How can I handle exception message?
Hi,
I want to do some special thing according to Exception Type. But there are a
lot of route and when an exeption occured I send the message to deadletter
queue.
errorHandler(
deadLetterChannel("jms:queue:deadletterqueue")
);
I wrote a class for deadletterchannel processor.
@Component("ProcessorForSendingEmail")
public class ProcessorForSendingEmail implements Processor {
@Override
public void process(Exchange exchange) {
System.out.println("HATAAAAAAAAAA :"+exchange.getOut().isFault());
System.out.println("YYYYYYYYYYYYY
:"+exchange.getOut().getHeader(Exchange.EXCEPTION_CAUGHT));
System.out.println("FFFFFFFFFFFFF :"+exchange.getException());
System.out.println("HATAAAAAAAAAA :"+exchange.getIn().isFault());
System.out.println("YYYYYYYYYYYYY
:"+exchange.getIn().getHeader(Exchange.EXCEPTION_CAUGHT));
}
}
But all of them is null... I need to write Exception Message... How can I
reach exception message in Dead Queue. Thanks...

your help Willem and Claus...

You are using the jms endpoint to receive the message, you need to
enable the transferExchange option and make sure your exceptions are
serializable.

If you use a JMS destination as dead letter channel, then it only
stores the message. Not the stacktrace.
If you want to include the stacktrace, you will have to put that into
the message as a header yourself, and ensure the value of the header
is valid according to the JMS spec, such as a java.lang.String type.
See the JMS wiki page for details about mapping to/from JMS.

Thanks my friends, but it didnt work :(
In my main classs :
...
camelContext.setHandleFault(true);
...
My Dead Letter Queue URL :
jms:queue:deadletterqueue
Dead Letter Queueu Processor :
from("jms:queue:deadletterqueue").process(new ProcessorForSendingEmail ());
Processor class for deadletterqueue :
@Component("ProcessorForSendingEmail")
public class ProcessorForSendingEmail implements Processor {
@Override
public void process(Exchange exchange) {
Throwable exception =
exchange.getProperty(Exchange.EXCEPTION_CAUGHT,Throwable.class);
System.out.println("HATAAAAAAAAAA :"+exception);
}
}
For test I throw an exception from a proccessor :
@Component("Test3")
public class Test3 implements Processor {
@Override
public void process(Exchange exchange) throws Exception {
if (1==1) throw new Exception("BENDEEEEEEEEEE");
exchange.getIn().setHeader("IB.messageName", "rmsPlstAssign");
}
}
Result : HATAAAAAAAAAA :null
I NEED EXCEPTION MESSAGE... Please help me :(

Hi,
The exception is stored in the properties of exchange.
You can get it by using below code
Throwable exception = exchange.getProperty(Exchange.EXCEPTION_CAUGHT,
Throwable.class);

Use exchange.getIn() to access the message.
