NoSuchMethodException error occuring when enabling listener to conumer messages

[catDeveloper]

I am writing an application to enable/disable listeners. The application is being deployed on tomat. Upon deploying the application I am seeing the error below occur.


[SimpleAsyncTaskExecutor-1] WARN 16:47:00,337 AbstractMessageListenerContainer.invokeErrorHandle r(178) - Execution of Rabbit message listener failed, and no ErrorHandler has been set.

Below is my configuration for the listener.

<bean id="connectionFactory" class="org.springframework.amqp.rabbit.connection.SingleC onnectionFactory">
<constructor-arg value="localhost"/>
<property name="username" value="guest"/>
<property name="password" value="guest"/>
</bean>

<bean id="messageListenerContainer" class="org.springframework.amqp.rabbit.listener.SimpleMes sageListenerContainer">
<property name="connectionFactory" ref="connectionFactory" />
<property name="queueName" value="cbs.push.queue"/>
<property name="concurrentConsumers" value="1" />
<property name="messageListener" ref="messageListenerAdapter" />

</bean>

<bean id="messageListenerAdapter" class="org.springframework.amqp.rabbit.listener.adapter.M essageListenerAdapter">
<property name="delegate" value="com.catmktg.digitalgateway.consumer.asynch.Message Handler" />

</bean>

Here is my implementation for the message handler.



import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.amqp.core.Message;

public class MessageHandler {

public void handleMessage(String text) {

try {
log.debug("************* Received CBS Msg. [" + text+ "]************************");

} catch (Exception e) {
log.debug("************* Error - handleMessage(String text)");
e.printStackTrace();
}

}
}

There's no bean definition for your handler, so Spring thinks it's a String:



value="com.catmktg.digitalgateway.consumer.asynch.Message Handler"


should be a ref= to another bean definition, or a nested inner <bean/> element.

I feel like an idiot for missing that. Thank you sooooooooo much for responding.

I would send you a box of choclates if i could
