Hi, I am trying to develope a wrapper for a "c API". There are using Char * as a OUT parameter,in the sense it's initialized in the c function. I am tried with jstring..But that value is not reflecting in Java program... JNIEXPORT jint JNICALL Java_Wrapper_GetVersion(JNIEnv *env,jobject obj, jstring jversion) { unsigned long unStatusCode = 0; unsigned char *uszVersion=NULL; unsigned long unVersionLen = 0; unStatusCode = GetVersion(uszVersion,&unVersionLen); jversion=env->NewStringUTF((const char*)uszVersion); return (jint)1; } jversion value is not reflecting in Java program.. And one more thing can u tell how to impl   More>>
