Hi,
I am using Camel 2.6.0 and have a very simple file based route from a single
input dir to a single output dir, with processors connected to both routes.
In my specific use case an exception raised in a processor is not
necessarily fatal and I do not want the stack trace information to get
logged.
The problem is even when I configure a global defaultErrorHandler and set
logStackTrace to false, when GenericFileOnCompletion catches an exception
from my processors, it uses its own internally configured
LoggingExceptionHandler as well and belches out an undesired stack trace.
Am I simply missing a configuration step here? How can I override
GenericFileOnCompletion's automatic use of LoggingExceptionHandler or
configure it to not emit stack traces? This seems like something really
simple that I must have overlooked, however I searched the docs and mailing
lists and haven't been able to find any more clues.
Below is my simple route which exhibits the behavior:
errorHandler(defaultErrorHandler().logStackTrace(false).logRetryStackTrace(false));
// set up a listener on the inbound file component
from("file://in").process(new Processor() {
public void process(Exchange e) throws Exception {
System.out.println("Received IN exchange: " + e.getIn());
}
}).to("file://out");
// set up a listener on the outbound file component
from("file://out").process(new Processor() {
public void process(Exchange e) throws Exception {
System.out.println("Received OUT exchange: " + e.getIn());
throw new Exception("Trouble!");
}
});
Here is the stacktrace generated:

attempt: 1 caught: java.lang.Exception: Trouble!
The last two log entries behave as expected based on
errorHandler(defaultErrorHandler().logStackTrace(false).logRetryStackTrace(false))
- what I would like is that the initial ERROR from GenericFileOnCompletion
behaves the same way as well. I know it seems like a pretty minor issue,
but it would be really great for my application to not have such a large log
file generated because of a unnecessary stack trace that gets generated
every time a retry of my file processor happens.
All that being said, this is my first time using Camel and I have to say it
is pretty awesome.
Thanks and best regards,
Mike
