Java™
The menu displayed allows you to increase or decrease 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, mobile phone asks you to confirm your increased risk exposure.
The maximum risk exposure increase is limited by the security status. Depending of the manufacturing configuration, it means, for example, that "Net Access" security group authorization cannot be set to a permissive value higher that "Session" for an "uncertified" MIDlet ("Single confirmation" and "Always" are unavailable in the security configuration menu) but an operator "certified" MIDlet may have all permission values available without any limitations.
What is Java™?
Java™ is a new technology enabling use of powerful applications in the mobile phone area. Business applications and games are easily downloadable by the
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,
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 of 2 files:
•The JAD file
•The JAR file
JAD file stands for Java™ Application Descriptor. It is a small file describing the content of a JAR file (version, vendor name, size…) and displayed by the mobile phone. JAD file size is usually less than 2
JAR file stands for Java™ Archive. It refers to the application data themselves (program, images, sound). A JAR file may be up to 200
NOTE: 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.
