These documents are worth a browse...

in particular this describes how we invoke a bean inside a route

you can either use it inside a route...

from("jms:someQueue").bean(MyBean.class, "myMethodName");

or using the @Consume annotation

You can omit "myMethod" and Camel will probably do the right thing but
it doesn't do any harm to be totally explicit.
