Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds

错误 ：
Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor. 
也就是我们限定了部署的时间导致的错误。

修改 workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml文件。 
 
server-type-id="org.eclipse.jst.server.generic.jboss5" start-timeout="1000" stop- 
timeout="15" timestamp="0"> 
 
 
把 其中的start-timeout="45" 改为  start-timeout="100" 或者更长，根据不同同学的工程大小来设置。最后重启eclipse就可以了。
