Help with SIM using Java

blnigro1 — Tue, 04 Dec 2012 20:46:24 GMT

Hello All,

I would like to start by saying that I am new to these forums and I apologize ahead of time if what I am asking isn't that difficult to do or along those lines (aka newbish).

First off I am currently in charge of creating a connection from our SharePoint portal (Forms) to Authorize.Net for our payment option. So what I figured would be best would attempt to get something working in a test enviorment . I chose Java as the lanuage and I am working in Netbeans. I have been following the some of the sample code in order to achieve some sort of connection to the Test.authorize.net just to see if I was doing it properly. Well so far I can generate the Finger Print, and I can open a connection to the site, but I just get the error ""The following errors have occurred. (13) The merchant login ID or password is invalid or the account is inactive.""

I have checked and recheck that my API Login ID is correct so for starters I do not believe that is the issue. Here is my current code so hopefully someone can point me in the right direction. As always I appreciate any help, concerns, or opinions.

package authorizednet;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.util.*;
import net.authorize.sim.*;
import java.text.SimpleDateFormat;
import java.security.*;
import javax.crypto.*;
import javax.crypto.spec.SecretKeySpec;
import java.net.*;
import javax.net.ssl.HttpsURLConnection;
import java.security.cert.*;

    public static void main(String[] args) throws NoSuchAlgorithmException, InvalidKeyException, MalformedURLException, IOException {
       
        // Payment Variables
        
        String loginID                  = "my Api Login";
        String transactionKey           = "my Transaction Key";
        String amount			= "19.99";
        String description		= "Sample Transaction";
        String label 			= "Submit Payment"; // The is the label on the 'submit' button
        String testMode			= "false";
        URL url			= new URL("https://test.authorize.net/gateway/transact.dll");
        
// Not Sure what this does.
/* If an amount or description were posted to this page, the defaults are overidden

// an invoice is generated using the date and time
        Date myDate = new Date();
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
        String invoice = dateFormat.format(myDate);
    
// a sequence number is randomly generated
        Random generator = new Random();
        int sequence = generator.nextInt(1000);
        
// a timestamp is generated
        long timeStamp = System.currentTimeMillis()/1000;

//This section uses Java Cryptography functions to generate a fingerprint
      
        // First, the Transaction key is converted to a "SecretKey" object
        // Where is kg even being used?
	KeyGenerator kg = KeyGenerator.getInstance("HmacMD5");
	SecretKey key = new SecretKeySpec(transactionKey.getBytes(), "HmacMD5");
        
	// A MAC object is created to generate the hash using the HmacMD5 algorithm
	Mac mac = Mac.getInstance("HmacMD5");
	mac.init(key);
	String inputstring = loginID + "^" + sequence + "^" + timeStamp + "^" + amount + "^";
	byte[] result = mac.doFinal(inputstring.getBytes());
        
	// Convert the result from byte[] to hexadecimal format
	StringBuilder strbuf = new StringBuilder(result.length * 2);
        
	for(int i=0; i< result.length; i++)
            {
		if(((int) result[i] & 0xff) < 0x10){
			strbuf.append("0");
		strbuf.append(Long.toString((int) result[i] & 0xff, 16));
                }
            }
	String fingerprint = strbuf.toString();
// end of fingerprint generation

// printing variables to the screen just to make sure I have even used the response Code 99 tool to confirm 
// I am getting the correct Finger Print.
        
        System.out.println ("Amount: " + amount);
        System.out.println ("timeStamp: " + timeStamp);
        System.out.println ("Sequence: " + sequence);
        System.out.println ("Fingerprint: " + fingerprint);
        
        // Opening connection to the Site
        URLConnection conn = url.openConnection();
        // Post Method
        conn.setDoOutput(true); 
        
        OutputStreamWriter wr;
        wr = new OutputStreamWriter(conn.getOutputStream());
        
        wr.write("x_login"+loginID);
        wr.write("x_amount"+amount);
        wr.write("x_description"+description);
        wr.write("x_invoice_num"+invoice);
        wr.write("x_fp_sequence"+sequence);
        wr.write("x_fp_timestamp"+timeStamp);
        wr.write("x_fp_hash"+fingerprint);
        wr.write("x_test_request"+testMode);
        wr.flush();
        wr.close();
                
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String line;
        while ((line = rd.readLine()) !=null){
            System.out.println(line);
         }
        
        }
}

Thanks in advance,

Brandon

The way you are sending the data in java, not a html form, is AIM, not SIM.

in AIM you send parameter like param1=value1&param2=value2 and there are sample code in java.
