Clear text while using File Upload in Struts2

[Mageshwaran]

Hi All,
       In my jsp code i had used "<s:file name="uploadFile" 
label="File" size="20" onkeypress = "killEvent(event)"/>" for file 
upload using IFrame.

The issue is if i select a file using file dialog, there is no option to 
clear the selected text. Can any one help me how to clear the uploaded 
file path text?

Thanks in Advance,
Magesh.
