tomcat Could not find or load main class

 在官网下载apache-tomcat-7.0.包：（1）当从下“Source Code Distributions”载包时，会遇到在bin目录下找不到的问题，“”后显示

[root@ncut apache-tomcat-7.0.22]# bin/
Using CATALINA_BASE:   /home/ncut/software/apache-tomcat-7.0.22
Using CATALINA_HOME:   /home/ncut/software/apache-tomcat-7.0.22
Using CATALINA_TMPDIR: /home/ncut/software/apache-tomcat-7.0.22/temp
Using JRE_HOME:        /usr/java/jdk1.6.0_26
Using CLASSPATH:       /home/ncut/software/apache-tomcat-7.0.22/bin/:/home/ncut/software/apache-tomcat-7.0.22/bin/

但是 ps -ef | grep tomcat  并没有启动.

（2）应该从“Binary Distributions“的下载core包，重新解压启动，查看端口和在浏览器输入http://localhost:8080/一切正常。

总结：下载安装包要正确。
