Eclipse+Tomcat配置错误：java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory

出现错误如图：

java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
	at org.apache.catalina.startup.Bootstrap.(Bootstrap.java:55)
Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory

解决方法：

点击windows→Perferences

如图，将tomcat  bin目录下的tomcat-juli.jar文件加入到tomcat  运行的classpath中

进行测试，一切正常啦：
