Java TV - Where can i use the file:// url

i am new to DTV and here is a very basic doubt abt file:// url.Under what all situations can we use a file://i had seen at many places that restrictions can be there depending upon whether the file is local or in the broadcast file system.

Don't use the "file://" URL.

If you want to address files which are part of an application, either address them by opening a file or via a resource. For example, a file called "example.xml" in the base directory of an application can be accessed by either

a) new FileInputStream("example.xml")

b) put the directory containing the file in the application's classpath and then access the file by Class.getResource("example.xml")

The "file://" URL was invented before MHP. Some URL is needed as the return type of methods like Class.getResource().
