How can I open local files with link to access local files with jsp

How can I open local files with link to access local files with jsp

I developed an web application using struts 1.2 , I need to display files
within my local system(C:\Testing) in a link format.When user clicks on a
file name it automatically opens(no download option).File can be of any
type(pdf,excel,.doc...) I tried
<LI><A HREF="file:<%=filePath%>"><%=fileName%></A></LI>
or
<LI><A HREF="file:///<%=filePath%>"><%=fileName%></A></LI>
None of them worked..Any kind of help would be really appreciated. Thanks
