I'm going to set up a simple jsp which allow user the upload file. But I have not idea how the jsp syntax should be. If my html from is as follow:

<form type="post" action="upload.jsp">
    <input type="file" name="upfile">
</form>

then how the upload.jsp should be?
I just want to save the file in the same directory of the jsp.

Pls help
