启动tomcat时报错Server Tomcat v6.0 Server at localhost was unable to start within 45

在tomcat里加载一个web项目，在启动tomcat时出现了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.这种错误，原因是因为tomcat的启动时间过短了，解决这种错误的方法是：

修改 eclipse工作空间下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 start-timeout="45" 改为 start-timeout="1000" 或者更长，最后再重启eclipse就可以了。
