After not having used my rosjava nodes for a year or so I am now getting this error when I run a node,
> log4j:WARN No appenders could be found for logger (org.ros.internal.node.client.Registrar).
> log4j:WARN Please initialize the log4j system properly.
> log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
I have searched fro a resolution but can't find one. Manually configuring a properties file doesn't help.
Any idea why I am getting this error?
