Using properties file values with Camel Simple expression

I am trying to insert a value from a properties file into a simple expression
but it keeps throwing an exception

<route>
	<from uri="direct:signOut"/>
    	<transform>			
		<simple>${properties:my-host}</simple>
	</transform>
    	<to uri="nmr:HTTPService"/>
</route>

See exception below:

org.apache.camel.RuntimeCamelException:
org.apache.camel.FailedToCreateRouteException: Failed to create route
route56 at: >>> Transform[simple{${properties:my-host}}] <<< in route:
Route[[From[direct://signOut]] -> [Transform[simple{%3CAK_BS... because of

I went through the doc on http://camel.apache.org/simple.html and I saw
this:

properties:locations:key 	 String 	 Camel 2.3: Lookup a property with the
given key. The locations option is optional. See more at Using
PropertyPlaceholder. 

I wonder what the proble is.

regards.
