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

一、bug:

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

二、原因：

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。

三、解决办法：

修改您的Eclipse的工作目录即：workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml文件。 
<servers> 
<server hostname="localhost" id="JBoss v5.0 at localhost" name="JBoss v5.0 at 
localhost" runtime-id="JBoss v5.0" server-type="org.eclipse.jst.server.generic.jboss5" 
server-type-id="org.eclipse.jst.server.generic.jboss5" start-timeout="100" stop- 
timeout="15" timestamp="0"> 
<map jndiPort="1099" key="generic_server_instance_properties" port="8090" 
serverAddress="127.0.0.1" serverConfig="default"/> 
</server> 
</servers> 
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。
