Tomcat7异常 java.lang.NoClassDefFoundError

下载下来tomcat7.0,解压后，使用时，MyEclipse控制台报异常：

java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:56)
Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory

Exception in thread "main"

解决办法：

window---Myeclipse Enterprise workbench----Servers---tomcat---paths

Prepend to classpath:
点击Add JAR/ZIP 选择tomcat路径bin目录下的tomcat-juli.jar

确定，重启tomcat，OK。
