Exception in thread “main” java.lang.NoClassDefFoundError org/apache/commons/logging/LogFactory

今天让做jxfp项目，用的myeclipse8.5+tomcat7,启动的时候报错：

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 

是缺少tomcat-juli.jar，于是引入，但还是不行，最后用这个解决了：

MyEclipse->Window->Preferences->MyEclipse->Servers->Tomcat->Tomcat 6.x->Laucch->Create Launch Configuration->Classpath->Bootstrap Entities->Add External JARs->选择并填加H:\apache-tomcat-7.0.21\bin\tomcat-juli.jar就OK啦！

 

如果还有问题，将Java EE 5 Libraries删掉再加进来试试。。。。。。。
