今天，安装Tomcat7.0.21后，单独用D:\apache-tomcat-7.0.21\bin\startup.bat启动web服务正常。但在MyEclipse8.5中集成配置Tomcat7后，在MyEclipse启动Tomcat服务则出现如下错误提示： 
Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
at org.apache.catalina.startup.Bootstrap.(Bootstrap.java:54) 
Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory

… 1 more 
Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit. 
二、解决办法： 
通过如下操作，问题解决：MyEclipse->Window->Preferences->MyEclipse->Servers->Tomcat->Tomcat 6.x->Laucch->Create Launch Configuration->Classpath->Bootstrap Entities->Add External JARs->选择并填加D:\apache-tomcat-7.0.21\bin\tomcat-juli.jar就OK啦！
