org.logicalcobwebs.proxool.ProxoolException: Attempt to refer to a unregistered
Spring3 下使用proxool做连接池的时候出现异常ERROR 2010-07-06 12:27:10,328
org.logicalcobwebs.proxool.ProxoolException: Attempt to refer to a unregistered pool by its alias 'ums'

原因：
org.springframework.web.context.ContextLoaderListener 加载先于proxool
解决办法：将proxool 也改成listener加载并先于spring
由于proxool 还没有listener的实现，所以自己写了一个以listener方式加载proxool 的实现的补丁proxool-listenerCfg.jar
下载补丁修改web.xml
<servlet> <servlet-name>ServletConfigurator</servlet-name> <servlet-class> org.logicalcobwebs.proxool.configuration.ServletConfigurator </servlet-class> <init-param> <param-name>xmlFile</param-name> <param-value>WEB-INF/proxool.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> 改为:
<context-param><param-name>proxoolConfigLocation</param-name><param-value>WEB-INF/proxool.xml</param-value></context-param><listener><listener-class>org.logicalcobwebs.proxool.configuration.ListenerConfigurator</listener-class></listener><listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>
