Ho realizzato un semplicissima applicazione CLIENT - SERVER
Solo che il server ed il client non comunicano per niente...
Qualcuno sa dirmi dove sbaglio?
------------------------------------------------- SERVER
import java.io.*;
import java.net.*;
class TCPServer{
public static void main (String argv[]) throws Exception{
String clientSentence;
String capitalizedSentence;
ServerSocket welcomeSocket = new ServerSocket(5700);
while(true){
Socket connectionSocket=welcomeSocket.accept();
BufferedReader inFromClient=new BufferedReader(new InputStreamReader(connectionSocket.getInputStream( )));
DataOutputStream outToClient= new DataOutputStream(connectionSocket.getOutputStream( ));
clientSentence = inFromClient.readLine();
capitalizedSentence=clientSentence.toUpperCase() + '\n';
outToClient.writeBytes(capitalizedSentence);
System.out.print(clientSentence);
}
}
}
---------------------------------- CLIENT
import java.io.*;
import java.net.*;
class TCPClient {
public static void main (String argv[]) throws Exception
{
String sentence;
String modifiedSentence;
BufferedReader inFromUser=
new BufferedReader(new InputStreamReader(System.in));
Socket clientSocket = new Socket ("127.0.0.1",5700);
DataOutputStream outToServer=
new DataOutputStream(clientSocket.getOutputStream());
BufferedReader inFromServer=new BufferedReader(new InputStreamReader(
clientSocket.getInputStream()));
sentence = inFromUser.readLine();
outToServer.writeBytes(sentence + '\n');
modifiedSentence = inFromServer.readLine();
System.out.println("FROM SERVER:" + modifiedSentence);
clientSocket.close();
}
}
