getting full path from html:file

[john mattucci]

I have the following
<html:form action="HtmlFile.do" enctype="multipart/form-data">
Please select the file that you would like to upload:<br />
<html:file property="file" /><br /><br />

<html:submit />
</html:form>
Once the user selects a file, in the textbox the full path of the file is shown. I was wondering how can one obtain this value after the user has hit submit?
Thank you all for your time
