The String constructor(s) that take byte[] as parameter create a string by converting the bytes to characters based on an encoding. If you want a string that contains

9D 37 7B 10 CE 77 8C 49 38 B3 C7 E2 C6 3A 22 9A

You'll have to write a method that does that (as far as I know there isn't one in the java library). So basically:

public String toHexString(byte[] arr) {
    if (arr == null || arr.length == 0) {
        return "";
    }
    StringBuilder sb = new StringBuilder();
    sb.append(Integer.toHexString(arr[0] & 0xff));
    for (int i = 1; i < arr.length; i++) {
        sb.append(' ').append(Integer.toHexString(arr[i] & 0xff));
    }
    return sb.toString();
}
