I signed my MIDlet App using the following steps !



I am just copying the commands ,


keytool -genkey -alias Huzefa -keyalg RSA -validity 365 -keystore silentmmobile.sks



keytool -export -alias Huzefa -keystore silentmmobile.sks -file silentmmobile.crt



jarsigner -keystore silentmmobile.sks -storepass netpace SilentMMobile.jar Huzefa



java -jar D: oolswkt23 inJadTool.jar -addcert -alias Huzefa -storepass netpace -keystore silentmmobile.sks -inputjad SilentMMobile.jad -outputjad SilentMMobile.jad



java -jar D: oolswkt23 inJadTool.jar -addjarsig -alias Huzefa -jarfile D:HuzefaJ2MEPractiseSilentMMobiledistSilentMMobile.jar -keystore silentmmobile.sks -storepass netpace -keypass netpace -inputjad SilentMMobile.jad -outputjad SilentMMobile.jad








After performing all the above process, I copied the SilentMMobile.jar, SilentMMobile.jad, and silentmmobile.crt in the Mobile Sony Ericcson P990i


Then add the cretificate by clicking on the silentmmobile.crt

Then click on the SilentMMobile.jar


Installation started and at the end of the installation, Error Appeared:
That is

Security Information

Component failed security check Cannot install.



Authentication Failed.




Please any one can tell me the reason


I will be thank full....
