JSP is indeed a Server side technology. Here are few of the links to do a file upload using JSP.

Hope this may help solve your issue.
JSP is code that produces the client facing HTML code (commonly called the View) and the Servlet is server code. In reality they will be on different machines, so what is the use of the full path. The file contents should be POSTED to the servlet when submitting your form.
your jsp should something like:
<form action="UploadServlet" method="post"
enctype="multipart/form-data">
<input type="file" name="file" size="50" />
<br />
<input type="submit" value="Upload File" />
</form>
Of course you have other input fields as well.

The Local filepath is useless on the server-side. It would only be of use to hackers. That's why browsers don't send it. Its a security measure. You should be glad its there. I'm surprised none of the existing answers pointed this out.
On the server-side you decide where to save the file. You wouldn't want the user deciding that, obviously. Giving them the ability to decide where to save the file on your server would give them the ability to overwrite your system files.
