How to set session Id in Apex (Salesforce to Salesforce Integration via SOAP)?

Question

I have created a webservice class in Salesforce Org B (destination).

The purpose of this webservice is to accept values and create a custom object record in Org B.

1. I generated partner WSDL from Org B and imported into in my Org A (my Source Salesforce Org).

2. I generated WSDL for my webservice class from Org B and again imported into my Org A (it created two classes)

3. After adding the remote site settings I wanted to testdrive sending data from Org A to Org B.

This is the code snippet that I tried it in anon apex.

partnerSoapSforceCom.Soap p = new partnerSoapSforceCom.Soap();
String uname = 'UNAME';
String pwd = 'PWD+TOKEN';
partnerSoapSforceCom.LoginResult e = p.login(uname,pwd);
System.debug('The result of the login call is => '+e);
System.debug('ServerURL = '+e.serverURL);//Line 1
System.debug('Session Id = '+e.SessionId);//Line 2



soapSforceComSchemasClassCreateRec.rec rm = new soapSforceComSchemasClassCreateRec.rec();

rm.documentdate = '2016-02-25 00:00:00';
rm.documentid = '1';
rm.Name = 'Test';
soapSforceComSchemasClassCreateRec.rec rd1 = new soapSforceComSchemasClassCreateRec.rec();
rd1.createDocument(rm);

I am able to make a successful handshake and get serverurl and sessionId (Line 1 & Line 2).

After authentication, I am trying to invoke the actual webservice method for creating record and I am getting the following error as below.

I believe it is because I have not set the session Id which I received from Line 2 during the actual invocation.

Can someone tell me how do I actually set the session Id in my request ?

Answer 1

Use loginResult.sessionid for sessionid

partnerSoapSforceCom.Soap obj = new partnerSoapSforceCom.Soap();
partnerSoapSforceCom.LoginResult loginResult = obj.login('[email protected]', 'Password');
obj.SessionHeader = new partnerSoapSforceCom.SessionHeader_element();
obj.endpoint_x =loginResult.ServerUrl;
obj.Sessionheader.sessionid = loginResult.sessionid;
