According to JSFC’s configuration guide, the configuration names are case-sensitive (e.g. serverList and username). Therefore, ServerList, UserName, ServiceName, and RetryMillis are not valid from JSFC’s perspective. Especially, ServiceName and RetryMillis do not even exist in the JSFC’s guide at all.

The correct way to set fail-over server in JSFC is that there should be a space character separated between each server name/host name/ip address.

For example,

XConfigDb configDb = new XConfigDb();
...
configDb.addVariable("serverList", "10.42.68.69 localhost 192.168.27.46 192.168.27.48");
...

_session = Session.create(_appId, _configDb);

• 10.43.68.69 is tried first.
• localhost is tried second.
• 192.168.27.46 is tried third.
• 192.168.27.48 is tried last.

Hope this helps.
