Hi Raju,

You can perform callout as 
public class HttpCalloutSample {

// Pass in the endpoint to be used using the string url
  public String getContent(String url) {

// Instantiate a new http object
    Http h = new Http();

// Instantiate a new HTTP request, specify the method (GET) as well as the endpoint
    HttpRequest req = new HttpRequest();
    req.setEndpoint(url);
    req.setMethod('GET');

// Send the request, and return a response
    HttpResponse res = h.send(req);
    return res.getBody();
  }
}
Please go through http://www.salesforce.com/us/developer/docs/apexcode/index_Left.htm#StartTopic=Content/apex_callouts.htm for more information.

Thanks,
N.J

There in normal or abnormal Apex. Callout is basically use a set of Apex classes used to callout to external system. There are twoways of callout Rest and Soap.

Rest class include: HttpRequest, HttpResponse, Http etc.
Soap are defined by parsing wsdl in Apex. A simple caalout has already been given in post above.
