I need to port a C library to Java so it can run on the Blackberry platform (mobile, native application). The options I am considering are:
- bytecode conversion (cibyl, etc)
- Complete port
- Wrap C code around Java using JNA (would this even work for Blackberry?)
Please let me know which option is best. thanks
Aha. Some quick googling says "No, JNI does not work for blackberry" source:

So you're stuck with bytecode conversion and complete port. Since I have no idea what bytecode conversion is, I'd go with a complete port, so long as you are familiar with both languages. If you can define bytecode conversion for me, I might be able to give you a better answer.
We also have an in-house developed C library for core functionality of our iOS and Android apps.
I asked about using cibyl to run this on BlackBerry in the form of a .jar and the good news is that it's possible: https://twitter.com/#!/simonkagstrom/status/114581622833152000 [backup of the tweet: "Sure, that's how #waze on the blackberry works."]
You can also try MoSync: http://twitter.com/#!/MoSync/status/115088826430533632 [backup of this one: "Yup, you can use MoSync for BB. There's "experimental" Blackberry support in MoSync 2.6, already used in live apps!"]
And David A Roberts, developer of LLJVM sent me this: "I'm not familiar with BlackBerry development, but I see no obvious reason why LLJVM wouldn't work, so long as the library doesn't rely too much on things like the C POSIX library (e.g. dirent.h, etc) - I never got around to implementing this fully. Otherwise LLJVM would need to be updated suitably..."
Side note: BlackBerry's new Tablet OS and planned BBX phones actually have a native SDK but this QNX based stuff is quite unpopular. We just need to wait if BBX is going to become a success since Java based solutions are just too much risks.
