You can replace it, but not append to it.

Thanks to Igor for the original post.

It can’t be realized without custom processors because although several expression languages can retrieve the exception message, neither the XQuery or XSLT components work with fault messages.

The Retrieving schema at <Schema Location> message shouldn’t be displayed.

Fixed in 4.2.

errorHandler(deadLetterChannel().maximumRedeliveries(); // default is 5

http://camel.apache.org/dead-letter-channel.html

http://enterpriseintegrationpatterns.com/DeadLetterChannel.html

The default error handler is DeadLetterChannel, but you may want to change it to LoggingErrorHandler, at least:

errorHandler(loggingErrorHandler(SampleRouteBuilder.class.getName()));

The next major version is most certainly going to use the DefaultErrorHandler in Apache Camel 2.0-M2.

http://camel.apache.org/dead-letter-channel.html

http://camel.apache.org/defaulterrorhandler.html

You might also use exception clauses.

If you get a java.lang.NoClassDefFoundError for org.apache.camel.processor.aggregate.AggregationStrategy or other Apache Camel classes when deploying servicemix-camel components, you will need to migrate to OSGi components.
