QuickFIX or QuickFIX/J?

I can develop with either C or Java. What implementation is most stable开发者_开发问答 for production use? What implementation is most actively developed?

If you are a C developer, use the C++ library(Quickfix). Both libraries are not that difficult to grasp. I have used both of them and am currently using QuickfixJ. Give priority to that library, which uses the language you are most comfortable in. Have a go through the examples to make it easier to understand. Java examples have a default config file, but you would need to write you own config file for the C++ examples.
