    Default Integrate Java and C

    Hi,
    Is it possible to call a C function from Java. I need to develop Java interface which calls C functions in a daemon. The problem is that the Java and C are in different daemons. Is there a way to combine the two languages?

    Regards
    Peter

    Default Re: Integrate Java and C

    There are 2 main ways to call external functions from Java: The Java Native Interface (JNI), or Java Native Access (JNA). Personally I've never worked with JNA before, but I have worked with JNI before.

    For a quick starter tutorial on JNI, see An Introduction to the Java Native Interface.

    Thank you for the answer! One thing I don't understand - is it doing to work if the Java code and the C code are in two different Linux daemons? Or thy must be in one folder compiled together?
