Unable to access certificate store

I have a xmpp server (openfire 3.9.3) and trying to secure my non-ssl connection to ssl connection.

That's why i have created a self-signed certificate using java keytool as:

keytool -genkey -keystore keystore -alias example.com

and i filled the several pieces of information required for the certificate.

The certificate successfully created. I configured my server to access the keystore file but when restart my xmpp server it says

Unable to access certificate store. The keystore may be corrupt

what should i do to fix this?

You can :

1. Delete certs in AdminWEB interface.
2. Restart openfire
3. Delete /opt/openfire/resources/security/keystore file
4. Generate new cert from web interface.
