Hi,

I am trying to get one webservice methdos from one org to another org without any login details.

My webservice :

global class testWebservice
{  
     
      webservice static string test()
      {
          return 'test-test';
      }   
 
}

from another org I am calling :

 HttpRequest req = new HttpRequest();
        HttpResponse res = new HttpResponse();
        Http http = new Http();
 
// I have created site and given public access to testWebservice class



req.setEndpoint('https://harshalatest-developer-edition.na7.force.com/mysite/services/Soap/class/testWebservice/test');
        
        req.setMethod('POST');       
        req.setHeader('SOAPAction','');
        req.setHeader('Content-Type', 'text/xml;charset=UTF-8');       
        req.setCompressed(true); // otherwise we hit a limit of 32000
 
        try 
        {
            res = http.send(req);            
            System.debug('In sendRequest BODY: '+res.getBody());
            System.debug('STATUS:'+res.getStatus());
            System.debug('STATUS_CODE:'+res.getStatusCode());
        } catch(System.CalloutException e)
        {
            System.debug('Callout error: '+ e);
            System.debug(res.toString());
        }
