it showing above error.

issue 1: can public key?

i googled it. information there public key not information creating. how can generate application.

issue 2 : if moving application online server (e.g. apache derver) need copy keystore file also>?

1. you need specify same alias jarsigner tool. used 'myself' when building keystore: use again.
2. definitely not. contains private key. keep private.
