11.5.4Sign a MIDlet

Use the tool “jadtool.jar” to sign a Java MIDlet. This program is in the folder “wkt\bin”.

java -jar jadtool.jar -addjarsig -jarfile helloworld.jar -inputjad helloworld.jad -outputjad helloworld.jad

-alias keyname -storepass keystorepassword -keypass keypassword -keystore customer.ks -encoding UTF-8

11.6Attention

The central element of Java Security is the private key. If Java Security is activated and you lose the private key, then the module is destroyed. You do not have a possibility of deactivating Java Security, downloading of a new Midlet or of starting any other operation concerning Java Security.

In order to prevent this, we recommend to you particularly to secure the private key.
