Hi all, I am using a Topic to send and receive the message:
from("jms:topic:topic1").process(new Processor() { @Override public void process(Exchange exchange) throws Exception { System.out.println(exchange.getIn().getBody()); } }); The code to send the message: endPoint = getCamelContext().getEndpoint("jms:topic:topic1", JmsEndpoint.class); producer = getCamelContext().createProducerTemplate(); int i = 0; while(true){ Exchange exchange = endpoint.createExchange(); exchange.setPattern(ExchangePattern.InOnly); exchange .setBody(i++); m_producer.send(endPoint, exchange); Thread.sleep(1000); } I sent a message, wait for 1second, then send another with the content is i++. And the output I saw: 0 1 1 2 2 2 3 3 3 3 Why did I receive so many same messages? I expected the result must be: 0 1 2 3 Can someone help me on this?
