Subject Re: Lost messages when streaming with Jetty
Date Tue, 14 Jun 2016 12:03:11 GMT
Hello,

I am not able to test this at the moment but what happens if you change the
first "from" to from("jetty:" + URI).log("${body} and ${headers}".to("")

In the case of the empty messages, does the log statement also show that
the body being empty?

You can also include debug level logs in your test to further break things
down to see if there is something obvious going on. To do that include the
variables:
private boolean debugBeforeMethodCalled:
private boolean debugAfterMethodCalled:

Include the methods:

@Override
protected void debugBefore(Exchange exchange,
org.apache.camel.Processor processor, ProcessorDefinition<?>
definition, String id, String label) {
  log.info("Before " + definition + " with body " + exchange.getIn().getBody());
  debugBeforeMethodCalled = true;
}

@Override
protected void debugAfter(Exchange exchange,
org.apache.camel.Processor processor, ProcessorDefinition<?>
definition, String id, String label, long timeTaken) {
  log.info("After " + definition + " with body " + exchange.getIn().getBody());
  debugAfterMethodCalled = true;
}



Best
Souciance
