Generate hmacSha1 signature in node.js same as java?

That is how i am generating hmacsha1 signature in java

private static byte[] hmac_sha1(String crypto, byte[] keyBytes, byte[] text) {
Mac hmac = null;

    try {
        hmac = Mac.getInstance(crypto);
        SecretKeySpec macKey =
            new SecretKeySpec(keyBytes, "RAW");
        hmac.init(macKey);
        System.out.println("hmac: "+Arrays.toString(keyBytes));
        return hmac.doFinal(text);
} catch (Exception e) {
    // NOTE. Deviation from reference code.
    // Reference code prints a stack trace here, which is not what we
    // want in a production environment, so instead we rethrow.
    throw new UndeclaredThrowableException(e);
    }

}

I need help to generate same in node.js. Can someone please help me on this? As people mentioned that I need to show what I have tried here is the code that I have written in node.js to create a same functionality

Ocra.hmacSha1 = function(crypto, keyBytes, text) {
    var digest, hmac;
    hmac = nodeCrypto.createHmac(crypto, new Buffer(keyBytes, 'utf8'));
    console.log(this.bin2String(keyBytes));
    digest = hmac.update(new Buffer(text, 'utf8')).digest('hex');        
    return this.hexStr2Bytes(digest);    // here i am converting string into bytes array    
};

The above code is not producing the desired results. If I pass these parameters to java code crypto: sha1 keyBytes: [ 49, 50, 51, 52, 53, 54, 55, 56, 57, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 48 ] text:79678265454958727984804583726549455458817848560000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

they produce different result and in node.js it produces different results.

Note: In java crypto is HmacSHA1 and text is in form of array not string as you can see in code as well.
