[resolved] How use cMessageRouter?

[Anonymous]

Hi,

I try to do a message router with talend ESB :

from("direct:start")
    .choice()
        .when(header("foo").startsWith("ba"))
            .log("je passe par le when")
            .to("direct:when")
        .otherwise()
            .log("je passe par le otherwise")
            .to("direct:other");

I could do it with a "javaDSL" but I'd like to use a "cMessageRouter".
How works the component cMessageRouter?
How generate a "when(Predicate)" and not a "when().language(…)"?

My environment :
[list=*]

Windows 7

Talend Open Studio version 5.6.0

Thanks,

Hi,

You could use cMessageRouter component but with simple language condition like this:
"${headers.foo} regex '^ba.*'"

Currently the Studio is not able to generate code to support

when(header("foo").startsWith("ba"))

but cMessageRoute + simple language would solve your use case above.
