How to clear MQ channel with lingo

[markg]

Hello,

I am making asynchronous calls via Lingo using lingo-1.0-SNAPSHOT.jar in the application run on Tomcat.

<bean id="stagingManagerServer"
class="org.logicblaze.lingo.jms.JmsServiceExporter ">
<property name="service">
<ref bean="stagingManagerService" />
</property>
<property name="serviceInterface"
value="org.tiaa.scm.tool.service.IStagingManager" />
<property name="connectionFactory">
<ref bean="jmsQueueConnectionFactory" />
</property>
<property name="destination">
<ref bean="jmsDestination"/>
</property>
</bean>

<bean id="stagingManagerClient"
class="org.logicblaze.lingo.jms.JmsProxyFactoryBea n">
<property name="serviceInterface"
value="org.tiaa.scm.tool.service.IStagingManager" />
<property name="connectionFactory">
<ref bean="jmsQueueConnectionFactory" />
</property>
<property name="destination">
<ref bean="jmsDestination"/>
</property>
<property name="remoteInvocationFactory" ref="invocationFactory" />
</bean>

<bean id="invocationFactory"
class="org.logicblaze.lingo.LingoRemoteInvocationF actory">
<constructor-arg>
<bean class="org.logicblaze.lingo.SimpleMetadataStrategy ">
<property name="oneWayForVoidMethods" value="true" />
</bean>
</constructor-arg>
</bean>

My problem is that lingo does not appear to be clearing MQ channel after asynchronous call is made. Therefore after some time I have too many channels open and asynchronous calls fail.

How do I setup my asynchronous calls so that the channel would automatically clear after each call?

Also, when the container is bounced lingo does not always close open MQ queue and does not delete temporary queue (see exceptions attached).

Any clues would be greatly appreciated.

Thanks,
Mark
