Populate a drop down list with directory contents

[admin]

At the moment i have a static drop down list which consists of a number of options and their associated values. However I want the menu to contain links to the entire contents of a specific directory on my server (c:\stylesheets). I cannot simply hard code the drop down list as the client has the option to upload additional files to the same directory. Does anyone have any suggestions on how I would achieve this? I am using JSP, Java and Javascript.

<form action="dummy" method="post" name="choiceform">

<option value>CHOOSE A STYLESHEET</option>
