Re: Exception invoking periodic operation
My advice: Tomcat 5 is alpha. As a newbie, switch to 4.1.24, then see if you have the same problem. John Moraes, Fabio wrote: (I'm not sure if everybody saw this message, so I'm reposting it.

RE: Exception invoking periodic operation
Thanks for the answer. No, I didn't mess with commons-logging.jar or commons-logging-api.jar. I just added mysql-connector-java-3.0.8-stable-bin.jar, but (I THINK) there is no problem with that action. --- Fabio Moraes [EMAIL PROTECTED] System Engineer Work Force Management System +55 21 3088 9548 -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Thursday, July 24, 2003 17:32 To: Tomcat Users List Subject: RE: Exception invoking periodic operation Sensitivity: Private Howdy, >SEVERE: Exception invoking periodic operation: >org.apache.commons.logging.LogConfigurationException: >org.apache.commons.logging.LogConfigurationExc >eption: java.lang.IncompatibleClassChangeError: >org.apache.commons.logging.impl.SimpleLog >at >org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryIm pl.j Did you add/remove/change any files in $CATALINA_HOME/common/lib?
