Dear Quinn, I found the following Stackoverflow post asking the same as me: https://stackoverflow.com/questions/34617646/return-back-from-current-route-in-apache-camel-and-continue-routing
First I did this:
<camel:onException>
<camel:exception>/SomeException/</camel:exception>
<camel:handled><camel:constant>true</camel:constant></camel:handled>
<camel:log loggingLevel="WARN" message="ERROR en la
ruta cfdi33Validation ${body.class} ${exception}" />
<camel:setHeader headerName="fatal">
<camel:constant>true</camel:constant>
</camel:setHeader>
<camel:to
uri="log:cfdi33Validation?level=DEBUG&showCaughtException=true&showStackTrace=true&showHeaders=true"/>
</camel:onException>
and
<camel:onException>
<camel:exception>/SomeException/</camel:exception>
<camel:handled><camel:constant>true</camel:constant></camel:handled>
<camel:log loggingLevel="WARN" message="ERROR en la
ruta cfdi33Validation ${body.class} ${exception}" />
<camel:setHeader headerName="fatal">
<camel:constant>true</camel:constant>
</camel:setHeader>
<camel:to
uri="log:cfdi33Validation?level=DEBUG&showCaughtException=true&showStackTrace=true&showHeaders=true"/>
<camel:stop/>
</camel:onException>
The handled=true made the route finish, but did not return to the caller
route, it tried directly to return a response to JMS (and failed because
of missing processing).
Based on the post answer, and my own failures, I modified the route definition to look like this:
<camel:route id="cfdi33Validation">
<camel:from uri="direct:Validation"/>
<camel:from uri="vm:Validation"/>
<camel:onException>
<camel:exception>/SomeException/</camel:exception>
<camel:continued><camel:constant>true</camel:constant></camel:continued>
<camel:log loggingLevel="WARN" message="ERROR en la
ruta cfdi33Validation ${body.class} ${exception}" />
<camel:setHeader headerName="fatal">
<camel:constant>true</camel:constant>
</camel:setHeader>
<camel:to
uri="log:cfdi33Validation?level=DEBUG&showCaughtException=true&showStackTrace=true&showHeaders=true"/>
</camel:onException>
<camel:process ref="testCfdi33Processor"/>
<camel:process ref="cfdi33XSDValidatorProcessor" id="XSD
CFDI33"/>
<camel:process ref="cfdi33SchematronValidatorProcessor"
id="SCH CFDI33"/>
<camel:process ref="cfdi33extractCfdi33Fields"
id="extractFields"/>
<camel:process ref="descontarPlanRecepcionProcessor"
id="descontarPlan CFDI 3.3"/>
...
</camel:route>
After an exception is raised, OnException sets fatal and the following
the processors return immediately if the see the /fatal/ header.
public class ExtractCFDI33FieldsProcessor implements Processor, InitializingBean {
@Override
public void process(Exchange ex) throws Exception {
if(ex.getIn().getHeader("fatal", false, Boolean.class)==true)
return;
...
This a [very] ugly workarround, but barely works. I think would be
better to cut the route processing short (like a return in the middle of
a function).

I don’t see an <onException …> element in the route - are you handling the exception?

Sometimes a processor in the middle encounters an error (and throws an exception). At this point the validation has to stop, not executing the remainder of the route AND returning to the caller to manage the exception. The pattern is a request-reply. The route has the following structure: <camel:route id="cfdi33Validation"> <camel:from uri="direct:cfdi33Validation"/> <camel:from uri="vm:cfdi33Validation"/> <camel:process ref="testCfdi33Processor"/> <camel:process ref="cfdi33XSDValidatorProcessor" id="XSD CFDI33"/> <camel:process ref="cfdi33extractCfdi33Fields" id="extractFields"/> <camel:process ref="descontarPlanRecepcionProcessor" id="descontarPlan CFDI 3.3"/> <camel:process ref="cfdi33ValidarTfdCertificado"/> ... <camel:process ref="cfdi33SelloTfdValidator"/> </camel:route> Sometimes the descontarPlanRecepcionProcessor encounters an error (and throws an exception) . The route must return the error to it's caller route. The exception must be propagated to the caller route. Currently the exception is logged and discarded, but the original caller timeout because it expects an answer that never arrives. I have read the docs, but cannot figure how to do the above. Can anyone have any idea? Regards, -- Miguel Ruiz Velasco Sobrino FCM Computacion Mexicana SAPI de CV http://fcm.com.mx (55)5682-0041
