Subject RE: ActiveMQ custom plugin
Date Fri, 02 Feb 2018 08:23:14 GMT
Yes I am using 5.x currently.
Using Apache Camel I am routing messages from ActiveMQ to IBM MQ.

	<!-- Configure IBM WebSphere MQ connection factory -->
	<bean id="websphereConnectionFactory" class="com.ibm.mq.jms.MQConnectionFactory">
		<property name="transportType" value="1" />
		<property name="hostName" value="SC1234MC.sss.se.scania.com" />
		<property name="port" value="1414" />
		<property name="queueManager" value="SC1234MC" />
	</bean>

	<bean id="websphereConfig" class="org.apache.camel.component.jms.JmsConfiguration">
		<property name="connectionFactory" ref="websphereConnectionFactory" />
		<property name="concurrentConsumers" value="1" />
	</bean>

	<bean id="websphere" class="org.apache.camel.component.jms.JmsComponent">
		<property name="configuration" ref="websphereConfig" />
	</bean>

	<camelContext trace="false" id="wmqToAmqContext"
		xmlns="http://camel.apache.org/schema/blueprint">
		<route id="wmqToAmqBridge">
			<from uri="activemq:topic:demo" />
			<log message="The message contains ${body}" />
			<to uri="websphere:queue:LQ.SCCO3879.ST5" />
		</route>
	</camelContext>

Let's go back to basics.

Are you using 5.x or Artemis?

You say you're routing messages from ActiveMQ to IBM MQ. How is that being
done?

I don't wish to add headers in the message I pasted. This message I am
getting from user and it is content. Even the tag header is part of
content. But when I route the message from Active MQ to IBM MQ certain
attributes like destination topic name and message id need to be added.

Also I am using MQTT client to publish a message on ActiveMQ specifying the
topic name and message. I need to add that topic name as destination and
also want to remove JWTtoken from message.

Publication:

I need *Demo* to be added in headers and remove jwtToken from message. I
removed it. But what method I can use in ActiveMQ to publish it on Topic
Demo instead of message with jwtToken value.

I Hope I am able to explain you better :)

Bharat Gupta

Oh, and I missed your second question. I would expect that you could add
headers similar to how the code you posted removed some. Does your question
mean that you tried that and it didn't work? If so, how did it fail?
