Subject Re: ClassCastException in blueprint Route
Date Fri, 12 Jun 2015 04:32:17 GMT
John, 

Would you be able to post how the service is being declared along with the service properties
to ensure the correct service is being referenced in your consumer blueprint.

Thanks,
Andy

Hi,  

I have a service component, deployed as a separate bundle, that exports  
a package, com.example.services.configuration, and a service that  
implements a ConfigurationService interface in another package called  
LocalService:  

com.example.services.configruation.ConfigurationService  
com.example.services.configruation.local.LocalConfigurationService  

Another bundle imports the service using a filter (from the blueprint XML):  

<reference id="configurationService"  
interface="com.castlighthealth.services.configuration.ConfigurationService"  
filter="(realm=local)"/>  

and sets it as a property on a route bean. When I start this second  
bundle in ServiceMix I am getting a stacktrace [1] and just can't seem  
to figure out what I am doing wrong. Any guidance is very much appreciated.
