You need to put your variables into fields outside of the methods, then set them inside the methods only stating the variable, and not the type.

Thank you micecd.

No problem, would you mind clicking the thanks button under my username? ^^

And did you get your project working?

It is working. I didn't get it going though. I'm working with someone whose trade is programming. So he fixed it. Doesn't help me much in terms of learning. I need to spend more time on JAVA.

I use code to trade forex, been working in MQL, but the broker I've been using is closing its retail devision. So now I have to make a move and the best alternative option is using Oanda's REST API, with JAVA. Just takes so damn long to make anything work in JAVA, just don't have the experience to hunt down problems in a hurry.

--- Update ---

In fact, maybe you can tell me why this isn't working, it's either a malformed link problem or I'm sending the header wrong:

            HttpResponse resp = httpClient.execute(httpGet);
            HttpEntity entity = resp.getEntity();
 
            if (resp.getStatusLine().getStatusCode() == 200 && entity != null) {
                InputStream stream = entity.getContent();

                    JSONObject tick = (JSONObject) obj;
 
                    // unwrap if necessary
                    if (tick.containsKey("tick")) {
                        tick = (JSONObject) tick.get("tick");
                    }
 
                    // ignore heartbeats
                    if (tick.containsKey("instrument")) {
                        System.out.println("-------");
 
                        String instrument = tick.get("instrument").toString();
                        String time = tick.get("time").toString();
                        double bid = Double.parseDouble(tick.get("bid").toString());
                        double ask = Double.parseDouble(tick.get("ask").toString());
 
                        System.out.println(instrument);
                        System.out.println(time);
                        System.out.println(bid);
                        System.out.println(ask);
                    }
                }
            } else {
                // print error message
                String responseString = EntityUtils.toString(entity, "UTF-8");
                System.out.println(responseString);
            }
 
        } finally {
        	httpClient.close();
        }
    }
}

The error message is:

{
"code" : 4,
"message" : "The access token provided does not allow this request to be made",
"moreInfo" : "http:\/\/developer.oanda.com\/docs\/v1\/auth\/#overview"
}

And I'm very sure I am sending the right token. So it must be the header delivering it wrong.

The problem is in the code. I had someone else check out my token and it works. I suspect I am sending the header wrong or the token wouldn't have been rejected, sometimes I get a different error message as if the token is going through, but the link is malformed, so my JAVA question is, is there a problem with these lines, one of them appears not to be working properly:

HttpUriRequest httpGet = new HttpGet(domain + "/v1/prices?accountId=" + account_id + "&instruments=" + instruments);
httpGet.setHeader(new BasicHeader("Authorization: ", "Bearer " + access_token));

They've updated their code. There were deprecated classes in their old example, that I changed in my example. Probably used the wrong class.

https://github.com/oanda/java-api-st...Streaming.java

So I've been running, but they still have a deprecated class in their example. Not sure why they updated half the blood thing. Now this line doesn't work...

} finally {
// httpClient.getConnectionManager().shutdown();
}

Thanks for the attempts to help...
