Change SSL Certificat used by the application server RSA L&G

Hi all,

I want change the default ssl certificat used by RSA, i have just a certificate (.cer) delivered by my CA.

I deleted the old certificate from the keystore:

keytool -delete -alias server -storepass Av3k5a15num83r0n3 -keystore aveksa.keystore

And i imported my new certificate:

keytool -import -v -noprompt -trustcacerts -alias server -file dev-iag.cer -storepass Av3k5a15num83r0n3 -keystore aveksa.keystore

but when i restarted the server, i ould not access anymore to my UI

I want know if i need to a private key associated to the certificate and an CA root certificate?

Regards.
