I am trying to use keytool to get self-signed certificate. I have followed the process to the second step in the documentation. Since step 3,4 and 5 are optional, I leave them out. However when I try to start the server, it is giving me an error “Error starting SSL XMPP listener on port 5223: null” I am running 2.2 on windows XP with java 1.5.05. I have disabled the windows built in firewall and the problem still persist.
