I am using Sprring 2.0 with Jboss 4.0.5. Today when I turned on the log to debug level, I saw that it is continuously trying to open and close the socket even when there are no messages in the queue, and is throwing Exception in the process. I guess the opening and closing of socket is due to the way Listeners are implemented. Everything is working as expected except the Exceptions.

I am using DefaultMessageListenerContainer and haven't defined any transaction.

<bean id="testContainer" class="org.springframework.jms.listener.DefaultMes sageListenerContainer">
<property name="connectionFactory" ref="testFactory" />
<property name="destination" ref="queueTest" />
<property name="messageListener" ref="testListener"/>
</bean>

<bean id="testFactory" class="org.springframework.jndi.JndiObjectFactoryB ean">
<property name="jndiName" value="UIL2ConnectionFactory"/>
</bean>


I have pasted the error below:
