traansfer of files between jsp pages.

i am trying to create a dynamic web project which performs XOR operation on a file uploaded by a user by converting its contents to ASCII code. i got the process to upload a text file and put it on the servlet. this is the code ive been able to do:

<form name="formLogin" method="post" enctype="multipart/form-data" action="Encrypt1.jsp">
     <table width="100%" border="0" cellspacing="5" cellpadding="2">
        <caption> Upload file here </caption>
                <tr valign="bottom"> 
                <td class="smallgrey" valign="baseline">File:</td>
                <td  valign="top"> 
                <input name="file" type="file" id="file"  />
                    </td>
             </tr>
                   <tr><td><input type="submit" value="submit"/><input type="reset"/><br /></td></tr>
                         </table>
                 </form>

now i dont know how am i supposed to retrieve this file in the next jsp page. and moreover am i supposed to do anything more in order to make the file move via servlet?
