Java Servlet to Browse to File under Tomcat

I need a Java servlet which will browse to open a file, then read the file. The servlet should work under Tomcat version 6. For the file browse, I want a look and feel similar to what is found at: <[login to view URL]> But the columns should be: Name Size Type Date [link to choose] Once the file is chosen, then it should be read. I am attaching the CSS.
