I don't think so, as the container (or the ecxhange factory) has no way to know which jbi exchange is currently handled by the component. And you can not use a thread local, has the component may delegate the exhcange processing to another thread. That's the reason why it has been implemented in servicemix-common. Do you see something else ?

A question again. If I have a lw component which opens a new message exchange the correlation id has to be propageted in the component itself. Would it be better or is it possible to do this automaticaly in the exchange factory?
