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

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.
