My ActiveMQ client is setting few custom header while posting message to ActiveMQ Queue, as shown below
MessageProducer producer = session.createProducer(destination);
TextMessage message = session.createTextMessage("<Message>Test</Message>");
message.setStringProperty("ID", "XYZ");
message.setStringProperty("CODE", "COUNTRY_CODE");
producer.send(message);
In WSO2 ESB sequence, I am trying to retrieve "ID" and "CODE" as
<property xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" name="ID" expression="get-property('axis2', 'ID')" scope="default" type="STRING"/>
<property xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" name="CODE" expression="get-property('axis2', 'CODE')" scope="default" type="STRING"/>
But this is returning null, I even tried to set the scope as transport. Please advise.
You have to use the following expression because the custom jms headers are stored in the transport layer.
<property name="CREATE_PROXY - Config Params"
expression="get-property('transport','TRANSPORT_ID')"/>

I am trying to connect to RabbitMQ queues present in the server using apache-camel configuration.
It works fine when I create the queues with durable field false and auto-delete field true. But doesn't work when either of them is otherwise.
applicationContext.xml file looks like this -
<bean id="customConnectionFactory" class="com.rabbitmq.client.ConnectionFactory">
<property name="host" value="localhost" />
<property name="port" value="5672" />
<property name="username" value="guest" />
<property name="password" value="guest" />
<property name="virtualHost" value="Test" />
</bean>
<bean id="testBean" class="test.TestBean" />
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from
uri="rabbitmq://localhost:5672/ex1?connectionFactory=#customConnectionFactory&queue=Q1&autoDelete=true&durable=true" />
<to uri="bean:testBean?method=hello" /> <!-- This method consumes and prints the message -->
</route>
</camelContext>
Here I need to specify the properties autoDelete and durable for the queue Q1 not the exchange ex1. (I have already specified for the exchange in the URI)
As the error is -
Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'auto_delete' for queue 'Q1' in vhost 'Test': received 'true' but current is 'false', class-id=50, method-id=10)
Here reply-code=406 indicates that the parameters of queues/exchanges are not matching with the actual configuration. Its because of the queues properties here.
As I don't have the access to the remote queues, I cannot change the properties of queues. (Example I stated here is localhost)
Note: I have a requirement of doing this using spring beans only.
I am using a property "INC" to store a incoming message(which is showing properly in logs) and doing mapping properly by payload mediator.
The modified structure that I am getting by payload is as below.(which is getting properly mapped)
Later, I am using callout mediator as below to get response from this endpoint.
using LogText to see the response.
Then adding filter as below:
<property name="INC" expression="get-property('IntRequest')" scope="default" type="STRING"/>
<property name="LogText" value="call response" scope="default" type="STRING"/>
<filter xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:platformFaults="urn:faults_2015_1.platform.webservices.com" source="//platformFaults:code/text()" regex="WS_CONCUR_SESSION_DISALLWD">
<then>
<log level="full" separator=",*Fault in Call***">
<property name="REQUEST" expression="get-property('INC')" scope="default" type="STRING" />
</log>
</then>
<else/>
</filter>
But, here I am not getting value of REQUEST.. it is showing the value of "call response"..
How will I get the value of REQUEST properly??
Try to use the enrich mediator to store the request message body
<enrich>
<source clone="true" type="body"/>
<target property="Request_Message" type="property"/>
</enrich>
then call the property
<log>
<property expression="get-property('Request_Message')" name="REQUEST"/>
</log>
where did you define "IntRequest" property in your sequence? I couldn't find it in your configuration. If you change the log level to custom it would be more clear to see the value of request in the system log
I want to implement a solution in Spring-JMS with activeMQ where I want to create a durable subscription to a topic. The purpose is that if a subscriber closes the subscription for a while and once again recreates the durablesubscription with same client id and subscription name, the subscriber should receive all the messages which were delivered during the time subscription was closed.
I want to implement the following logic mentioned in the ORACLE URL for durable subscriptions: https://docs.oracle.com/cd/E19798-01/821-1841/bncgd/index.html
But I am unable to perform this using spring-jms. As per the URL I need to get messageConsumer instance and call close() on that method to stop receiving message temporarily from the topic. But I am not sure how to get it.
Following is my configuration. Kindly let me know how to modify the configuration to perform this.

why not calling DefaultMessageListenerContainer.stop(); to stop the container and consumers ?
you can inject jmsContainer to another bean and close it when you want and call start() later.
all messages sent to the broker when your durable consumer is offline will be stored until it reconnect.
to make subscription durables you need to add this to jmsContainer bean
<property name="subscriptionDurable" value="true" />
<property name="cacheLevel" value="1" />
you can add a subscriptionName or the class name of the specified message listener will be used.
You can add a clientID to the connectionFactory
<property name="clientID" value="${jms.clientId}" />
or use
<bean class="org.springframework.jms.connection.SingleConnectionFactory"
id="singleConnectionFactory">
<constructor-arg
ref="connectionFactory" />
<property name="reconnectOnException" value="true" />
<property name="clientId" value="${jms.clientId}" />
</bean>
and update jmsContainer
<bean id="jmsContainer"
class="org.springframework.jms.listener.DefaultMessageListenerContainer"
p:durableSubscriptionName="gxaa-durable1" p:clientId="gxaa-client1">
<property name="connectionFactory" ref="singleConnectionFactory" />
<property name="destination" ref="adiTopic" />
<property name="messageListener" ref="adiListener" />
<property name="subscriptionDurable" value="true" />
<property name="cacheLevel" value="1" />
</bean>
UPDATE :
if your adiListener implements org.springframework.jms.listener.SessionAwareMessageListener it have to define method onMessage(M message, Session session) and when you have the session you can call javax.jms.Session.unsubscribe(String subscriptionName)
subscriptionName is defined above and can be injected to this bean or the class name of the specified message listener can be used.
I'm new to RabbitMQ and Spring Integration.
I have a use case to consume JSON message from a channel, convert it to an object. One of the field that I need to set in the object is the message Id(delivery.getEnvelope().getDeliveryTag()) of the message that we receive from rabbitMQ which we need for ack handling after all the business logic.
How to do it using spring integration?
Here is my xml configuration.
<bean id="devRabbitmqConnectionFactory" class="com.rabbitmq.client.ConnectionFactory">
<property name="brokerURL" value="#{props[rabbitmq_inputjms_url]}" />
<property name="redeliveryPolicy" ref="redeliveryPolicy" />

<property name="cacheProducers" value="false" />
</bean>
<int-jms:channel id="devJMSChannel" acknowledge="transacted"

<int:transformer id="devObjectTransformer" input-channel="devJMSChannel" ref="devService" method="readEventFromRabbitMQ"
output-channel="devPacketChannel">
<int:poller fixed-rate="10" task-executor="devObjectTransformerExecutor" />
</int:transformer>
The transformer method "readEventFromRabbitMQ" gets the message String from msg.getPayload() converts it into object and sends it to the output channel. But not sure how to get the message Id in the transformer class. Can somebody help me with this?
public List<DevEventRecord> readEventFromRabbitMQ(Message<EventsDetail> msg){
DevEventRecord[] eventRecords=null;
EventsDetail expEvent = null;
long receivedTime =System.currentTimeMillis();
int packetId = -1;
try{
monitorBean.incrementDeviceExceptionPacketCount();
expEvent = msg.getPayload();
LogUtil.debug("readExceptionEvent :: consumed JMS Q "+expEvent);
eventRecords = dispatchPacket(expEvent);
}
catch(ProcessingException pe){
notifyAck(expEvent.getUniqueId(),,,,);
}
catch(Exception ex){
notifyAck(expEvent.getUniqueId(),,,,);
LogUtil.error("Exception occured while reading object in readEvent , "+ex.toString());
}
return getEventRecordList(eventRecords);
}
The deliveryTag is presented as message header after an <int-amqp:inbound-channel-adapter> under the key AmqpHeaders.DELIVERY_TAG.
I don't understand why you mix AMQP and JMS, but anyway those channel implementations don't populate headers from received message. It is out of their responcibity.
Please, use <int-amqp:inbound-channel-adapter> and here is a sample how to ack message manually using deliveryTag header.
We have been testing the message processors and queues on wso2 esb. We have been using the sampling processor quite successfully to just log data to a DB. This POX end to end. The sampling processor correctly dequeues a message and sends it to the endpoint. The endpoint is defined as POX and non-chunked, and all this works well.
We decided to try the store and forward processor as we wanted to test out the guaranteed delivery mechanism. So we created a new processor and defined it as store and forward. In the main sequence that stores the message, we added the target.endpoint property before storing the message. The property was set to the same endpoint that was being used in the sampling scenario.
However - what have found is that in this mode, the message transformation does not happen correctly. The content type is set to text/html and the output is chunked. This causes our service to return a 415 error.
We have tried adding messageType, contentType etc to multiple place, to the axis http sender transport, etc, but it seems to make no difference at all.
Any guidance on this would be appreciated
Define the following property in the sequence before sending to the endpoint
<property name="DISABLE_CHUNKING" value="true" scope="axis2"/>
The JS code below simply inserts the messageID into the return payload to the caller. Using this with a sampling processor and sequence that simply sends to the same endpoint works fine.
