Dear all, I have written the following section of code after following this tutorial:
https://netbeans.org/kb/docs/websvc/twitter-swing.html
// more code above
private static final String OAUTH_BASE_URL = “http://twitter.com/oauth”;
/**
* Please, specify the consumer_key string obtained from service API pages
/
private static final String CONSUMER_KEY = “zE7iBvNSdLeHa032aMZqtA”;
/*
* Please, specify the consumer_secret string obtained from service API pages
*/
private static final String CONSUMER_SECRET = “my secret key here”;
private OAuthParameters oauth_params;
private OAuthSecrets oauth_secrets;
private OAuthClientFilter oauth_filter;
private String oauth_access_token;
private String oauth_access_token_secret;
public void setResourcePath(String format) {
String resourcePath = java.text.MessageFormat.format("statuses/user_timeline.{0}", new Object[]{format});
webResource = client.resource(BASE_URI).path(resourcePath);
}
/**
* @param responseType Class representing the response
* @param since query parameter
* @param since_id query parameter
* @param page query parameter
* @param count query parameter
* @return response object (instance of responseType class)
*/
public <T> T getUserTimeline(Class<T> responseType, String since, String since_id, String page, String count) throws UniformInterfaceException {
String[] queryParamNames = new String[]{"since", "since_id", "page", "count"};
String[] queryParamValues = new String[]{since, since_id, page, count};
return webResource.queryParams(getQueryOrFormParams(queryParamNames, queryParamValues)).accept(javax.ws.rs.core.MediaType.TEXT_XML).get(responseType);
}
private MultivaluedMap getQueryOrFormParams(String[] paramNames, String[] paramValues) {
MultivaluedMap<String, String> qParams = new com.sun.jersey.api.representation.Form();
for (int i = 0; i < paramNames.length; i++) {
if (paramValues[i] != null) {
qParams.add(paramNames[i], paramValues[i]);
}
}
return qParams;
}
public void close() {
client.destroy();
}
/**
* You need to call this method at the beginning to authorize the application to work with user data.
* The method obtains the OAuth access token string, that is appended to each API request later.
*/
public void login() throws IOException, UniformInterfaceException {
Form requestTokenResponse = getOAuthRequestToken();
String oauth_verifier = authorizeConsumer(requestTokenResponse);
Form accessTokenResponse = getOAuthAccessToken(requestTokenResponse, oauth_verifier);
oauth_access_token_secret = accessTokenResponse.getFirst("my secret token here");
oauth_access_token = accessTokenResponse.getFirst("561089922-KrK6UmFMxQkv1QgCiYrWSVgITCFdZi03XXX2K1Of");
}
private Form getOAuthRequestToken() throws UniformInterfaceException {
WebResource resource = client.resource(OAUTH_BASE_URL).path("/request_token");
oauth_params = new OAuthParameters().consumerKey(CONSUMER_KEY).signatureMethod(com.sun.jersey.oauth.signature.HMAC_SHA1.NAME).version("1.0").nonce().timestamp();
oauth_secrets = new OAuthSecrets().consumerSecret(CONSUMER_SECRET);
oauth_filter = new OAuthClientFilter(client.getProviders(), oauth_params, oauth_secrets);
resource.addFilter(oauth_filter);
return resource.get(Form.class);
}
I am relatively new to Java, and am getting this stacktrace when I try and run the program:
Exception in thread "AWT-EventQueue-0" com.sun.jersey.api.client.UniformInterfaceException: GET http://twitter.com/oauth/request_token returned a response status of 301 Moved Permanently

I would be grateful if someone could explain to me how to solve this.
Many thanks,
