Exception

getService

protected Object getService(ServiceConfiguration serviceConfiguration)

getTopicService

protected Object getTopicService(ServiceConfiguration serviceConfiguration)

Get the service as a topic. This means we want to contact every service that is a part of this topic. We've grabbed all the services that are a part of this topic and we want to make sure that we get everyone of them = that is we want to circumvent loadbalancing and therefore not ask for the service by it's name but the url to get the exact service we want.

getQueueService

protected Object getQueueService(ServiceConfiguration serviceConfiguration)

Because this is a queue we just need to grab one.

getMessage

public PersistedMessageBO getMessage()
