UPS XML Tracking problem

[Douglas Kent]

Hello,
Am attempting to use UPS XML tracking. I'm all set up with login, password, etc, going into the test site at wwwcie.ups.com. I've communicated with their tech support people, and they say my access XML and tracking request XML documents are correct. I can hit the server and get a reply (see below). I have tried URL-encoding the submission and leaving it unencoded. No matter what, get the same reply, here:

  <?xml version="1.0"?><TrackResponse><Response><TransactionReference></TransactionReference><ResponseStatusCode>0</ResponseStatusCode><ResponseStatusDescription>Failure</ResponseStatusDescription><Error><ErrorSeverity>Transient</ErrorSeverity><ErrorCode>20001</ErrorCode><ErrorDescription>General process failure</ErrorDescription></Error></Response></TrackResponse>
  

The word from UPS support is that it's some error on my side, which I can accept, of course, but am out of ideas...Here's my code:

  
import java.net.*;
import javax.net.*;
import javax.net.ssl.*;
import java.io.*;
import java.net.URLEncoder;
 

public class ReadHttpsURL1 {
    static final int HTTPS_PORT = 443;
    public static String enc = "encoding='UTF-8'";
    public static String accessRequest = "<?xml version='1.0'?>< !DOCTYPE AccessRequest SYSTEM 'Request.dtd'><AccessRequest><AccessLicenseNumber>4C0B3A54CA8FA4BC</AccessLicenseNumber><UserId>dglke</UserId><Password>karenke1</Password></AccessRequest>";
    public static String trackRequest = "<?xml version='1.0'?>< !DOCTYPE TrackRequest SYSTEM 'TrackRequest.dtd'><TrackRequest><Request><TransactionReference><CustomerContext/></TransactionReference><RequestAction>Track</RequestAction><RequestOption>none</RequestOption></Request><TrackingNumber>1Z12345E6692804405</TrackingNumber></TrackRequest>";
    
    public static void main(String argv[]) throws Exception {
        if (argv.length != 1) {
            System.out.println("Usage: java <URL> ");
            System.exit(0);
        }
        String encData=null;
        try {
           encData = URLEncoder.encode(accessRequest + trackRequest,"UTF-8");
        } catch (Exception ex){
            System.out.println("Exception: " + ex.getMessage());
        }
        //System.out.println(encData);
        
        //int length = encData.length();
        String combined = accessRequest + trackRequest;
        int length = combined.length();
        // Get a Socket factory
        SocketFactory factory = SSLSocketFactory.getDefault();
        
        // Get Socket from factory
        Socket socket = factory.createSocket(argv[0], HTTPS_PORT);
        
        /*BufferedWriter out = new BufferedWriter(new
                OutputStreamWriter(socket.getOutputStream())); */
        BufferedReader in = new BufferedReader(
                new InputStreamReader(socket.getInputStream())); 
        OutputStream out = socket.getOutputStream();
        String xmlEnc = "application/x-www-form-urlencoded";
        String msg = "POST /ups.app/xml/Track HTTP/1.0\nContent-Length: " + length + "\nContent-Type: " + xmlEnc + "\n\n" + accessRequest + trackRequest;
        out.write(msg.getBytes());
        out.flush();
        
        String line;
        StringBuffer sb = new StringBuffer();
        while((line = in.readLine()) != null) {
            sb.append(line);
        }
        out.close();
        in.close();
        System.out.println(sb.toString());
    }
}

Looking at my post, I see the XML reply from UPS did not completely show, prob due to the long line; here it is again:

  <?xml version="1.0"?><TrackResponse><Response>
<TransactionReference></TransactionReference><ResponseStatusCode>0</ResponseStatusCode>
<ResponseStatusDescription>Failure</ResponseStatusDescription><Error>
<ErrorSeverity>Transient</ErrorSeverity><ErrorCode>20001</ErrorCode>
<ErrorDescription>General process failure</ErrorDescription></Error></Response></TrackResponse>
  

[Douglas Kent]

I see the server filtered out the XML tags:
ResponseStatusCode: 0
ResponseStatusDescription: Failure
ErrorSeverity: Transient
ErrorCode: 20001
ErrorDescription: General process failure

I had read a previous post earlier this year where someone was starting way back from where I am currently. Ulf Dittmer, moderator at the time, seemed to have quite a bit of knowledge of the topic....

[Ulf Dittmer]

And here I am

Looking at what you're sending, it seems that it is not valid XML at all. Unless the UPS Tracking Kit has changed since last I used it, all requests and responses must be proper XML documents. The following are examples I used back then:

<?xml version="1.0"?>
<AccessRequest xml:lang="en-US">
   <AccessLicenseNumber>LICENSENUMBER</AccessLicenseNumber>
   <UserId>USERNAME</UserId>
   <Password>PASSWORD</Password>
</AccessRequest>
 
<?xml version="1.0" encoding="ISO-8859-1"?>
<TrackRequest xml:lang="en-US"> 
    <Request> 
        <TransactionReference> 
            <CustomerContext>sample</CustomerContext> 
            <XpciVersion>1.0001</XpciVersion> 
        </TransactionReference> 
        <RequestAction>Track</RequestAction> 
    </Request> 
    <TrackingNumber>1ZE3820V6841147828</TrackingNumber>
</TrackRequest>

As an aside, if you post XML in these forums, you need to replace all "<" by "&lt;" and ">" by "&gt;", otherwise the software is going to swallow it.

Update after more reading: Or was it valid XML, and all tags in your Java code were removed as well?

Hello Ulf - yes, the XML got filtered out: here's my XML being submitted:

 Access Document:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE AccessRequest SYSTEM "UPSAccessRequest.dtd">
<AccessRequest>
<AccessLicenseNumber>XXXXXXXXXXXX</AccessLicenseNumber>
<UserId>Name</UserId>
<Password>passwd</Password>
</AccessRequest>
 
Track Request Document:
<?xml version = "1.0" encoding = "UTF-8"?>
<!DOCTYPE TrackRequest SYSTEM "TrackRequest.dtd">
<TrackRequest>
<Request>
<TransactionReference>
<CustomerContext/>
</TransactionReference>
<RequestAction>Track</RequestAction>
<RequestOption>none</RequestOption>
</Request>
<TrackingNumber>1Z12345E6692804405</TrackingNumber>
</TrackRequest>   

Thanks in advance for the assist!

[Ulf Dittmer]

Try removing the Doctype declarations.

Also, line endings in HTTP headers consist of a CR/LF combination, and not just of a LF.

[Douglas Kent]

Thanks much. Removing the DOCTYPE declarations did the trick. I read in the HTTP standard that servers are required to accept just a \n, so went with that, working now.

[Ulf Dittmer]

That's good to hear.

Strange about the HTTP linebreaks, though. The HTTP 1.1 spec states "a bare CR or LF MUST NOT be substituted for CRLF within any of the HTTP control structures (such as header fields and multipart boundaries)." in section 3.7.1. It does talk about either CR or LF being acceptable linebreaks in the body, but not the header - which section are you referring to?

[Douglas Kent]

I found the reference - not hte spec itself, but a description - here:
J Marshall
Seems the author finds some wiggle room...


I have been having problems communicating with FedEx XML Tracking service. Do you have any experience with FedEx?

No. UPS is more prevalent here, and it solved our needs.

I have a problem with ups shipping.
When I send request:

<?xml version = \"1.0\" encoding = \"UTF-8\"?> 
		
<AccessRequest xml:lang='en-US'>
<AccessLicenseNumber>license</AccessLicenseNumber>
<UserId>username</UserId>
<Password>password</Password>
</AccessRequest>
<?xml version = \"1.0\" encoding = \"UTF-8\"?> 
	
<ShipmentAcceptRequest>
<Request>
<TransactionReference>
<CustomerContext>guidlikesubstance</CustomerContext>
<XpciVersion>1.0001</XpciVersion>
</TransactionReference>
<RequestAction>ShipAccept</RequestAction>
</Request>
<ShipmentDigest>" . $r->ShipmentDigest . "</ShipmentDigest>
</ShipmentAcceptRequest>

I take a respons : 20001General process failure
Can someone halp me?

[Ulf Dittmer]

What are the backslashes doing there - that's not valid XML.

Also, in line 18, it looks as if something didn't get processed correctly before sending.

[Alexey Rak]

It's a PHP code. Request sending to server looks:
<?xml version = '1.0' encoding = 'UTF-8'?>

<AccessRequest xml:lang='en-US'>
<AccessLicenseNumber>DBA6AB3C96113D48</AccessLicenseNumber>
<UserId>adolphdupre</UserId>
<Password>michael1</Password>
</AccessRequest>
<?xml version = '1.0' encoding = 'UTF-8'?>

<ShipmentAcceptRequest>
<Request>
<TransactionReference>
<CustomerContext>guidlikesubstance</CustomerContext>
<XpciVersion>1.0001</XpciVersion>

</TransactionReference>
<RequestAction>ShipAccept</RequestAction>
</Request>
<ShipmentDigest>xxxxxxxxxxxxxxxxxxxxx</ShipmentDigest>
</ShipmentAcceptRequest>

ShipmentDigest is return correct.

[Alexey Rak]

This is the full respons from server:
<ShipmentConfirmResponse>
<Response>
<TransactionReference>
<CustomerContext>guidlikesubstance</CustomerContext>
<XpciVersion>1.0001</XpciVersion>
</TransactionReference>
<ResponseStatusCode>0</ResponseStatusCode>
<ResponseStatusDescription>Failure</ResponseStatusDescription>
<Error>
<ErrorSeverity>Transient</ErrorSeverity>
<ErrorCode>20001</ErrorCode>
<ErrorDescription>General process failure</ErrorDescription>
</Error>
</Response>
</ShipmentConfirmResponse>
I hope it's help you to find the ansver

[Alexey Rak]

Hi Ulf, I hope you help me, because I have no ideas what's to do.

[Ulf Dittmer]

I haven't used "ShipmentAcceptRequest", so I can't speculate what might be going wrong. Make sure that the request is correct (look at the examples, and read the user documentation). If that doesn't help, check the UPS site for support forums/newsgroups/mailing lists.
