如何从Java客户端向C＃Web服务发送数据

Question

I am teaching myself Java, i am experienced with C/C++ and C#.

I have a web service in C# which has a function to insert a record into my database, simply a username and password.

    [WebMethod]
    public string InsertNewUser(string username, string password)
    {
        try
        {
            conn.Open();

            string insertQuery = "INSERT INTO Accounts(Username, Password) VALUES ('" + username + "','" + password + "')";

            SqlCommand cmd = new SqlCommand(insertQuery, conn);

            try
            {
                cmd.ExecuteNonQuery();
                conn.Close();
                return "New user added: " + username;
            }
            catch
            {
                return "Error in command execution";
            }
        }
        catch
        {
            return "Error in database connection";
        }
    }

Can anyone tell me if its possible to call this function in a java client side application? if so how do i go about it? Im having trouble finding much online about java connecting to c# web serivces.

At the moment i am using an asmx web service, but thinking about using WCF instead, would this make it easier or harder?

Any help is greatly appreciated.

Thanks

A web service is a web service. That means you can call it from anywhere. Be it from C#, Java or anywhere else. The question is how you are exposing your web service. I recommend exposing it as a REST service, that way it will be accessible from everywhere. There is plenty of information available on the web on how to implement RESTful services. There is even a book, RESTFul .Net, that you can read. Once you implement the REST service, then you access it using HTTP GET, PUT, UPDATE, ETC... from your choice of environment.
