Having Issues with the E*Trade OAuth API (Java)

Question

I'm trying to code a program that will trade stocks in a sandbox environment with the E*Trade API. I am using their sample code as a guideline and currently am getting an issue with the .getAuthorizeURL() method. It says that it is undefined for type String however, after decompiling the OAuth jar I am stuck in a rut about how to solve this issue.

import com.etrade.etws.account.Account;
import com.etrade.etws.account.AccountListResponse;
import com.etrade.etws.oauth.sdk.client.IOAuthClient;
import com.etrade.etws.oauth.sdk.client.OAuthClientImpl;
import com.etrade.etws.oauth.sdk.common.Token;
import com.etrade.etws.sdk.client.ClientRequest;
import com.etrade.etws.sdk.client.Environment;
import com.etrade.etws.sdk.common.ETWSException;
import com.etrade.*;

import java.awt.Desktop;
import java.net.URI;
import java.*;
import java.io.IOException;

public class OAuth
{
    public static void main(String[] args) throws IOException, ETWSException
    {
        //Variables
        IOAuthClient client = null;
        ClientRequest request = null;
        Token token = null;
        String oauth_consumer_key = null; // Your consumer key
        String oauth_consumer_secret = null; // Your consumer secret
        String oauth_request_token = null; // Request token 
        String oauth_request_token_secret = null; // Request token secret

        client = OAuthClientImpl.getInstance(); // Instantiate IOAUthClient
        request = new ClientRequest(); // Instantiate ClientRequest
        request.setEnv(Environment.SANDBOX); // Use sandbox environment
        request.setConsumerKey(oauth_consumer_key); //Set consumer key
        request.setConsumerSecret(oauth_consumer_secret);
        token = client.getRequestToken(request); // Get request-token object

        oauth_request_token  = token.getToken(); // Get token string
        oauth_request_token_secret = token.getSecret(); // Get token secret
    }

    public String Verification(String client, ClientRequest request)
    { 
         String authorizeURL = null;
         authorizeURL = client.getAuthorizeUrl(request); // E*TRADE authorization URL
         URI uri = new java.net.URI(authorizeURL);
         Desktop desktop = Desktop.getDesktop();
         desktop.browse(uri);

         return authorizeURL;
    }
}

Show us the exact error message that you are getting, and the line of code that you're getting it on. — Robert Harvey, Jul 22 '14 at 17:08
Oh, sorry, the exact error message is "The method getAuthorizeUrl(ClientRequest) is undefined for the type String" on line 43. It is in the Verification method. — Frodgers, Jul 22 '14 at 17:14
Yes, the method from the OAuth jar when i decompiled it is "public abstract String getAuthorizeUrl(ClientRequest paramClientRequest) throws ETWSException;" I can edit that into my post if that would make it easier to read. — Frodgers, Jul 22 '14 at 17:18
That looks like a different error than the one you originally reported. — Robert Harvey, Jul 22 '14 at 17:24
Oh, okay, I'm still fairly new to Java and coding in general, how would you recommend I go about investigating these errors to fix them? Thank you for your help, by the way. — Frodgers, Jul 22 '14 at 17:27

You need to configure your build path to include the Apache log4j logger (org/apache/log4j/Logger) in your external JARs. It's use is buried down in the ETRADE code.

What are you editing your code in? It should be easy to find instructions for your development environment. APACHE is free and you can download the JAR here: http://logging.apache.org/log4j/2.x/

Note the requirement from ETRADE (https://us.etrade.com/ctnt/dev-portal/getContent?contentUri=V0_Code-Tutorialhttps://us.etrade.com/ctnt/dev-portal/getContent?contentUri=V0_Code-Tutorial): Java SDK To proceed with this tutorial, you must first have completed the installation of the E*TRADE Java SDK, including:

•Java 1.6 or later installed

•3rd-party jars installed

•E*TRADE Java SDK libraries in your CLASSPATH

You can get instructions for all of the jars here https://us.etrade.com/ctnt/dev-portal/getContent?contentUri=V0_Code-SDKGuides-Java

If you were using Eclipse IDE, for example, you can follow these instructions How to import a jar in Eclipse

I'm currently using eclipse. Thank you for your help and the download link. Edit: Thanks, you answered my question. I have all of the other 3rd party jars installed along with the E*Trade SDK. Must have just been careless and didn't install this one. — Frodgers, Jul 22 '14 at 17:52
