//数据源配置1
<bean id="dataSource2"
    class="org.springframework.jndi.JndiObjectFactoryBean">
   <property name="jndiName" value="jndiName" />
</bean>
或者加上
xmlns:jee="http://www.springframework.org/schema/jee"
http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd
用<jee:jndi-lookup id="dataSource" jndi-name="jndiName"/>
注意：在jboss4中对3.0支持有限此法有bug jboss5支持ok

//数据源配置2
  <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
  <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
  <property name="url" value="jdbc:oracle:thin:@rj-t42:1521:elvis"/>
  <property name="username" value="scott"/>
  <property name="password" value="tiger"/>
