ReportIncident tutorial - Logging Issue..
Using version 2.14.0 - First time i've used Camel, so excuse if this is obvious - but I'm having some difficulties getting the first step of the ReportIncident tutorial working. Seems there have been some recent changes to the LogEndpoint (see CAMEL-7599) - might have affected this example :-
http://camel.apache.org/tutorial-example-reportincident-part2.html
I had to modify sendToCamelLog as per below to get it working - call endpoint.setProvidedLogger(..) as well as endpoint.start() ..
Does this point to a bug or does the example require updating ?
Thx Jon
================
private void sendToCamelLog(String name) {
try {
// get the log component
Component component = camel.getComponent("log");
// create an endpoint and configure it.
// Notice the URI parameters this is a common pratice in Camel to configure
// endpoints based on URI.
// com.mycompany.part2 = the log category used. Will log at INFO level as default
LogEndpoint endpoint = (LogEndpoint) component.createEndpoint("log:org.apache.camel.example?level=DEBUG");
// endpoint.setCamelContext(camel);
endpoint.setProvidedLogger(LoggerFactory.getLogger(ReportIncidentEndpointImpl.class));
endpoint.start();
// create an Exchange that we want to send to the endpoint
Exchange exchange = endpoint.createExchange();
// set the in message payload (=body) with the name parameter
exchange.getIn().setBody(name);
// now we want to send the exchange to this endpoint and we then need a producer
// for this, so we create and start the producer.
Producer producer = endpoint.createProducer();
producer.start();
// process the exchange will send the exchange to the log component, that will process
// the exchange and yes log the payload
producer.process(exchange);
// Exception was being generated during processing, but not thrown.
Exception exc = exchange.getException();
if (exc != null) throw exc;
// stop the producer, we want to be nice and cleanup
producer.stop();
} catch (Exception e) {
// we ignore any exceptions and just rethrow as runtime
throw new RuntimeException(e);
}
}

Hi
That tutorial is very old, though you have discovered a little bug. So
feel free to log a JIRA ticket
http://camel.apache.org/support
If you want to get started with Camel then I recommend reading this
article also - it has a great little example to go along with the
article

Sure - in fact, the message payload was not being logged at all.
Added code to check the exception after producer.process(..) - there was a
NPE generated during processing, as the logger had not been initialised -
see below for stacktrace.

Hi Jon,
Could you describe what was your original issue? Stacktrace will be useful :) .
Cheers.
