I know that there is not a C/C++ API for SwiftMQ. But, there is also not a clear definition of the SMPQ protocol so that I could get some engineers at my company to write one (or contract out).

From the SwiftMQ perspective, would it be better for us to write a Swiftlet to act as the C/C++ API bridge (much like the current JMS Swiftlet), or adapt to the SMPQ protocol?

Here is another one, Jace, which provides a nice C++ lib on top of JNI. Looks very promising:

The SMQP protocol isn't open. It's complicated as well and we need the freedom to change it anytime. I would recommend to use the Java Invocation API. This API is part of JNI but isn't very well known. However, it's very powerful because you spawn a JVM from your native code and can then instantiate any class and call any method including JMS/JNDI which keeps you vendor independent. So all what you need is to spawn the JVM and instantiate JNDI/JMS classes and call the resp. methods.

Look here:

And here for the basic JNI functions you can use:
