Hi.
I must implement a native method that returns a Java string. So far so
good,
I can create the Java string from a const char * invoking
(*env)->NewStringUTF(env, const char *).
My problem is another. Sometimes, instead of a String, the method must
return
a null value. But, as the method is implemented natively, I donοΏ½t know
how to access the 'Java null' value/datatype/object/whatever.
I searched in jni.h for 'null' and found nothing, and the Java Tutorial
does not
mention this.
If someone knows how to return a 'Java null' from a Native JNI method,
please
let me know. Thanks in advance
Gabriel
