> Hi,
> In documentation link http://camel.apache.org/simple.html following is written
> Camel 2.11: To refer to a type or field by its FQN name. To refer to a field
> you can append .FIELD_NAME. For example you can refer to the constant field
> from Exchange as: org.apache.camel.Exchange.FILE_NAME
> When I tried it it works.
> But for example I have class Constants which contain inner class
> InnerConstants which have a field. I cannot access it from following way.
> ${type:Constants.InnerConstants.fieldName}.
> Exception Found: Cannot find class Constants.InnerConstants.fieldName
> Following is the structure of my Constant class
> class Constants {
> public static String test ="Test1234";
> public static class InnerConstants {
> public static String fieldName = "fieldName"
> }
> }
> My route was:
> <route>
> <camel:from uri="stream:in" />
>
> <camel:setBody><simple>${type:Constants.InnerConstants.fieldName}</simple></camel:setBody>
> <log loggingLevel="INFO" message="${body}" />
> </route>
> Let me know if you need any other clarification.
