Eclipse运行出现“A Java Exception has occured”
具体的报错信息为：
Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory
at org.apache.catalina.util.LifecycleBase.(LifecycleBase.java:39)
Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory

今天只是想运行下以前的程序，结果main函数报错，弄了半天也没弄好，最终发现问题非常简单：
只要右击项目 -> Run As -> Java Application 即可
因为之前运行过web project，系统默认为Run As -> Server，只要改过来即可。
是不是发现很傻……
