Subject RE: Camel onException for different HTTP error codes
Date Mon, 04 May 2015 12:11:27 GMT
Trying out "when" now. We can check with statusCode:500 etc in simple then. 
Thanks for your response.

Thanks and Regards,

You can use onWhen to an exception as the predicate to trigger or not.
Then you can use some java code as the predicate to check for those http headers and figure
out what to do.

There is also a retryWhile you can use etc.

Camel in Action book chapter 5, in the end of this chapter documents this. And you can find
some bits on the Camel web site too.
