I would like to revisit this issue and find a way to read routing configuration from a data base for each message that comes in.
The servicemix xml file would still be used to define the available components but a routing (sequence of components to traverse) would be loaded by a BC each time a message comes in. The idea was that such a routing configuration would be attached to the in message in a first BC. Is there any existing component that can serves this purpose, that is to read a (custom) routing configuration form the in message directly and forward to correct service after each step?

All your routing needs can be fullfilled by the EIP component, using the ContentBasedRouter and Pipeline (i guess you are using an InOnly MEP). The HTTP will send an InOnly exchange to a Pipeline. The Pipeline will send an InOut exchange to a first ContentBasedRouter. The ContentBasedRouter will route the exchange to the needed XSLT stylesheet and send back the answer to the Pipeline. The Pipeline will forward the transformed exchange to a second ContentBasedRouter which will route it to the final destination (HTTP, SMTP ...) If the XSLT should be associated with the final destination, you can use a single ContentBasedRouter and put the several Pipelines between it and the final destination, each Pipeline invoking an XSLT component. Not sure if I'm very clear, and mail is not a very good way to express schema :( In short, use EIP and one XSLT per endpoint.
