以上错误循环了好几次 正常的访问没有问题，可是每次启动时就出现，整个项目原来是好的自己导入就出现了…… 请高手给点建议

看看是否连接数据库错误。

[john25308771026]

数据可没有连接错误 我访问项目的地址可以访问的
<property name="connection.url">jdbc:mysql://192.168.200.100:3306/dzswrmbcs</property>
<property name="connection.username">kaifa</property>
<property name="connection.password">rmsdec2011</property>

很可能是你项目种有做2个连接池的方法 ，一个可能是读配置上的，在报空的时候dwr在项目中做init 连接池方法，就有这种可能

这是我的配置文件 要是楼上的那种情况 怎样解决掉……

可以看提示啊
问题未必是我那样的
提示 连接超时 错误在socketConnect
说明在你启动tomcat 的时候，socket 的连接超时，这个可能跟你的项目无关，是tomcat的问题
