>             Project: Camel
>          Issue Type: Bug
>          Components: camel-core
>    Affects Versions: 2.11.0
>            Reporter: Claus Ibsen
>            Assignee: Claus Ibsen
>            Priority: Minor
>             Fix For: 2.12.0

> Calling a bean from a route like
> {code}
>                 from("direct:start")
>                     .to("bean:myBean?method=doSomething()")
>                     .to("mock:result");
> {code}
> Notice the method has () as parameters. Which would refer to a method with no-args. 
> But if the method has 1 arg like
> {code}
>         public static void doSomething(Exchange exchange) {
>             exchange.getIn().setHeader("foo", "bar");
>         }
> {code}
> We get this error about some type converter probem
> {code}
> Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: java.lang.String to the required type: org.apache.camel.Exchange with value 
> {code}
> We should have a better error message.
> If removing () then Camel can call the method as it can do parameter matching.
