Just before I got AccuTimeCard working, I was getting an Exception 'Caused by: java.lang.SecurityException: class "org.apache.log4j.Category"'s signer information does not match signer information of other classes in the same package'. The only real difference in my start script and TimeCard.bat was the order of jars in the classpath, so I changed it to match the batfile and it worked. Apparently org.apache.log4j must come before org.apache.commons.logging, or the error is triggered.
