trust the server's certificate

hello

I have a certificate already generate by the server and I do not know its alias, how I can make:

- to export the server certificate from the certs keystore.

with keytool:

keytool -export -keystore "java.home"/lib/security/cacerts -alias jamie -file server.cer

but I had the error: alias does not exist.

somebody will be able to give me an indication thank you .
