File Delete using webwork

[Harry Kyoshiro]

Hay...


I'm using package com.opensymphony to upload file.
Its work to upload file, but i wonder how i can delete file ?

Ex : i have a simple form
Name : Harry
browse file to upload : test.txt

delete


Name : John
browse file to upload : sample.doc

delete



So.. if i delete Harry, i want delete just Harry's file, not john file.
i put the upload file in C:/temp/upload

i've tried to write code like this
String dirUpload = "C:/temp:upload";
File file = new File(getServletContext.getRealPath(dirUpload));
file.delete();


For your information, i'm using webwork 2.0, jakarta-tomcat4.1.29

Somebody help me please
Thanks
