Application Resource Files
MIDP provides the capability of storing resources in the application's JAR that can be accessed
by a MIDlet at run time. An example of such a resource might be a locale bundle,
an icon, or a graphical image; however, any thing
that can be accessed as an InputStream can also be stored. These
resources are accessed using the method getResourceAsStream(String name) of class
java.lang.Class.
The rules and the parameter string format for accessing
resources inside a JAR file have been discussed in Section 19.1.4, "MIDlet
Suite Execution Environment." As a general rule, if the parameter string to the
getResourceAsStream method begins with a '/', the search for the
resource begins at the "root" of the JAR file; however, if it does not begin
with a '/', the resource is searched for along a path relative to the class
instance retrieving the resource.
