Hi,

  Can anyone help me in this. want to get the XML response from future callout and read it from other method. please look into sample code of mine.





   @future(callout=true)
public static void calloutsample(string name,String phone)
{
 http h=new http();
 tring endPointURL='https://www.endpoint.com';
 Http req = new Http();
 HttpRequest Req=new HttpRequest();
 Req.setHeader('Content-Length', '0');
 Req.setEndpoint(endPointURL);
 Req.setMethod('POST');
 Req.setHeader('Content-Type',text/XML)            // Is this correct, i am sending xml data to external system
 Req.setbody(XMLString);
 httpresponse res=h.send(Req);
 xmlStreamReader reader=res.getxmlStreamReader();
 readresponse(reader);                             //Is this correct. this is the method to read the xml response

public void readresponse(reader)

You can do what you want but you'll need to modify your method definition
  
public static void readResponse(XmlStreamReader reader) {
    // Code
}

Then you just call it the same way you are above.

You setHeader is close but you'll want
  
req.setHeader('Content-Type', 'text/xml');

The content type should be all lower case.

Thanks pcon,

​     here Iam having one more doubt, can we pass colletion of callections in future callout method.

    for example :
     
               @future(callout=true)
                public static void calloutsample(string name,String phone,map<String,map<string,string>> mapvalues)
               
                    (OR)

               @future(callout=true)
                public static void calloutsample(string name,String phone,map<map<string,string>,<String,string>> mapvalues)
    
  In my mapvalues am storing request values and want to save transaction data(request) it into salesforce object but it is not supporting. can you give any idea on this.

You cannot pass anything but primatives and lists/sets of primatives.  What you can do however is convert your Map to a String using JSON.serialize [1] and then once your method starts turn it back into a map with JSON.deserialize [2].
