MIME media type name : Text

MIME subtype name : Vendor Tree - vnd.sun.j2me.app-descriptor
 
Required parameters : None
 
Optional parameters : charset
The Java(TM) 2 Platform, Micro Edition(J2ME) application descriptor
file conforms to the usage of the optional charset parameter for
text/plain in rfc2046.  Since the file contains text used by Java
applications it is expected that most application descriptor files
will be delivered as UTF-8.  The default charset is UTF-8.

Encoding considerations : The content of this type consists of 8bit 
text, which must be encoded when used on transports incapable of 
supporting 8bit.
 
Security considerations :
 
The MIDP application descriptor contains attribute information used by
application management software. The descriptor file references a
downloadable Jar file. The Jar file may be signed. The Java class
files within the Jar file must be preverified before they can be run
on the J2ME KVM.  A network operator may require the descriptor
file and associated Jar file to be delivered from the same source and
delivered over a secure network connection.
 
Interoperability considerations : None

Published specification :
Java Community Process -
Mobile Information Device Profile (MIDP) Specification.

Applications which use this media :
 
J2ME application management software runs on pagers and cellphones
that are enbled with a Java Virtual Machine(JVM) execution
environment. The application descriptor provides the information
needed to download and install a Java application and the runtime
parameters needed by the application.
