when i run that (see the code below) I get this error. Class1 cannot be serialized because it does not have a parameterless constructor.

public class Class1 : WebService
{
    // default constructor
    public Class1(){}

    // overloaded constructor
    public Class1(string s1, string s2, string s3)
    {  
    // ...your code here
    }

}
