Spring监听器与proxool.xml（数据库连接池）

Spring监听器

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 org.logicalcobwebs.proxool.ProxoolDriver.connect(ProxoolDriver.java:77) at java.sql.DriverManager.getConnection(DriverManager.java:582) at java.sql.DriverManager.getConnection(DriverManager.java:154)

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

点击下载  proxool-listenerCfg.jar 

Xml代码 

<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>    

 Web.xml配置改为:
