Attempt to de-reference a null object from Rest API class.

Hi Guys, 

I have written a simple REST class to connect two SF orgs (lets say A and B), 

in A, i have created remote site 'Login.salesforce.com' and wrote below class, 
  
@RestResource(urlMapping='/createNewAccountUsingRestAPI/*')
global with sharing class RESTCreateNewAccount{

    @HttpPost
    global static string createAccountRecord(String name) {
     string succError;
     account acc = new account();
     acc.name = name;       
     insert acc;
     acc.accountsource = 'Other';
     update acc;
     succError = 'New account has been created. Account Record id is:'+acc.id;
     return succError;
    }
  
    @httpput
    global static string updateAccountRecord(String name) {
       string returnmessage = 'Account are updated successfully';
       List<account> accupdateList = [select name,id,AccountSource from account where name =: name];
       for(account acc : accupdateList){
           acc.AccountSource = 'Web' ;
           returnmessage = returnmessage +acc.id;
       }
       try{
         update accupdateList;
       }
       catch(exception ex){
         returnmessage = ex.getmessage();
       }
       return returnmessage ;
    }           
}

in Org B, i have written Below class,
  
public class RestAPIcalloutExample{

   Public void loginToOtherOrgAndCreaetNewAccount(){
        /*Login to Other Salesforce Org to grab session id - begin*/
        HTTP h1 = new HTTP();
        HttpRequest request = new HttpRequest();       
        request.setEndpoint('https://login.salesforce.com/services/Soap/u/22.0');
        request.setMethod('POST');
        request.setHeader('Content-Type', 'text/xml;charset=UTF-8');
        request.setHeader('SOAPAction', '""');
        request.setTimeout(60000);
        request.setBody('<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"><Header/><Body><login xmlns="urn:partner.soap.sforce.com"><username>' + 'vigneshwaranl@hotmail.com'+ '</username><password>' +'makil1234'+ '</password></login></Body></Envelope>');
        String SERVER_URL;
        String SESSION_ID;
        HTTPResponse loginResponse = h1.send(request);     
        Dom.Document doc = loginResponse.getBodyDocument();
        Dom.XMLNode receivedXml= doc.getRootElement();
        SESSION_ID = receivedXml.getChildElement('Body', 'http://schemas.xmlsoap.org/soap/envelope/').getChildElement('loginResponse', 'urn:partner.soap.sforce.com').getChildElement('result','urn:partner.soap.sforce.com').getChildElement('sessionId','urn:partner.soap.sforce.com') .getText();      
        system.debug('***session id'+SESSION_ID); 
        /*Login to Other salesforce Org to grab session id - finish*/
      
        /* Send https request to the custom REST API defined in other org that has urlmapping as 'createNewAccountUsingRestAPI' -begin*/
        HTTP h2 = new HTTP();
        HttpRequest request2CreateAccount = new HttpRequest();
        request2CreateAccount.setMethod('POST');
        request2CreateAccount.setHeader('Content-Type', 'application/json;charset=UTF-8');
        request2CreateAccount.setHeader('Accept', 'application/json');
        request2CreateAccount.setHeader('SOAPAction', '""');
        request2CreateAccount.setbody('{"name":"Cloudforce4u Technologies Ltd"}');
            request2CreateAccount.setEndpoint('https://ap1.salesforce.com/services/apexrest/createNewAccountUsingRestAPI');
        request2CreateAccount.setHeader('Authorization', 'OAuth '+SESSION_ID);             
        HTTPResponse resppnceFromOtherSFOrg = h2.send(request2CreateAccount);
        /* Send https request to the custom REST API defined in other org that hass urlmapping as updateaccountrec - finish*/
        system.debug('**-Output-**'+resppnceFromOtherSFOrg.getbody());
   } 
 }

i tried to run this from Dev Console from Org B, its showing 'de-reference a null object' Error.. What is the mistake here.? 

Thanks, 
Vignesh
