Tomcat中的Java JNDI:全局资源上的BeanCreationException/NamingException。查找全局资源返回的同一类

c3p0 jndi tomcat7 spring java

我不明白是什么导致Bean创建异常代表返回所需的相同类。

课程是 com.mchange.v2.c3p0.ComboPooledDataSource ,错误显示预计回来的实例[ 通用域名格式。McChange。v2.c3p0。组合池数据源 ]但是返回的实例[ 通用域名格式。McChange。v2.c3p0。组合池数据源 ]

这是错误:

org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'dataSourceGCA' defined in class path resource [META-INF/xxxxx-security-app.xml]: 
Invocation of init method failed; nested exception is javax.naming.NamingException: 
The local resource link [dataSourceGCA2] that refers to global resource [jdbc/dataSourceGCA2Global] was expected to return an instance of [com.mchange.v2.c3p0.ComboPooledDataSource] but returned an instance of [com.mchange.v2.c3p0.ComboPooledDataSource]

我正在使用Java 7和Tomcat 7。

这是数据源的配置:

在里面 上下文xml :

<ResourceLink name="jdbc/dataSourceGCA2"
  global="jdbc/dataSourceGCA2Global"
  auth="Container"
  type="com.mchange.v2.c3p0.ComboPooledDataSource" />

在里面 服务器xml :

<Resource description="whatever"
  name="jdbc/dataSourceGCA2Global"
  auth="Container"
  factory="org.apache.naming.factory.BeanFactory"
  type="com.mchange.v2.c3p0.ComboPooledDataSource"
  user="xxxxxxxx"
  password="xxxxxxxx"
  initialPoolSize="1"
  minPoolSize="1"
  maxPoolSize="5"
  acquireIncrement="1"
  driverClass="oracle.jdbc.driver.OracleDriver"
  jdbcUrl="jdbc:oracle:thin:@tprodva2:1522/BD2"
  testConnectionOnCheckin="true"
  idleConnectionTestPeriod="300"
  maxIdleTimeExcessConnections="0"
  maxIdleTime="0" />

是什么导致这种行为?

非常感谢您的帮助。
