Help with Windows Phone connecting to Salesforce Enterprise API

Hi!

I am trying to call the Enterprise Web Service in Salesforce on my Dev org.
I have the login working correctly, but when I try to make the next call to retrieve I am getting an error.

I was using this great article as a reference:
http://www.developer.com/net/net/salesforce-integration-with-.net-web-services-soap-api-.html?comment=53310-5710

I am trying to do this on a Windows Phone Application through Microsoft Visual Studio 2010 Express for Windows Phone.
This means when I do the 'Add Service References' option and I specify my wsdl that I do not get a wrapper class for setting my metadata URL and the Session ID.
I think my problem is that I do not have my Session ID set in the header section of the Soap Request.
I think I have the metadata URL set properly in the new EndPointAddress that I created.
In Windows Phone I have to make all calls asynchronously, which then makes me specify a callback method.

Here is my endpoint in the Services.ClientConfig file for the initial login call:
<endpoint address="https://login.salesforce.com/services/Soap/c/21.0"
binding="basicHttpBinding" bindingConfiguration="SoapBinding1"
contract="SForceServiceE.Soap" name="SoapE" />

Here is the exception...

Message "No operation available for request {urn:enterprise.soap.sforce.com}retrieve" string
Stack Trace:

Here is the Soap Request...

<s:Header />
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

      </ids>
    </retrieve>
</s:Body>

Here is the Soap Reply...

</soapenv:Envelope>} System.ServiceModel.Channels.Message {System.ServiceModel.Channels.BufferedMessage}

Here is the code I am using...

private void BuildClassFromSalesForce2()
        {
            SForceServiceE.SoapClient myClientR = new SForceServiceE.SoapClient("SoapE");
            myClientR.loginAsync("MyEmail", "MyPasswordMySecurityToken");

myClientR.loginCompleted += new EventHandler<SForceServiceE.loginCompletedEventArgs>(soapLoginCompleted2);

}

private void soapLoginCompleted2(object src, SForceServiceE.loginCompletedEventArgs myArg)
{

            var elements = new List<System.ServiceModel.Channels.BindingElement>();
            elements.Add(new System.ServiceModel.Channels.TextMessageEncodingBindingElement(
                System.ServiceModel.Channels.MessageVersion.Soap11, System.Text.Encoding.UTF8));
            elements.Add(new System.ServiceModel.Channels.HttpsTransportBindingElement());
            System.ServiceModel.Channels.CustomBinding myBinding = new System.ServiceModel.Channels.CustomBinding(elements);

            System.ServiceModel.EndpointAddress myEndPoint = new System.ServiceModel.EndpointAddress(myArg.Result.metadataServerUrl);
            //Where do I set myArg.Result.sessionId?
            //doesn't this need to get into a session header in the Request SOAP message like this?   How do I do this?
            //<soapenv:Header>
            //    <urn:SessionHeader>
            //        <urn:sessionId>xxxxxx</urn:sessionId>
            //    </urn:SessionHeader>
            //</soapenv:Header>

            SForceServiceE.SoapClient myRetrieveClient = new SForceServiceE.SoapClient(myBinding, myEndPoint);

            myRetrieveClient.retrieveCompleted += new EventHandler<SForceServiceE.retrieveCompletedEventArgs>(soapRetrieveCompleted2);
            string[] ids = new string[1];
            ids[0] = "a00E0000000iaEcIAI";
            myRetrieveClient.retrieveAsync("Name", "Game__c", ids, myArg.UserState);
        }

        private void soapRetrieveCompleted2(object src, SForceServiceE.retrieveCompletedEventArgs myArg)
        {
            //It never gets to here. It errors out in SForceServiceE.retrieveResponse
            MessageBox.Show("Retrieve Completed! Count: " + myArg.Result.Length);
        }

Here is where it is erroring out:
public YouTubeSearch.SForceServiceE.retrieveResponse Endretrieve(System.IAsyncResult result) {
                object[] _args = new object[0];
  //Error here!
                YouTubeSearch.SForceServiceE.retrieveResponse _result = ((YouTubeSearch.SForceServiceE.retrieveResponse)(base.EndInvoke("retrieve", _args, result)));
                return _result;
            }

What am I doing wrong?

One of the articles said this error is causing by referencing the Enterprise wsdl, but calling the partner API. Am I doing this?

Thanks!

Its not the namespace in retreive (which is correct), its this part

   <ids>
        <string>a00E0000000iaEcIAI</string>
      </ids>

it should be

   <ids>a00E0000000iaEcIAI</ids>

Have you thought of using the REST API instead ?

Simon,

Here is the value of myArg.Result.metadataServerUrl that I use when creating the Request object after the Login is complete.

"https://na9-api.salesforce.com/services/Soap/m/21.0/00DE0000000Hjbh"

System.ServiceModel.EndpointAddress myEndPoint = new System.ServiceModel.EndpointAddress(myArg.Result.metadataServerUrl);

Is that the URL you wanted to see?

Thanks!

Yes, that's the wrong url, you should be using Result.serverUrl

Thanks! I think I am farther now with serverUrl instead of metadataServerUrl.

I am now getting this error
Invalid Session ID found in SessionHeader: Illegal Session

I think this brings me back a question in my original post.
Where do I set myArg.Result.sessionId?
Doesn't this need to get into a session header in the Request SOAP message like this?   How do I do this?   This is very much a c# .net question I know.

After adding in a Soap header with the SessionID I am still getting a message that: INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session

I was able to add to add the message header for sessionID with code like this...

System.ServiceModel.Channels.AddressHeader addressHeader1 =
                   System.ServiceModel.Channels.AddressHeader.CreateAddressHeader( "sessionId", "", myArg.Result.sessionId);
System.ServiceModel.Channels.AddressHeader[] addressHeaders1 = new System.ServiceModel.Channels.AddressHeader[1] { addressHeader1};
Uri myUri = new Uri(myArg.Result.serverUrl);
System.ServiceModel.EndpointAddress myEndPoint = new System.ServiceModel.EndpointAddress(myUri, addressHeaders1);

Here is my Request....

-       Request   {<?xml version="1.0" encoding="utf-16"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">

Help? Is my SessionID not formatted properly?

Does it have to look like this instead?
//<soapenv:Header>
            //    <urn:SessionHeader>
            //        <urn:sessionId>xxxxxx</urn:sessionId>

Yes, your session header is wrong, and it should be as you state at the end of the post.

I really appreciate your help Simon!

I can now make my request look a lot better by formatting an object instead of a string, but I stil get the same 'Invalid Session ID' error.

Here is my new code:
SessionHeader myHeader = new SessionHeader();
            myHeader.sessionId = myArg.Result.sessionId;
            System.ServiceModel.Channels.AddressHeader addressHeader1 =
                   System.ServiceModel.Channels.AddressHeader.CreateAddressHeader("SessionHeader", "", myHeader);

Here is my new request object:
+       Request   {<?xml version="1.0" encoding="utf-16"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header>
    <SessionHeader xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
      <sessionId xmlns="http://schemas.datacontract.org/2004/07/YouTubeSearch">00DE0000000Hjbh!ARkAQNp45M8a5FG3x.SoookJIuDbIxQzUcFECgbJ8MFsa3ZaU417HQXHWtWYNrtoDjhbP9qojWDwxpQ45Zon.L4_Xw1FHTd7</sessionId>
    </SessionHeader>
</s:Header>
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <retrieve xmlns="urn:enterprise.soap.sforce.com">
      <fieldList>Name</fieldList>
      <sObjectType>Game__c</sObjectType>
      <ids>
        <string>a00E0000000iaEcIAI</string>
      </ids>
    </retrieve>
</s:Body>
</s:Envelope>}   System.ServiceModel.Channels.Message {System.ServiceModel.Dispatcher.OperationFormatter.OperationFormatterMessage}

Do I have to some how get the urn: in front of the SessionHeader and SessionId values?
Is the "xmlns" causing a problem?

Thanks!

The SessionHeader and sessionId elements are both in the wrong namespace, the exact prefix doesn't matter, but the URI does, it needs to look something like

<SessionHeader xmlns"urn:enterprise.soap.sforce.com"> <sessionId>some sid</sessionId> </SessionHeader>

or

<p:SessionHeader xmlns:p="urn:enterprise.soap.sforce.com"> <p:sessionId>some sid</sessionId> </p:SessionHeader>

I have been able to manipulate the SessionHeader xmlns values with the DataContract and DataMember values from System.Runtime.Serialization.

I'm sorry to say this, but..

Here is my new error:

<faultcode>soapenv:Client</faultcode>
      <faultstring>Unexpected element {urn:enterprise.soap.sforce.com}string during simple type deserialization</faultstring>

I'm pretty sure this error is referring to the "urn:enterprise.." after the <retrieve.
I can tell this because if I change the urn:enterprise in the SessionHeader line to something random I still
get the same error.

My Request:

+       Request   {<?xml version="1.0" encoding="utf-16"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">

I hope somebody else will learn from my pain. :)

Simon,

I ( we ) got it!

Thank you for all your help!! I have learned a ton.

I switched to using the queryAsync to work around the problem with the <ids> not being on the same line.   If the 'MessageHeaderArrayAttribute' were available in the Windows Phone .NET environment I would have been able to make it work. But anyway, it works now!

string qry;
            qry = @"SELECT ID, Name, Phone, Email, Department FROM User";

            myRetrieveClient.queryCompleted += new EventHandler<SForceServiceE.queryCompletedEventArgs>(soapQueryCompleted2);
            myRetrieveClient.queryAsync(qry, myArg.UserState);

Thanks!
