serversocket
 
Bom dia!
to começando com java mas no entanto já tenho uma certa experiência com php. to tentando criar um serversocket com java para receber dados de umgps modelo tk102 , fiz a classe abaixo que por sinal esta "funcionando" euemulei o modelo dele no meu smart e ele fez o que tinha que fazer leu e imprimiu em tela os logs, entretanto quando eu coloco o gps pra conectar ele nao conect. sei que ele esta funcionando pois em um forum na net um cara meforneceu o ip do server dele e nele conectou. alguem pode me ajudar ?



import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Track {

public static void main(String[] args) {

//Declaro o ServerSocket
ServerSocket serv = null;

//Declaro o Socket de comunicação
Socket s = null;

//Declaro o leitor para a entrada de dados
BufferedReader entrada = null;

while (true) {

try {

//Cria o ServerSocket na porta 11000 se estiver disponível
serv = new ServerSocket(11000);

//Aguarda uma conexão na porta especificada e cria retorna o socket que irá comunicar com o cliente
s = serv.accept();

//Cria um BufferedReader para o canal da stream de entrada de dados do socket s
entrada = new BufferedReader(new InputStreamReader(s.getInputStream()));

//Aguarda por algum dado e imprime a linha recebida quando recebe
System.out.println(entrada.readLine());

//trata possíveis excessões de input/output. Note que as excessões são as mesmas utilizadas para as classes de java.io
} catch (IOException e) {

//Imprime uma notificação na saída padrão caso hajaalgo errado.
System.out.println("Algum problema ocorreu para criar ou receber o socket.");

} finally {

try {

//Encerro o socket de comunicação
s.close();

//Encerro o ServerSocket
serv.close();

} catch (IOException e) {
}
}
}

Hallo!

Das ist ein sehr interessantes Schreiben, was Sie da veroeffentlichen.
Leider spreche ich Ihre Sprache nicht, genau so, wie Sie vermutlich meine
nicht sprechen. Daher ist es sinnvoll, Schreiben in einer der Gruppe
angepassten Sprache zu veroeffentlichen.

Liebe Gruesse,
Joerg

Good morning!
to starting with java but Nevertheless I have some experience with php. Trying to create a ServerSocket with java to get data from the GPS model TK102, did the class below That by the way this "working" I emulei the model of it on my smart and he did what he HAD to read on screen and printed logs , However when i put the gps to connect it does not conect. I know he is working as a forum on the net a guy Gave me the ip of the server and connected it hin. Can someone help me?

A ServerSocket is used when you want to be the server. A Socket is used
when you want to connect to a server. Is the GPS running a server?

Actually, the code you show is riddled with bugs and potential bugs.

I don't know what you mean by "working", but it isn't what I mean.

Gave you the IP address of what server? How does another server demonstrate
the correctness of your code?

First, thank you for providing such a complete example. Not everyone does.
Those folks should take heed of

http://sscce.org/

You do tend to comment excessively, making note of things the code itself
already documents. For example:

//Declaro o ServerSocket
ServerSocket serv = null;

Well, duh! Comments should be helpful, not silly. They should express what the
code does not already make crystal clear.

I find the style of many consecutive blank lines at random points in the
source to be disconcerting at best. What is it intended to communicate?

Also, your variable names are too terse. 's' and 'serv' are not as good
variable names as 'socket' and 'serverSocket'.

serverSocket = new ServerSocket(11000);

The value '11000' should be declared as a constant variable member, not
embedded deep in the code like this, an antipattern called "magic values".

try
{
s.close();
serv.close();
}
catch (IOException e)
{
}

Don't ever ignore exceptions like that! At an absolute minimum you must log them.

Note that if 's.close();' throws an exception, 'serv.close();' will not
execute. There's room for a bug there, in theory. (In practice I've never
heard of such a 'close()' call failing, but it could, I suppose.)

Furthermore, you coded these resource variables in such a way as to risk a
'NullPointerException' ("NPE"). This is a common consequence of initializing
resource variables to 'null' and ignoring the concomitant responsibility to
check for 'null' before calling methods on them. That's bad coding, for sure.

I find it safer to declare the variables 'final' and not initialize them to
'null' but to the desired resource reference in a separate 'try...catch'
block. That way you don't have to check for 'null' when you 'close()' them.
Doing what you did is begging for bugs.

You initialize the server socket every time through the loop. That is not
normal. You shouldn't create a new server socket every time you want to make a
connection; you should reuse the server socket and get a new regular socket
for each connection.

You should limit the scope of 'entrada' to the block that uses it. Declaring
variables with too wide a scope is an invitation for bugs, and an impediment
to the garbage collector.

I provide a rewrite taking these hints into account. As an exercise, you
should convert all the static methods except 'main()' into instance methods. I
gave you a head start.

The code compiles but I haven't run it.

I made a mistake in the 'serveConnections()' method, arguably. Or maybe it
isn't a mistake.

What do you think; is it a mistake or not?

I've found a set of variations on a sort-of spec for the TK-102 which
don't shed a lot of light. The thing is a vehicle or person tracker:
you're meant to stick a SIM into it and either interrogate it via SMS or
set it up to send you an SMS at configurable intervals to say where it
is. It also seems to have a microphone that can be used to listen in to
what's happening near it.

It appears that you can also talk to it via its USB socket for
configuration, etc. This assumes you'll use something like a Windows box
running Hyperterminal or a Linux system running minicom or Kermit. I
gather from this that the USB connection must be a serial connection,
which Java does not do without JNI, though I suppose you could use a
socket connection to talk to a TCP:serial converter of some sort.

There is some talk about configuring it with an IPV4 IP, but I frankly
don't understand this unless you can piggyback a TCP session onto GPRS
and/or via an SMS stream and so get to it that way.

In any case it looks very much as though the TK-102 wants to be the
server, so if it can be reached over a socket connection, it looks like
the OP should be using a Socket rather than a ServerSocket to talk to it.

Re: serversocket
 
Well, first I thank you for the answer, and guidelines apply to my learning!
the customer is a good model tk 102 gps, if not I engando communicates via tcp.
What struck me is that the same code works on a smartphone, I used the tracker to emulate mylive sending data tk 102
