Reference :http://dev.twitter.com/pages/auth

I have get signature_base_string,signature_key,oauth_signature and all other parameters that are the same with twitter tutorial.

  1. signature_base_string POST&https%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest_token&oauth_callback%3Dhttp%253A%252F%252Flocalhost%253A3005%252Fthe_dance%252Fprocess_callback%253Fservice_provider_id%253D11%26oauth_consumer_key%3DGDdmIQH6jhtmLUypg82g%26oauth_nonce%3DQP70eNmVz8jvdPevU3oJD2AfF7R7odC2XJcn4XlZJqk%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1272323042%26oauth_version%3D1.0

  2. signature_key oauth_consumer_secret="MCD8BKwGdgPHvAuvgvz4EQpqDAtx89grbuNMRd7Eh98&"

  3. oauth_signature 8wUi7m5HFQy76nowoCThusfgB+Q=

Now I request http://api.twitter.com/oauth/request_token use "POST" method and get response code 411. I use a servlet doGet() when I request it from my Firefox. What do I miss in the code or any mistake? Who can help me?

What is the purpose of this exercise, if I may ask? - Buhake Sindi
Check your oauth_callback, its value seems already be encoded. Try oauth_callback=http://... instead - longbkit
Never, Never, and Never display your consumer secret on any post. - Buhake Sindi
If you cut-pasted OAuth examples from Twitter, it won't help as the oauth_timestamp is extremely old and will never validate. - Buhake Sindi

Before I can help you, what your InputStream from your HTTP Error 411 state?

Add the following code.

InputStream is = null;
if (httpURLCon.getResponseCode() != 200) {
    is = httpURLCon.getErrorStream();
} else {
    is = httpURLCon.getInputStream();
}

Update: Your Authorization header value must never contain a space. The value must be OAuth<space><comma-delimited-value-without-space>.
