VCO Plugin SolarSystem log messages

Hi,

I want to understand how plugin works. I have put few log messages in createPluginFactory.function of SolarSystemAdapter class. The plugin is deployed fine. Where are these log messages? I have tried different variations but none of them are getting logged in any log files under C:\Program Files\VMware\Orchestrator\app-server\logs

log.info("info:createPluginFactory");

log.debug("debug:createPluginFactory");

log.warn("warn:createPluginFactory");

log.error("error:createPluginFactory");

System.out("createPluginFactory");

Thanks,
