Re: Camel, JBI + JMS priority

Fri, 12 Sep 2008 04:06:34 -0700

I just committed a test [1], which shows the same basic user story as your example ( I take out the JBI part of HTTP BC). 
It works with the latest Camel code,  please check it out.

Hi

Can you try the below code which just set the out message's body ?

class EndProcessor implements Processor {

    public void process(Exchange exchange) {
        System.out.println("======= > " +
exchange.getIn().getBody(String.class));
        exchange.getOut().setBody("<message>out</message>");
    }
}

When I added processor at the end of the flow I've got
NullPointerException.
Used processor:
class EndProcessor implements Processor {

    public void process(Exchange exchange) {
        System.out.println("======= > " +
exchange.getIn().getBody(String.class));
        Message copy = exchange.getIn().copy();
        copy.setBody("<message>out</message>");
        exchange.setOut(copy);
    }
}

It looks like the jms producer can't get out message before Future timed out. 
 From your route code, you did not set the out message back.

// endpoint only for testing
        from("jbi:service:http://stock/destination";)
            .to("file:log");
// Please using the process to set the out message

Hello,
I tired to create priority queue with Camel inside Service Mix, but
after
two days I stucked.

General idea is:
1) one cxf endpoint on Service Mix have priority 0
2) second cxf endpoint on Service Mix have priority 9
3) destination service can process only one message at time

I want configure only CXF and Camel endpoints, without jms queue.

My routes:
package pl.bpsa.smx3.services.router;

import javax.xml.transform.dom.DOMSource;

import org.apache.camel.builder.RouteBuilder;

public class RoutesProvider extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("jbi:service:http://stock/high";) // important messages
            .to("jms:queue:foo?priority=9");
        from("jbi:service:http://stock/low";)
            .to("jms:queue:foo?priority=0");

        from("jms:queue:foo")
            .to("jbi:service:http://stock/destination";);

        // endpoint only for testing
        from("jbi:service:http://stock/destination";)
            .to("file:log");
    }

}

All process are stoped when camel try put message to queue. How to fix
this
issue?
