Create self signed key pair and add to new key store:
	keytool -genkey -alias mykey -keyalg RSA -keystore keystore.jks -keysize 2048
	
Export public key and import into new trust store:
	keytool -keystore keystore.jks -export -alias mykey -file my.cer
	keytool -import -alias mypub -file my.cer -keystore truststore.jks
	
(Alternate way) Manually import certificate from HTTPS server to trust store:
        Firefox: Add Exception -> Get Certificat -> View -> Details -> Export as "a.der"
        keytool -importcert -keystore truststore.jks -file a.der
