Keep on getting Login failed for user 'sa' despite using correct login credentials

I am simply trying to test my connection with SQL Server 2008 as follows:

Java Code:

public class ForJDBC {

   
    public static void main(String[] args) {
        
        
      
        
        try{
        
        Connection conn = DriverManager.getConnection("jdbc:http://sqlserver10.11.0.225:1433;databaseName=Alerts;user=sa;password=mypassword");
        
        if(conn != null){
            
            System.out.println("Connection is Successfull");
        }
        
        }
        catch(SQLException ex){
            
           ex.printStackTrace();
        }
        
        
        
        
    }
}

But I keep on getting the following exception:

When I connect to MySQL 5.5, it works fine.

Troubleshooting Steps I have followed:

1) Tried Logging with the "sa" user name and password within the SQL Server Management Console



using SQL Server Management studio

2) I have sqljdbc4.jar in my Source Package folder of Netbeans 7.4

3) Updated to Java 8
