camel - exception handling

Hi
Am trying to catch an exception and based on that continue the flow. Using
below code. But on xml validation I get following

'camel:continued'. One of

Re: camel - exception handling

Posted by yogu13 <yo...@gmail.com>.

Hello Jack,

if handled is set to "false" then the exception is not handled, so it will
be stored as an exception on the exchange and break out from the route.

Continued should be available for use, Not sure why isnt it working in your
case.. can you upgrade to latest and check if you still get the issue?


Regards,
-Yogesh

Nothing seems to jump out.

Would you be able to share you entire camel context?

Thanks

Hi Andrew,  

I'm also hitting the same exception. If <continued> is available to use, why  
is not working? This is what I have and Camel doesn't seem to be happy with  
it. I want to log the error and move on with the route rather than stopping  
the flow. If I set Handled = false, wouldn't it break the flow?  

<onException>  
<exception>java.lang.Exception</exception>  
<continued><constant>true</constant></continued>  
<log message="*** Message: ${exception.message} ***" />  
<log message="${exception.stacktrace}" />  
</onException>  

How do I make the continued to work fine? I'm using Came 2.9.2.  

Thanks.

Re: camel - exception handling

Continued is not a valid option in the catch block. By default the route will continue since it is the assumption that the catch logic will handle any any failures and continue. You can set the <camel:handled>false</camel:handled> if you want to propagate the exception.
