What's the simplest way to see if a file exists on the server in JSP?

If possible, I'd like the the equivalent of:

<%
    if(FunctionThatTellsMeFileExists("images/001.png")) {
        out.println("YES");
    }
    else {
        out.println("NO");
    }
%>

You might want to try:
if ( new java.io.File("C:\test.txt").exists() ) ...
