Re: Propogate CXF Exception to Camel

Fri, 02 Mar 2012 14:23:46 -0800 

Hi Willem,
I upgraded to Camel 2.8.4 and CXF 2.4.6 and I still see this behavior.  Here
is my route.  It basically reads from a folder and calls a web service:

                <endpoint id="foobarWebserviceEndpoint"
                
uri="cxf:bean:foobarRelocationService?dataFormat=PAYLOAD&amp;loggingFeatureEnabled=true"
/>

                
                <camel:route id="foobarRelocationHandlerConnector"
errorHandlerRef="foobarRelocationDeadLetterErrorHandler">
                        <camel:from uri="foobarRelocationInputDir" />
                        <camel:log message="Received file for foobar 
Relocations: ${file:name}"
/>
                        <camel:setHeader headerName="operationName">
                                <constant>opName</constant>
                        </camel:setHeader>
                        <camel:setHeader headerName="operationNamespace">
                                <constant>http://www.namespace.com/</constant>
                        </camel:setHeader>
                        <camel:to uri="foobarWebserviceEndpoint" />
                        <camel:log message="Called foobar intermediary" />
                </camel:route>

        </camel:camelContext>

        
        <bean id="foobarRelocationDeadLetterErrorHandler"
class="org.apache.camel.builder.DeadLetterChannelBuilder">
                
                <property name="deadLetterUri" 
value="foobarRelocationDeadLetterDir" />
                
                <property name="redeliveryPolicy"
ref="foobarRelocationRedeliveryPolicyConfig" />
        </bean>

        
        <bean id="foobarRelocationRedeliveryPolicyConfig"
class="org.apache.camel.processor.RedeliveryPolicy">
                
                <property name="maximumRedeliveries" value="3" />
                
                <property name="redeliveryDelay" value="5000" />
        </bean>

I get a connection refused error when I shut down the server:

After this the route continues rather than trying redelivery.  If I throw an
exception processor in there:

        <camel:to uri="bean:throwit"/>

        <bean id="throwit" class="org.search.processor.Process"/>

Then I see the redelivery attempts happen.  This does not happen with the
web service 'connection refused' though...

Any ideas?

Thanks,
Yogesh
