Name : Gary Adams E-mail : gary.adams&sun.com 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. http://java.sun.com/jcp/jsr/jsr_037_mid.html 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. Additional information : 1. Magic number(s) : None 2. File extension(s) : jad 3. Macintosh file type code : Person to contact for further information : 1. Name : Gary Adams 2. E-mail : gary.adams&sun.com 3.
