You need to use activemq instead of jms. And you should configure the activemq component to connect to the JMS broker you use.

Hi ,

Thanks a lot for that idea. PollingConsumer is working fine now and iam able to fetch the values back from queue. here is my exchange

printing exchange :::Exchange[JmsMessage: ActiveMQMessage {commandId = 5, responseRequired = true, messageId = ID:01HW195837-1465-1297675483829-0:38:1:1:1,

originalDestination = null, originalTransactionId = null, producerId = ID:01HW195837-1465-1297675483829-0:38:1:1, destination = queue://HTTPQueueNew,

how to post the value name=praga from this exchange back to the browser ?

I tried a sample

exchange.getOut().setBody("Book 123 is Camel in Action");

this is working fine. But it is hard coded value. How to send my value that was taken from queue back to the http browser?

Just grab whatever information you need from the Exchange that the PollingConsumer returns to you. And then store that information in the Exchange from the route.

If you use a Camel Processor then

public void process(Exchange exchange) throws Exception {
   ...
   Exchange jmsExchange = ... // polling consumer 
   ...
   // get stuff from jmsExchange and put in exchange
   String body = jmsExchange.getIn().getBody(String.class);
   String foo = jmsExchange.getIn().getHeader("foo", String.class);
   ..
   exchange.getOut().setBody("Hey this is from JMS " + body);
   exchange.getOut().setHeader("name", foo);

Hi,

I actually tried that but my body is printed null

camelContext.addComponent("activemq", activeMQComponent("tcp://localhost:61616"));

Endpoint endpoint = context.getEndpoint("activemq:queue:HTTPQueueNew");

PollingConsumer consumer = endpoint.createPollingConsumer();

Exchange exchange = consumer.receive();

System.out.println("printing exchange :::"+exchange);

String response = exchange.getIn().getBody(String.class);

System.out.println("response:::"+response);

but my response is null... I have printed my exchange in my previous post.

Hi,

When I tried using consumerTemplate.receiveBody iam getting null. Basically the body is null from queue. But if i see the exchange , the value is printed. Where could be the problem?

Hi,

Its working fine now. All i had to do is change my HTTP Request to string and then place it in queue.
