Subject Re: Proposal for a new camel-bean-validation component based on jsr 303
Date Sat, 20 Mar 2010 13:59:11 GMT
What would the difference be between just invoking a JSR-303 bean using
.to("bean:foo?method=validateMyFooPlease")

And just have a void method definition with the JSR-303 @ annotations?
I assume JSR-303 will throw some exception if the validation failed?

I recon I need to see a more concrete example to "get the picture" :)

But its a cool idea to leverage JSR-303 for validation.
We have a ticket in JIRA for some Predicate based validation as well.

So maybe JSR-303 can be wrapped with a Predicate so you can do CBR
routing and have valid -> foo and otherwise -> bar (invalid ones).
