import java.math.BigDecimal;
public class BigDecimalDemo {

    public static BigDecimal sum(BigDecimal d,String s , BigDecimal b) {
        BigDecimal ans1 = (d.add(b));
        System.out.println("result inside BigDecimalDemo = "+ans1);
        return ans1;
    }
    to call it i use below approch but not able to call the java method :
int main(int argc, char* argv[])
{
    JNIEnv *env;
    string result_op = " " ;
    JavaVM * jvm;
    env = create_vm(&jvm);
    int i ;
    if (env == NULL)
        return 1;
    jclass clsH , ClsB =NULL;
    jmethodID midBigD  , midMain = NULL;
     ClsB = env->FindClass("java/math/BigDecimal"); // for bigdecimal object
     clsH = env->FindClass("com/fedex/test"); // for my class
     midMain  = env->GetMethodID(clsH, "sum", "(Ljava/math/BigDecimal;Ljava/lang/String;Ljava/math/BigDecimal)Ljava/math/BigDecimal");
     midBigD  = env->GetMethodID(ClsB, "<init>", "(D)V");
    jobject bd1 = env->NewObject(ClsB, midBigD, 12.1234);
    jobject bd2 = env->NewObject(ClsB, midBigD , 0.0500);
    jstring StringArg2 = env->NewStringUTF("STD");
    jobject result = env->CallObjectMethod(clsH, midMain,bd1,StringArg2,bd2 ); //Calling the  method.
     printf(" print the resultn ");
     //Release resources.
     int n = jvm->DestroyJavaVM();
}
