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).
