Re: DeadLetterChannel Configuration Camel 1.4

Thu, 24 Jul 2008 05:05:03 -0700

The bug that I found just related to the RouterBuilder not the Spring configuration part. After adding spring test[1] and went though the code revision, I found James already fixed the Spring part of configuration in CAMEL-662[2]. Please make sure you are using the official Apache Camel 1.4.0 release.

Hi  Marc
FYI  I just did a quick fix for your issue.
Please check out the latest camel snapshot for verification.

Cheers,

Hi ,
I just dug the code, you can't set the errorHandler from CamelContext in Camel1.4.0, I just fill a JIRA[1] for this issue. 
You can walk around it by using the DSL.

Hi,
I am attempting to upgrade from Camel 1.3 to Camel 1.4 so we can use its 
exception handling features and configuration.  I have been trying to
configure the DeadLetterChannel all day via errorHandlerRef attribute on the Camel Context and on the route element within the Camel context to no avail. 

My setup is as follows:
-Defined Spring configuration file that defines my Camel CXF endpoints and Camel Context with its routes. -Run the application through the Maven Jetty Plugin. -Make a web service request via SOAPUI to the create method on the Archetype Web Service with an error in XML payload of the request. This error in the payload causes the JAXB unmarshall to pass null to the archetypeBSO bean 
defined in Camel route.
-The DAO within the BSO throws an exception when it attempts to save a null object. -The stacktrace shows that the Camel Route is being followed but the DeadLetterChannel configuration is not. Any suggestions? What am I doing wrong? Any help will be greatly 
appreciated.

Regards,
Marc

Here is my configuration.
