Exception in thread "main" java.lang.NoClassDefFoundError during starting your Tomcat

If you are using Tomcat v.6 or v.7, you probably get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:54) Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:323) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:268) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:336) ... 1 more Could not find the main class: org.apache.catalina.startup.Bootstrap.
