Hi. I'm running application that includes log4j weblogic 6.1 and struts 1.1 ( with common-logging.jar , common-beanutils.jar ...all of common's jars.) And I'm getting this exception : " Exception thrown while loading epv-web: org.apache.commons.logging.LogConfigurationException: java.lang.reflect.InvocationTargetException> org.apache.commons.logging.LogConfigurationException: java.lang.reflect.InvocationTargetException at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.ja va:494) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.ja va:285) ...etc" I need log4j, so I can't remove it from my classpath. How can I tell common-logging to use other logger than log4j, I think this is all about. Or if there's any other way to go around this problem. Thanx. Arik.
