Hi All,

I m facing a problem on one of our java interface with Salesforce. This interface integrates contacts in Salesforce from an input file. The process use MultiThreading for executing some tasks.
When the interface is runned it inserts some records and generates an INVALID_SESSION_ID error.

Below the entire java error that we have:

AxisFault
 faultCode: {urn:fault.enterprise.soap.sforce.com}INVALID_SESSION_ID
 faultSubcode:
 faultString: INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session. Session not found, missing session key: 00DR0000000F5jb!ARYAQCGEvJx62RSz.K3fEQPT6Dx6ufkHD8cqw9pKOr5uIDme2MgT9_Kinf3x_OL6pKgcrXJYFK.6V7hMOo4cNRKV1dOpQqo3

The  Code :

 SoapBindingStub   sfdc = (SoapBindingStub) new SforceServiceLocator().getSoap();
     loginResult = sfdc.login(username,password);
     sfdc._setProperty(SoapBindingStub.ENDPOINT_ADDRESS_PROPERTY, loginResult.getServerUrl());
     SessionHeader sh = new SessionHeader();
     sh.setSessionId(loginResult.getSessionId());
     configObj.getsfdcAPIDtls().setServerURL(loginResult.getServerUrl());
     configObj.getsfdcAPIDtls().setSessionId(loginResult.getSessionId());
     sfdc.setHeader(new SforceServiceLocator().getServiceName().getNamespaceURI(),"SessionHeader", sh);
   
     return sfdc;  
  

            String externalID= configObj.getsfdcAPIDtls().getExternalID();

         upsertResult = binding.upsert(externalID,upsertArr);

Thanks,

Siva.
