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.ProxoolDriver] [Problem]
org.logicalcobwebs.proxool.ProxoolException: Attempt to refer to a unregistered pool by its alias 'ums'
 at org.logicalcobwebs.proxool.ConnectionPoolDefinition.doChange(ConnectionPoolDefinition.java:246)
 at org.logicalcobwebs.proxool.ConnectionPoolDefinition.<init>(ConnectionPoolDefinition.java:143)
 at org.logicalcobwebs.proxool.ProxoolFacade.registerConnectionPool(ProxoolFacade.java:96)

 at java.sql.DriverManager.getConnection(DriverManager.java:582)
 at java.sql.DriverManager.getConnection(DriverManager.java:154)

 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>
