Use <gateway> together with <annotation-driven>

Hi,

I tried to use both <gateway> and <annotation-driven> element in my config xml, but it keeps giving me the following error:

Code:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'fooService': Post-processing of the FactoryBean's object failed; nested exception is java.lang.IllegalArgumentException: Class must not be null at org.springframework.beans.factory.support.FactoryBeanRegistrySupport$1.run(FactoryBeanRegistrySupport.java:142) at java.security.AccessController.doPrivileged(AccessController.java:215) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:116) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.getObjectFromFactoryBean(FactoryBeanRegistrySupport.java:91) at org.springframework.beans.factory.support.AbstractBeanFactory.getObjectForBeanInstance(AbstractBeanFactory.java:1285) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:217) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:185) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:164) at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:881) at testing.Demo.main(Demo.java:39) Caused by: java.lang.IllegalArgumentException: Class must not be null at org.springframework.util.Assert.notNull(Assert.java:112) at org.springframework.core.annotation.AnnotationUtils.findAnnotation(AnnotationUtils.java:122) at org.springframework.integration.config.MessageEndpointAnnotationPostProcessor.postProcessAfterInitialization(MessageEndpointAnnotationPostProcessor.java:111) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization(AbstractAutowireCapableBeanFactory.java:361) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.postProcessObjectFromFactoryBean(AbstractAutowireCapableBeanFactory.java:1427) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport$1.run(FactoryBeanRegistrySupport.java:139) ... 9 more

Here is my config xml:

Code:

<?xml version="1.0" encoding="UTF-8"?> <beans:beans .....> <message-bus /> <annotation-driven /> <channel id="input" /> <channel id="output" /> <gateway id="fooService" service-interface="testing.FooService" request-channel="input" reply-channel="output" /> <handler-endpoint input-channel="input" output-channel="output" handler="myHandler" /> <beans:bean id="myHandler" class="testing.MyHandler" /> </beans:beans>

I found that if I remove the <annotation-driven> element, everything would be fine. Is it a bug or my config problem ?

Many Thanks,
