We don't have dedicated support for JBoss Fuse and unfortunately there is no intention to add one.
However, you may use the camel OpenTracing component and our OpenTracing integration. See some explanation on that on a related topic.
Alternatively, you may be able to add a custom interceptor, in which you can use our public API to create and manage (activate, close, end) transactions.
Once you have something that creates and activates transactions, all other supported technologies will just work as well (for example - JDBC or HTTP clients).
I hope this helps
