 |
|
Hello!
I've got problems sending strings to a small test-program on my Linux PC from my PSP using LUA socket functions.
on my PSP i've got this code:
| Code: |
socket = Socket.connect("192.168.1.4", 4444)
while not socket:isConnected() do System.sleep(100) end |
and then this :
| Code: |
while true do
socket:send("hello")
screen:print(20,100,"message sent", green)
screen.flip()
System.sleep(1000)
if Controls.read():cross() then
break end
end
screen.waitVblankStart(120)
end
|
on my pc I've got a small java program running sockets:
| Code: |
import java.net.*;
import java.io.*;
class pspConnect{
public static void main(String[] args) throws IOException
{
ServerSocket serverSocket = null;
// tries to open socket and exits with error if failed
try
{
serverSocket = new ServerSocket(4444, 5 );
}catch (IOException e) {
System.err.println("could not listen on port: 4444");
System.exit(-1);
}
//waits for connect and prints "connected" if successful
Socket incoming = serverSocket.accept();
if (incoming.isConnected())
{
System.out.println("connected");
}
BufferedReader in = new BufferedReader( new InputStreamReader( incoming.getInputStream()));
//spits out anything that comes through
while(true)
{
System.out.println(in.readLine());
}
}
}
|
It works as far as to getting a "connected" on my console output on my PC
I've also written this small client and run succesfully it on a separate computer:
| Code: |
import java.net.*;
import java.io.*;
class pspConnectClient{
public static void main(String[] args) throws Exception
{
Socket socket;
socket = new Socket("192.168.1.4", 4444);
if(socket.isConnected())
{
System.out.println("I'm connected");
}
String message;
System.out.print("\ttype something");
message = Keyboard.readString();
PrintStream send = new PrintStream(socket.getOutputStream());
while (true)
{
send.println(message);
}
}
}
|
My server spits out anything I write into this small client, so Java -> Java works OK atleast
I've also tested the psp connecting to Hercules (a tcp testing software) through wine on my linux pc and I receive the "hello" string as expected.
which means that the PSP is in fact communicating with my PC (also proven by me receiving the "connected" message from the java-program).
So why oh why can I not send a string from my PSP to my small socket-program?
thx for help in advance
