Cacerts default password?

    Hi everybody,

    I have a question relative to the default java keystore,the cacerts. I'm trying to import/export certificates but i'm prompted for the keystore's password.I just installed jdk and i'm wasn't prompted for any such password. Is there a default password? anyones knows it or is there a way may be to change it to something new,which i'll know, without being prompted for the old?
