log4j and websphere 6.1 configuration

How to configure log4j for websphere 6.1 as my jsp code contains display tag, even though i have added the log4j jars in the WEB-INF/lib folder it shows the below error on the console whenever trying to view the page through the WAS server.

 S开发者_如何学运维ystemErr     R log4j:WARN No appenders could be found for logger (org.displaytag.properties.TableProperties).
 SystemErr     R log4j:WARN Please initialize the log4j system properly.

the message is just a notification that log4j hasn't been configured to log messages from org.displaytag.properties.TableProperties class (if any)..

this is not an issue as such.. usually this can be ignored.

seems like you're missing the log4j.properties. Put that file in your classpath

@ananth No it cant be ignored what if the display tag doesnt have any effect while viewing the page i suggest the log4j properties file should be added
