解决方法

到网上搜索了一下，比较好解决，有个网址http://mianniu.com/programming-world/java-lang-noclassdeffounderror-orgapachejulilogginglogfactory-at-org-apache-catalina-startup-bootstrap上说

Solutions

1. In Eclipse, Open the “Server” tab.
2. Double click on the “Tomcat6″ entry to see the configuration.
3. Then click on the “Open launch configuration” link in the “General information” block.
4. In the dialog, select the “Classpath” tab.
5. Click the “Add external jar” button.
6. Select the file “/usr/share/tomcat6/bin/tomcat-juli.jar”
7. Close the dialog.
8. Start tomcat 6 from Eclipse.

实际上，就是把bin/tomcat-juli.jar 下add tomcat classpath下，效果如下：

重新启动Tomcat7.0，发现启动成功。
