从Qt C ++调用Java函数

Question

Is it possible to call java function from Qt Application and if so, how? Do I need to update java source for such task? I have Qt Desktop Opensource edition.

Answer 1

First of all think twice before calling java from C/C++. For Android it allow you call some API function of OS, but you pay with perfomance and some hard catching errors.

Qt designed pretty easy way for calling Java: package - androidextra But if you need call it on desktop there is a way to avoid it: JNI(as Nejat says).

Here is simple example of using it: http://www.codeproject.com/Articles/22881/How-to-Call-Java-Functions-from-C-Using-JNI
