JSPs are not meant for this kind of thing; use a servlet instead that can handle the upload at the server side, and which then forwards the request to a JSP which can show the result. The Jakarta Commons FileUpload library can handle the file upload part.

If you mean by 'doc file' a Microsoft Word document, then you can't. Not with JSP alone anyway.
There are third party libraries such as POI for working with Microsoft Office formats from Java. You might need to look into one of those. If you can reasonably expect your users to have Microsoft Office or something that can work with Office files (Like Open Office), then you might consider writing a servlet that streams the document, as is, to the browser.
