Read it and do what? If you just want someone to upload an Excel file and save it then use a file upload library.

I would like to be able to open the file in excel format n the browser.

Then just stream it to the client; if their browser is set up correctly they'll be asked to open or save it.

In order for a servlet to open it I have to set the content type correct? Not sure what else I have to do.
But how do I set the content type;

See the ServletResponse docs.
