Facade or Adapter design pattern

We have the following scenario.

A web URL is exposed and we want to get and post requests to it in order to receive information about a user.

e.g. http://example.com/getBalance?userid=1234&username=example

The plan is to create a class that will have a number of methods that will be like

public class ClassA {
  public int getBalance(string userId, string userName){
     URL url= new URL("http://www.yahoo.com/");
    URLConnection yc = url.openConnection();
    BufferedReader in = new BufferedReader(
                            new InputStreamReader(
                            yc.getInputStream()));
    return in.readLine()) 
  }
  ...
}

And then use this class to make the http calls. 

ClassA a = new Class();
a.getBalance(tdks123, name1);

Is this scenario a Facade pattern or an adapter pattern?

This is actually Session Facade design pattern ( J2EE design patterns). and in plain old patterns it is subset of Facade pattern.

Session facade pattern is used when :

You want to expose business components and services to remote clients.

RESTful web service is good example of session facade.
