Do you mind stating which documentation you have read, that talks about a quick fix example?
There is some details about QuickFix in the Fuse Mediation Router (Camel) documentation
and i've also read the link you shared, both links mention the following in the "EXAMPLE" section:
"The source code contains an example called RequestReplyExample that demonstrates the InOut exchanges for a consumer and producer. "
since it says that the source code contains said example, i was trying to install it to try it and to see if i could do some load testing with said example, but i'm unable to find it.
That example is part of unit testing the camel-quickfix component. The source is here
There is possible some more examples as well
