NullPointerException when using keytool


I’'ve setup a wildfire server and am trying to exchange the ssl-Key with the help of the SSL-Guide (http://www.jivesoftware.org/builds/wildfire/docs/latest/documentation/ssl-guide. html).

My Problem is that everytime I try to change anything in the keystore (for example keytool -keystore keystore -storepasswd) I get the following output:

Enter keystore password:

keytool error: java.lang.NullPointerException

On the other hand I can list and export the existing certificates and can add certificates with the Wildfire Admin Console, but I want to import a key and I havn’'t seen any Option there.

Could anyone help me?


I’'ve solved the problem. The confusing fact of getting the Exception was caused by an empty password.

The default password in changeit[/b] and not an empty one.
