From the http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html I cant see any place where you can specify a variable for originating method. Also looking through the events log4j passes around it doesnt look like that information gets passed down the chain of events.(http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/spi/LoggingEvent.html).

However if you really need this functionality you could probably pull off some workaround involving implementing your own DataSourceProxyBase. I downloaded the jdbcdslog source from their download page, It looks like you can extend and override some methods from the DataSourceProxyBase class and add in your own logger. Then point your setup to use that data source proxy.

<bean id="dataSourceActual" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName">
        <value>java:comp/env/jdbc/MyDatasource</value>
    </property>
</bean>

<bean id="dataSource" class="com.me.MySoureConnectionPoolDataSourceProxy">
    <property name="targetDSDirect" ref="dataSourceActual" />
</bean>

If you download the source you can start following their program around and see what you would need to override to implement what you need. A good starting place might be the class PooledConnectionLoggingProxy
