camel bean processor question

[sriramch <sr...@consortemedia.com>]

I am trying to route to a bean instance by specifying a method-name using
Camel 1.6. This specific route is defined as below:

<camel:bean ref="myBean" method="myMethod"/>

The method myMethod is overloaded

public void myMethod(){
}

public void myMethod(Date date){
}

Depending on how I order my methods in the class, either of these seem to be
getting picked up by the BeanProcessor. Is there any way I can force it to
use the method without any arguments? If this is not possible, what is a
good way to always pass null as the date parameter to the myMethod
invocation? Any pointers would be very helpful.

Thanks
Sriram

Hi

As there are 2 methods with the same name, you need to help Camel pick the
one.
You can add the @Body annotation to the one you want to invoke and Camel
will prefer this one.

But that would require you to define at least 1 parameter for the method.
public void myMethod(@Body Object body)

Otherwise you can always add a little delegate method that has a unique
name.


In Camel 2.0 we have added a @Handler annotation to the method itself as a
kind of "use this method please".
