# Codename Sockets Library

This library was started as an attempt to add sockets support to Codename One.  I have so far created native interfaces for iOS, Android, Blackberry, JavaSE and J2ME.

## Installation

Install through Codename One Settings > Extensions.  Or manually install with following steps:

1. Copy the [CN1Sockets.cn1lib](bin/CN1Sockets.cn1lib) library into your application's `lib` directory.

2. Right click on your project's icon in the Netbeans project explorer, and select "Refresh Libs"

## Usage Example

~~~~

import ca.weblite.codename1.net.Socket;

// .. rest of imports

// … your application's main class

    public void start(){

        lbl = new Label("Result here");

        Form hi = new Form("Socket Tester");

        Button btn = new Button("Run Test");

        btn.addActionListener(new ActionListener(){

            public void actionPerformed(ActionEvent evt) {

                Display.getInstance().callSerially(new Runnable(){

                    public void run() {

                        runSocketTests();

                    }

                    

                });

            }

            

        });

        

        hi.addComponent(btn);

        hi.addComponent(lbl);

        hi.show();

    }

    

    

    public void runSocketTests(){

        try {

            if ( Socket.isSocketSupported() ){

                Socket sock = new Socket("example.com", 80);

                sock.getOutputStream().write("GET / HTTP/1.0\r\nHost: example.com\r\n\r\n".getBytes());

                String result = Util.readToString(sock.getInputStream());

                    // NOTE:  Util.readToString() closes the input stream automatically.

                    // Don't use it if you need to keep the socket open.  Use

                    // another mechanism to read the stream.

                lbl.setText(result);

                //sock.close();

                Log.p(result);

            } else {

                lbl.setText("Sockets not supported");

                Log.p("Sockets not supported");

            }

        } catch ( Exception ex){

            Log.p("We have an error");

            Log.e(ex);

            

        }

    }

// …

## To Do

1. Try out the J2ME and Blackberry ports.  They are there but I have never tested them so they may need some tweaking.

2. Stress test.
