Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds 的解決方法

錯誤 ：
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. 
也就是我們限定了部署的時間導致的錯誤。

修改 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="1000" 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" 改爲  start-timeout="100" 或者更長，根據不同同學的工程大小來設置。最後重啓eclipse就可以了。
