Hi. I can't make authenticat with OAuth on Java2ME. Error report is "Failed to validate oAuth signature and token".

MIDletOAuthDialogWrapper page = new MIDletOAuthDialogWrapper(this);
page.setConsumerKey(CONSUMER_KEY);
page.setConsumerSecret(CONSUMER_SECRET);
page.setCallbackUrl("http://chirica.do.am/");
page.setOAuthListener(new OAuthDialogListener() {...});
page.login();

CONSUMER_KEY and CONSUMER_SECRET a take from my apps page on twitter.
Device Nokia 3110c.
What is the reason of the problem and how can I fix it?

	First off, please make sure your device's date, time and timezone are correct.

	Ok! This help me. But to fix this bug I set not my timezone. I think about this and will write my dessision.

	It is not a bug. OAuth algoritm requires the correct date/time to work properly.

	Next step. I have PIN and I want to auth user. But when I invoke MIDletOAuthDialogWrapper.login(PIN) I have exception: "Invalid state: call login() method first". But, when I call MIDletOAuthDialogWrapper.login(), by app is closing and browser opens, so any steps in my App after it can not be made. 1. login(); <app closed> 2. login(PIN) <exception> How can I fix it?

	Unfortunately, if your app is closed, you cannot authenticate, since we need the instace of MIDletOAuthDialogWrapper alive. It keeps some internal state required to complete the process.

	May be Token data it can be stored in midlets RecordStore ?

	It is not only one token we are talking about.

	If the user exits the application, whether or not he will be authorized again the next time? What data should be stored to make authorization automatically next time?

	Once you are authenticated and you have your access token, it is your app's responsability to store it and further usage.

	Hi, You are forgetting to mark Twitter API ME lib in Project -> Properties ->Build Path -> Order & Export. If you do not do that, the lib wont be packaged along with your source code. Regards,
