Java wrapped around C++ 1

[mgallot]

An application we are considering for purchase is written in C++, but comes with an EJB interface. Do you think that Java developers would be limited because of the underlying code? The Java programmers want to have the open architecture, full J2EE functions available to them. Short of testing the actual API, do you see any glaring problems?

While it is possible to interface C/C++ programs with Java, Unless there are no other viable solutions, I would advise against it, because if something goes wrong, it makes debugging a nightmare.

I'd tend to be wary about performance as well. There's a non-trivial overhead for every JNI call, which may tend to make operations that are normally very cheap significantly more expensive.
