Issue with reasoner and getting owlready2.base.OwlReadyJavaError

Gopi
Hi,
While running the reasoner we are getting the below error.


raise OwlReadyJavaError("Java error message is:\n%s" % (e.stderr or e.output or b"").decode("utf8"))
owlready2.base.OwlReadyJavaError: Java error message is:
log4j:WARN No appenders could be found for logger (com.hp.hpl.jena.sparql.mgt.ARQMgt).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
