Help in JAVA and JNI and C language

Dears ,

I have a small task , I have c code that define JNI . the java will call the header

the c code is :

JNIEXPORT jstring JNICALL

JNICALL Java_project_projectNative_getdata

(JNIEnv *env, jobject, jstring password)

{

// example format , unsigned char pin[] = {0x31, 0x31, 0x31, 0x31};

....

...

..

}

what I want is just a code that receive the jstring Password and assign the value of it to unsigned char pin[] as hex

the input of password is String and it will be like this "1,1,1,1"

it should be converted to unsigned char : {0x31, 0x31, 0x31, 0x31}

Thanks
