我最近需要在MyEclipse中使用Tomcat7，已經在Servers中配置了本地的Tomcat路徑，之后發布項，在MyEclipse啟動Tomcat服務則出現如下錯誤提示：

Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactoryat org.apache.catalina.startup.Bootstrap.(Bootstrap.java:54) Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.accessController.doPRivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:323) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:268) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:336) … 1 more Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit.

單獨用D:/WorkSoft/apache-tomcat-7.0.62/bin/startup.bat啟動web服務正常。

解決辦法： 通過如下操作，問題解決：MyEclipse->Window->Preferences->MyEclipse->Servers->Tomcat->Tomcat 6.x->Laucch->Create Launch Configuration->Classpath->Bootstrap Entities->Add External JARs->選擇并填加D:/WorkSoft/apache-tomcat-7.0.62/bin/tomcat-jjar就OK，截圖如下：
