Java™ 83
If you do not want to enter the security menu, simply select the
"Back" button. You can proceed by selecting " OK " button.
The menu displayed allows you to increase or decrease the
permissions currently applied to the current MIDlet for each of
the security groups.
When you set a more permissive authorization to a security
group than the current value, the mobile phone asks you to
confirm your increased risk exposure.
The maximum risk exposure increase is limited by the security
status.
What is Java™?
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.
What is a MIDlet?
A Java™ application or a game designed to run in a mobile
phone is named a MIDlet (MIDP applet).
A MIDlet is usually made up of 2 files:
- The JAD file
- The JAR file
JAD file stands for
J ava™ A pplication D escriptor. It is a small
file describing the content of a JAR file.
JAR file stands for
J ava™ A rchive. It refers to the application
data themselves (program, images, sound). A JAR file can have
a size of up to 200 KB.
Note: In rare circumstances, MIDlet vendors may provide no
JAD file and the MIDlet is just the JAR file. In such a case it is
your sole responsibility to assess the risk of downloading the
JAR file without any possibility of consulting the JAD file.
