The source.jsp file, distributed with Apache Tomcat server, will

information such as the web root path and directory listings could
be obtained.

Example: http://target/examples/jsp/source.jsp?? - reveals the web root
         http://target/examples/jsp/source.jsp?/jsp/ - reveals the contents of the jsp directory

Solution: Remove default files from the web server
