PUT request using OAuth (java) fails to authenticate

[GoogleCodeExporter]

1. perform PUT request using OAuth (java) using following code

import net.oauth.OAuth;
import net.oauth.OAuthAccessor;
import net.oauth.OAuthConsumer;
import net.oauth.OAuthMessage;
import net.oauth.ParameterStyle;
import net.oauth.client.OAuthClient;
import net.oauth.client.httpclient3.HttpClient3;
import net.oauth.signature.RSA_SHA1;

public class XeroTest
{

  public static void main(String[] args)
  {
    String apiURL="https://api.xero.com/api.xro/2.0/";

    String consumer_privateRSAKey="-----BEGIN RSA PRIVATE KEY-----\n"
        + "MIICXAIBAAKBgQDbpie9UmO0nRLMTIf3tNzqf1ARnNeFQHvaV6XHeNY9kfUvnHv8\n"

        + "BsUN0XGNJ4SxChvc5rLvpTHpjTZYgZohJhuaI6WNFzg=\n"
        + "-----END RSA PRIVATE KEY-----";

    String consumerKey="MZFHMTC3NWFLZTCXNGE4YTG3NGVJMJ";
    String consumerSecret="OQDTQCDEXS21UURUVTSURLE9ARQ7UP";

    OAuthConsumer consumer = new OAuthConsumer(null,consumerKey, null, null);
    consumer.setProperty(RSA_SHA1.PRIVATE_KEY, consumer_privateRSAKey);
    consumer.setProperty(OAuth.OAUTH_SIGNATURE_METHOD, OAuth.RSA_SHA1);
    consumer.setProperty(OAuthClient.PARAMETER_STYLE, ParameterStyle.AUTHORIZATION_HEADER);

    OAuthAccessor myAccessor = new OAuthAccessor(consumer);
    myAccessor.accessToken = consumerKey;
    myAccessor.tokenSecret = consumerSecret;

    try {
      // PUT Contacts example
      String postXML="<Contact>" +
            "<Name>Contact Name</Name>" +
            "<ContactNumber>002</ContactNumber>" +
            "</Contact>";
      OAuthClient client = new OAuthClient(new HttpClient3());
      OAuthMessage m = client.invoke(myAccessor, OAuthMessage.PUT, apiURL+"Contacts", OAuth.newList("xml",postXML));
      System.out.println(OAuthMessage.readAll(m.getBodyAsStream(), "UTF-8"));
    }
    catch ( Exception e ) {
      System.out.println(e.toString());
    }

  }
}

I expect to see a response from Xero with the newly created contact (like if I 
were to use POST method); instead the following is printed
11/08/2010 3:41:16 PM org.apache.commons.httpclient.HttpMethodDirector
