启动Tomcat7.0时 提示:could not find the main class……

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，从新启动tomcat7.0能够启动了！
