启动tomcat时Unable to connect to any hosts due to exception,该如何处理

启动tomcat时Unable to connect to any hosts due to exception
启动tomcat时总有Unable   to   connect   to   any   hosts   due   to   exception错误，本工程没有连接数据库。
出现了下面的错误：
2007-6-1   20:00:33   org.logicalcobwebs.proxool.Prototyper   sweep
严重:   Prototype
java.sql.SQLException:   Unable   to   connect   to   any   hosts   due   to   exception:   java.net.ConnectException:   Connection   refused:   connect

没有连接数据库的代码。
那位知道的望解答下，谢谢。
