7610 Symbian completely solves the problem that jar files cannot be opened or cannot be installed

Solve the small problem about jar files: 1. many of my friends asked me that all jar files could not be opened. The solution is very simple. Go to the E/system/midlets/folder and put the 101 */in it. click "Install once" to install the JAR file ~ After installation, a new E/system/midiets/101 *** folder is generated. You can delete the 101 *** folder that you clicked. jar to install! 2. The downloaded JAR file cannot be installed, and many friends have taken the lattice card for processing, or even have not solved the problem after the lattice machine... In fact, you only need to enter C and E/system/install/Registry/and delete the. reg file (the installation record of the JAR file) in it to install the JAR file normally. 3. A friend asked me. the jar file cannot be opened after it is installed. the name of the JAR file is renamed with a Chinese name. The solution is to change the name to English or a number. jar can be enabled normally after being installed again.
