To replace your current log4j jar file with the new one, do the following: 

On Tomcat:

1. Download the patched jar file: log4j-1.2.17-NoJMS-2.jar
2. Remove the current log4j jar file from the /TOMCAT_HOME/webapps/ceg4.4/WEB-INF/lib/ sub-directory. The file will be named log4j-1.2.12.jar.
3. Copy the patched jar file into the Transferology Connector install under the sub-directory /TOMCAT_HOME/webapps/ceg4.4/WEB-INF/lib/.
4. Review your /TOMCAT_HOME/webapps/ceg4.4/WEB-INF/classes/log4j.properties file to confirm the JMS Appender is not configured.
5. Restart Tomcat.
