When I run the project, there are always appearing the warn information:
log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

I have put the log4j.properties to the WEB-INF/ derictory, but the warnings still exist. Can anyone tell me where to put the log4j.properties to avoid the annoying warning? ^_^

Here is my configuration which is placing the log4j.xml in the WEB-INF dir and using Spring to load up the configuration during startup.

spring-context.xml:

	</bean>
</beans>

web.xml:

	<!-- Spring -->

	<context-param>

Make sure you download the apache commons-logging.jar, spring jars, and log4j jar

I don't have spring.xml or hibernate.xml or some files like this, I just have applicationContext.xml, web.xml and zk.xml configuration file. Is it right to integrate with hibernate and spring ? I don't know why I can not create session.

Seems that the org.apache.commons.dbcp.BasicDataSource needs additional jars.

If you work with spring. Why not use the spring classes for the dataSource ?


!!!! Code not tested !!!!

<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">

		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/deri" />
		<property name="username" value="root" />
		<property name="password" value="deri" />
	</bean>
