Is it possible to call java method from C code with SWIG generated JNI?

Question

I am trying to use SWIG to generate my JNI. I already have JNI code that is working, but it is hand written and it is getting more and more complicated and difficult to maintain.

Some of my functions in C are called from Java, and then they call some methods in Java (probably it is not a good idea, but it is working for now)...

I am wondering if it is possible for SWIG to generate that kind of JNI code?

Answer 1

Yes it should be possible.

The following languages are also supported in swig-1.3.6 onwards: Java JDK 1.1 and newer.

Quoted from http://www.swig.org/compat.html

Answer 2

我知道的这种类型的JNI唯一包装器是Jace和JunC ++ ion ，它们都是基于C ++的，因此不符合您的需求。
