I have been looking at these for days and still haven't have mush success.
I have install and run activeMQ on a server. Created a queue called "testUpdate". I also have another queue on another server, let call this "forward" and this is on the IBM MQ (WMQ).
So we have testUpdate on ActiveMQ and forward on WMQ. I want the message on forward queue to be placed into testUpdate queue. Trying to use Camel for this process.
So the setup in ActiveMQ has an XML(activemq.xml) that I can place spring beans and configure to do the routing. In this xml, I added http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd to the xmlns and then added
import resource="camel.xml"
In this new xml, I have the following:
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<description>Example Camel Route</description>
<from uri="mqseries:forward"/>
<to uri="activemq:testUpdate"/>
</route>
</camelContext>
<bean id="mqseries" class="com.ibm.mq.jms.MQQueueConnectionFactory">
<property name="transportType" value="1"/>
<property name="hostName" value="172.00.12.21/>
<property name="port" value="xyza"/>
<property name="queueManager" value="manager"/>
<property name="channel" value="srvcChannel"/>
</bean>
<!--
Lets configure some Camel endpoints
http://camel.apache.org/components.html
-->
<!-- configure the camel activemq component to use the current broker -->
<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent" >
<property name="connectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="vm://amq-broker?create=false"/>
<property name="userName" value="${activemq.username}"/>
<property name="password" value="${activemq.password}"/>
</bean>
</property>
</bean>
</beans>
I added the jar file com.ibm.mq.allclient.jar into the lib folder of ActiveMQ. When running the program, I am getting this exception: java.lang.ClassNotFoundException: javax.jms.JMSRuntimeException
It sounds like I am missing the websphere jar file? Is this correct?

You can use users camel extra component https://github.com/camel-extra/camel-extra/blob/master/components/camel-wmq/README.md to get messages from wmq without using the JMS wrapping and then send messages to ActiveMQ with custom camel component https://camel.apache.org/components/latest/activemq-component.html. See also a similar topic Apache Camel with IBM MQ.

I use both IBM MQ and ActiveMQ on a regular basis. This example below will show you some sample configuration options. Please make sure you configure these to your own use cases.
//ActiveMQ connection factory
<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent" destroy-method="doStop">
<property name="configuration">
<bean class="org.apache.camel.component.jms.JmsConfiguration">
<property name="concurrentConsumers" value="1" />
<property name="maxConcurrentConsumers" value="1" />
<property name="acceptMessagesWhileStopping" value="true" />
<property name="acknowledgementModeName" value="CLIENT_ACKNOWLEDGE" />
<property name="cacheLevelName" value="CACHE_CONSUMER" />
<property name="connectionFactory">
<bean class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop">
<property name="maxConnections" value="1" />
<property name="MaximumActiveSessionPerConnection" value="500" />
<property name="connectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="${activemq1.brokerUrl}" />
<property name="userName" value="${activemq1.username}" />
<property name="password" value="${activemq1.password}" />
<property name="redeliveryPolicy">
<bean class="org.apache.activemq.RedeliveryPolicy">
<property name="maximumRedeliveries" value="-1" />
</bean>
</property>
</bean>
</property>
</bean>
</property>
</bean>
</property>
</bean>
//IBM MQ connection factory
<bean id="ibmmq" class="org.apache.camel.component.jms.JmsComponent" destroy-method="doStop">
<property name="concurrentConsumers" value="1" />
<property name="maxConcurrentConsumers" value="1" />
<property name="connectionFactory">
<bean class="org.springframework.jms.connection.SingleConnectionFactory" destroy-method="destroy">
<constructor-arg>
<bean class="com.ibm.mq.jms.MQQueueConnectionFactory">
<property name="transportType" value="1" />
<property name="channel" value="${channel}" />
<property name="hostName" value="${hostname}" />
<property name="port" value="${port}" />
<property name="queueManager" value="${queueManager}" />
</bean>
</constructor-arg>
</bean>
</property>
</bean>

You can use jms component to consume the message from IBM MQ and use activemq component to post it to ActiveMQ
have a look at the following links
http://camel.apache.org/jms.html http://camel.apache.org/activemq.html
Thanks, Gibu
