reconnect to MQ Queuemanager?

[glote]

Hi,

We have a jmstemplate that post messages to MQ, but sometimes we loose contact with the MQ Queuemanger and after that every sends fails...

Is there a way to reconnect/reinitialize the connectionfactories in spring?

Here's our the relevant parts of our config:
<bean id="MQConnectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory">
<property name="hostName" value="${websphere.mq.host}" />
<property name="port" value="${websphere.mq.port}" />
<property name="channel" value="${websphere.mq.channel}" />
<property name="queueManager" value="${websphere.mq.qmanager}" />
<property name="transportType" value="${websphere.mq.transport}" />
</bean>

<bean id="mq-jms-connection-factory" class="org.springframework.jms.connection.CachingC onnectionFactory">
<property name="targetConnectionFactory" ref="jmsQueueConnectionFactory" />
</bean>

<bean id="jmsQueueConnectionFactory" class="org.springframework.jms.connection.UserCred entialsConnectionFactoryAdapter">
<property name="targetConnectionFactory" ref="MQConnectionFactory" />
<property name="username" value="${websphere.mq.user}" />
<property name="password" value="${websphere.mq.pwd}" />
</bean>

<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory" ref="mq-jms-connection-factory" />
<property name="messageConverter" ref="lbsMessageConverter" />
</bean>

<bean id="klientForesporselJmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory" ref="mq-jms-connection-factory" />
<property name="messageConverter" ref="klientMessageConverter" />
</bean>

We are experiencing this same issue. Actually to be exact it seems that sometimes when an mq queue becomes unable, the connection IS re-established, but other times it is not. it seems that when the entire queuemanager is bounced the connection is re-established but when the manager is bounced by operations with a nightly script (haven't root-caused the difference) we do NOT reconnect.

ARe others experiencing this? Is there some configuration we can change?

We are using jmstempate for sending like this:

//snippets

// spring bean.. see below config
public class JmsDistributionPoint implements DistributionPoint {

private final JmsTemplate jmsTemplate;
private final String queueName;

 @Override
   public void send(final Message outboundMessage)  {
      final String messageXml = converter.getConvertedPayload(outboundMessage);
      jmsTemplate.send(queueName,
         new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {
               TextMessage message = session.createTextMessage();
               return makeTextMessage(message , outboundMessage, messageXml);
            }
         });
   }

application-context:

// NB: 'xxx' simply obscuring company details

<bean id="xxx_DP_ONE" class="com.[xxx].model.configuration.distribution.JmsDistributionPoint">
      <constructor-arg value="${xxx.queue.name}"/>
      <constructor-arg ref ="xxxConnectionFactory"/>
   </bean>
<bean id="[xxx]ConnectionFactory" 
      class="org.springframework.jms.connection.CachingConnectionFactory"> 
      <property name="targetConnectionFactory" ref="xxxConnectionFactoryImpl"/> 
      <property name="sessionCacheSize" value="1"/> 
   </bean> 

<bean id="xxxConnectionFactoryImpl" class="com.ibm.mq.jms.MQQueueConnectionFactory">
      <property name="transportType" ref="transportTypeConst"/>
      <property name="queueManager" value="${xxx.queue.manager}"/>
      <property name="hostName" value="${xxx.queue.host}"/>
      <property name="port" value="${xxx.queue.port}"/>
      <property name="channel" value="${xxx.queue.channel}"/>
    </bean>
