Question

I have a simple Camel application that is tracing to a JMS endpoint. I am currently experiencing an issue where it appears that the received JMS message is not being acknowledged (It is reading from a queue without any messages being put on it and the current queue depth is not reducing).

Any idea on what may be causing this issue?

Tracing Route

    from("jms.tracer")
        .id("openlink-input-trace")
        .process(new Processor()
        {
            @Override
            public void process(Exchange exchange) throws Exception 
            {
                System.out.println("test");
            }
        });

Spring JMS Config

<bean id="tracerQueueConnFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiTemplate" ref="jndiTemplate" />
    <property name="jndiName" value="${jms.openlink-tracer-queue-qcf.jndiname}" />
</bean>

<bean id="proxyTracerQueueConnFactory" class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
    <property name="targetConnectionFactory" ref="tracerQueueConnFactory" />
    <property name="username" value="${jms.openlink-tracer-queue-qcf.username}" />
    <property name="password" value="${jms.openlink-tracer-queue-qcf.password}" />
</bean>

<bean id="jmsTrace" class="org.apache.camel.component.jms.JmsComponent">
    <property name="connectionFactory" ref="proxyTracerQueueConnFactory" />
    <property name="destinationResolver" ref="jndiResolver" />
</bean>

Spring Endpoint Config

    <endpoint id="jms.tracer"
              uri="jmsTrace:queue:${jms.openlink-tracer-queue.jndiname}" />

EDIT:

This is using TibcoEMS as the broker.

All I can see in the logs is the following:

Answer 1

I knew I was doing something stupid!

I took a closer look at the trace messages and realized that tracing was enabled on my context causing my tracer route to be traced and thus a nice little infinite loop.
