re-writing old fetch request to work with 0.8 version

I found this embedded kafka example online (
https://gist.github.com/mardambey/2650743) which I am re-writing to work
with 0.8

Can someone help me re-write this portion:

val cons = new SimpleConsumer("localhost", 9090, 100, 1024)
var offset = 0L

var i = 0

while (true) {
val fetchRequest = new FetchRequest("TEST", 0, offset, 1024)

for (msg <- cons.fetch(fetchRequest)) {
i = i + 1
println("consumed [ " + i + "]: offset = " + msg.offset + ",
payload = " + Utils.toString(msg.message.payload, "UTF-8"))
offset = msg.offset

I have this so far:

val partition = 0
var offset = 0L

var i = 0
while (true) {
//val fetchRequest = new FetchRequest("TEST", 0, offset, 1024)
val fetchRequest = new FetchRequestBuilder().addFetch(topic,
partition, offset, 1024).build()

val fetchResponse: FetchResponse = consumer1.fetch(fetchRequest)

val messageSet = fetchResponse.messageSet(topic, 0).iterator.toBuffer
println("consumed Message " + messageSet(0).message)

This currently loops forever b/c it isn't incrementing the offset or anything.
I'm confused b/c I believe there is no more offset as things are more
user friendly with an incrmeenting counter.

Any help would be appreciated.
