Is it possible to propagate an exception to the parent route?
Hi there,
I'm wondering whether it is possible to propagate an exception to the parent route?
My configuration is the following:
<route id="parent">
<from uri="direct://parent"/>
<to uri="direct://child"/>
<onException>
<exception>org.test.MyException</exception>
<!-do something -->
</onException>
</route>
<route id="child">
<from uri=" direct://child"/>
<throwException ref="myException"/>
</route>
Is it possible to handle an exception thrown in the child route in the parent route?
Best Regards,
Sergey Zhemzhitsky

ok i did it this way:
Exception e = exchange.getProperty(Exchange.EXCEPTION_CAUGHT,
Exception.class);
i throught the exception is always set in the exchange, that is not correct.
you have access it through the properties

ok the real problem is that the exeption is gone when i want to wrap it,
is there an option to set the exception in the exchange in the doTry block
, or give it as an parameter to the processor ?

i´m trying that by wrapping an exception in a RuntimeCamelException and the
exception consumer is dewraping and throwing it again,
but at the producer i´m getting a nullpointer, so somewhere i´m loosing the
exception, cause i should get the runtimecamelException ...
any ideas ?
(thx, your answers already helped that much.. )
(Exception producer)
<from
uri="activemq:topic:services.global.xacml.authzRequests?transferException=true"
/>
<log message=" Xacml request consumed" />
<doTry>
<to uri="bean:pdp" />
<doCatch>
<exception>org.jboss.security.xacml.sunxacml.ParsingException
</exception>
<process ref="ExceptionWrapper"/>
</doCatch>
</doTry>
(Wrapper)
public void process(Exchange exchange) throws Exception {
Exception e = exchange.getException();
RuntimeCamelException wrapper = new RuntimeCamelException(e.getCause());
wrapper.setStackTrace(e.getStackTrace());
exchange.setException(wrapper);
}
(Exception consumer)
<from uri="direct:AuthzService" />
<to uri="bean:isAuthZBlocked?method=checkRequest" />
<doTry>
<to
uri="activemq:topic:services.global.xacml.authzRequests?transferException=true"
/>
<doCatch>
<exception>org.apache.camel.RuntimeCamelException</exception>
<process ref="ExceptionDeWrapper" />
</doCatch>
</doTry>
(DeWrapper)
public void process(Exchange exchange) throws Exception {
throw exchange.getException();
}

Hi,
If you use an ActiveMQ/JMS endpoint (http://camel.apache.org/jms.html)
with exchange of type InOut = request/reply, then the exception can be
transfered back if you set the property
transferException=true

Yes. In this case, you must disable the errorHandler in the second route.
Here is a camel example showing that in action
