Re: onException is ignored
I just saw the org.slf4j.helpers.MarkerIgnoringBase is use to write the warning
and error message. I guess it may relate to your log configuration.

Re: onException is ignored
So when using onException it's really important not to use a component that
is already partaking in the transaction being rolled back? I get that now,
but it's not immediately obvious.
Does this explain why the log()ged message, Account Not Found. Message
discarded. does not appear in the console though?

Re: onException is ignored
Hi
No the onException should be triggered even for TX.
You may try to configure onException after errorHandler.

Re: onException is ignored
Since you use transactions then sending a message to a JMS queue is
also rolled back, and hence the onException appears to not send the
message to the account not found queue. But its because the tx is
rolled back.
You can define a 2nd jms component, eg using a different name than
jms, that does not become part of the same tx, and use that in the
onException.

Re: onException() silently ignored if after transacted()
Hi
Yeah we will in the future break up the DSL to have a route setup part
and then the regular part for the route flow.
The former should setup onException, transaction, onCompletion,
interceptors and what not, eg cross function stuff.
And the latter is for the route.
The problem is that its currently in the same level. However we didnt
want to do that just out of the blue as it will cause people having to
rearrange the existing routes.

Here is me with more questions/bug report.
I've noticed that Camel can be very sensitive on order operators are
invoked in route builder.
For example, transacted() has to be after onException(). Otherwise,
onException() is completely ignored and message will just pass through
error handling code like it's the part of regular route. See example:
// Fails
from(direct:fails)
.transacted()
.onException(Exception.class)
.handled(true)
.useOriginalBody()
.redeliveryDelay(10)
.maximumRedeliveries(2)
.retryAttemptedLogLevel(LoggingLevel.WARN)
.retriesExhaustedLogLevel(LoggingLevel.ERROR)
.to(mock:error)
.end()
.to(mock:end);
// Ok
from(direct:ok)
.onException(Exception.class)
.handled(true)
.useOriginalBody()
.redeliveryDelay(10)
.maximumRedeliveries(2)
.retryAttemptedLogLevel(LoggingLevel.WARN)
.retriesExhaustedLogLevel(LoggingLevel.ERROR)
.to(mock:error)
.end()
.transacted()
.to(mock:end);
// Test fails
�...@test
�...@dirtiescontext
public void testTransactionOnException() throws InterruptedException {
errorMock.expectedMessageCount(0);
endpoint.expectedMessageCount(1);
fails.sendBody(Hello World);
errorMock.assertIsSatisfied();
endpoint.assertIsSatisfied();
}
Ideally, Camel should either allow onException() after transacted() or
throw an error if trying to set onException() after transacted(). To
silently ignore onException() seems to be most undesirable.
