The Code Sample 2 shows the implementation of Socket Connection:
Socket Connection
import javax.microedition.io.*;
import java.io.*;
import javax.microedition.midlet.*;
….
try {
//open the connection and io streams
sc =
(SocketConnection)Connector.open("socket://www.myserver.com
:8080", Connector.READ_WRITE, true);
is = sc[i].openInputStream();
os = sc[i].openOutputStream();
} catch (Exception ex) {
closeAllStreams();
System.out.println("Open Failed: " +
ex.getMessage());
}
}
if (os != null && is != null)
{
try
{
os.write(someString.getBytes()); //write
some data to server
int bytes_read = 0;
int offset = 0;
int bytes_left = BUFFER_SIZE;
//read data from server until done
do
{
bytes_read = is.read(buffer, offset,
bytes_left);
if (bytes_read > 0)
{
= bytes_read;
bytes_left -= bytes_read;
}
