Java™ is a new technology
enabling use of powerful
applications in the mobile phone
area. Business applications and
games are easily downloadable by
the end-user on a Java™ featured
handset.
Your mobile phone is a MIDP 2.0
compliant Java™ platform which
implements WMA (SMS support)
and MMAPI (Multimedia support)
options, providing an exciting
environment to run highly graphical,
networked and intuitive MIDP
applications.
Such applications may be, for example, a wide range of
games and appealing applications like action and logic
games, agenda, e-Mail reader, Web browser…

A Java™ application or a game designed to run in a mobile
phone is named a MIDlet (MIDP applet).
A MIDlet is usually made of 2 files:
- The JAD file
- The JAR file
JAD file stands for P ava™ pplication 7 escriptor. It is a
small file describing the content of a JAR file (version,
vendor name, size…) and displayed by the mobile phone.

JAR file stands for Java™ Archive. It refers to the
application data themselves (program, images, sound).
P ) 44+ >
In rare circumstances, MIDlet vendors may provide
no JAD file and the MIDlet is the JAR file alone. In such a
case it is your only responsibility to evaluate the risk to
download the JAR file without possibility of consulting the
JAD file.

MIDlets are easily downloaded in the mobile phone through
the Games or Applications menus or through the WAP
browser.
In almost all cases, you will first receive a JAD file which will
be displayed on the screen.
Much care must be given in examining the content of the file
as explained further.
When you select a JAD file, your mobile phone downloads
it, displays data contained and prompts you to acknowledge
the JAR file download.
The popup displays information below:
- Name of the MIDlet
- Version
- Size (JAR file size)
- Vendor name
- Security status ( (0#"" see "Security
considerations" paragraph below)
- JAR file URL.
If you do not want to download the main data (JAR file), you
shall refuse to acknowledge further airtime consumption by
selecting "Cancel" (JAR file is not downloaded).
If you agree on the MIDlet installation, just select "Ok". The
MIDlet is installed with security levels set to default values
associated with its security status.
