Hi, Thanks to reply! Can you tell me how to try to fix the problem? I have reinstall the apache-tomcat-7.0.28.exe, but the problem is still there. The log is the same as before: 2012-07-12 19:25:48 Commons Daemon procrun stderr initialized java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:60) Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory at java.net.URLClassLoader$1.run(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 1 more Exception in thread "main"

Hi, This error can be appeared when that class is seen at compile time and not in run time or if u add and remove relevant jar file more than one time.then there can be a possibility that at run time it picks a class which was not picked at compile time.
