This chapter is slightly different from others because almost all the other chapters were dealing with a particular way of binding services to ServiceMix. In this chapter we are going to address programming and/or deployment concerns which can be applied across any or all of the binding mechanisms covered in the other chapters.

Just as it is possible in normal programming such as web component development or server-side business component development, we can also attach various QOS features to the component deployment model in ServiceMix. The peculiar thing with these QOS features is that they are not hardwired through code along with the BCs or SEs, but applied over the components in a declarative manner. The advantage is that the characteristics of these QOS features can be easily changed by altering the particular configuration.

Let us now look into the selected QOS features and their support within ServiceMix.
