array of strings in JNI

I know this is a JAVA thing but Im having issues with the C portion of the code. I know there isnt a jStringarray type of or anything but I was trying to get an array of strings to pass into the C code for a simple example does anyone have any ideas

Code:

#include <jni.h>
#include <stdio.h>
#include "HelloWorld.h"

JNIEXPORT void JNICALL
Java_HelloWorld_print
(JNIEnv *env, jobject obj, jstring javaString, jcharArray arr)
{
	jchar* buf;
	jint i =0;

	const char *nativeString = (*env)->GetStringUTFChars(env, javaString, 0);
	printf("%s\n", nativeString);

	buf = (*env)->GetCharArrayElements(env, arr, NULL);
	if (buf == NULL) {
		return 0; /* exception occurred */
	}
	for(i =0; i < 5; i++){
		printf("%s\n",buf[i]);
	}	


	printf("Hello World!\n");
	(*env)->ReleaseStringUTFChars(env, javaString, nativeString);
	(*env)->ReleaseCharArrayElements(env, arr, buf, 0);
	return;
}

No clue about Java (so I could be totally wrong), but this line looks suspicious

Code:

buf = (*env)->GetCharArrayElements(env, arr, NULL);

Shouldn't it be

Code:

buf = (*env).GetCharArrayElements(env, arr, NULL);

No that part is fine because the env is a struct i think in jni.h and most of the examples using env function calls use the ->. The code i posted is C i already i java code that should be right but My c code isnt work
