intellij idea - No appenders could be found for logger (org.apache.catalina.core.StandardContext)

Question

I'm getting this error when I changed the data source in my DataSource.groovy. I really have tried most of the tricks that I found in here, but nothing has worked yet. I don't know if anyone can help.

 Error |
    log4j:WARN No appenders could be found for logger (org.apache.catalina.core.StandardContext).
    Error |
    log4j:WARN Please initialize the log4j system properly.
    Error |
    log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
