Sending String to a Terminal

Here is what Im trying to do:

I created an app that creates special queries. How can I have my java app automatically send those created queries directly to a terminal window? or it can directly connect to the ftp server and send the query and return output. Is this possible?

It's just a simple client server application.
You need a "Socket" Connection between the 2 terminals.

You will need to use the classes:
java.net.ServerSocket
java.net.Socket
To establish the client-server connection

You'll also need the classes:
java.io.ObjectInputStream
java.io.ObjectOutputStream
to transfer data between both terminals

I've seen an example to create a simple messenger using simple TCP/IP connection between 2 computers and the Client-Server approach for some reason. try searching the web, I guess you'll find more useful samples

To use this do I need to mess with router settings? or is it good to go as is?

Not necessarily. It depends on whether your current configuration, I don't think I can answer this question for you. But a simple test should do it :)

Here is the code im working with right now: (Im leaving the serverName blank for security purposes)

Code:

---

            String        serverName = "";
    int        portNumber = 22;

    Socket        server = null;
   
    try
    {
    server = new Socket(serverName, portNumber);

   
     
    InputStream        input = server.getInputStream();
   
   
   
    int                byteCount;
    byte                inputBuffer[] = new byte[1024];
       
    while ((byteCount =  input.read(inputBuffer, 0, 1024)) != -1)
    {
      String        stuff = new String(inputBuffer, 0, 0, byteCount);
     
          System.out.println("Received: " + stuff);
 
    }
    } // end try
    catch (Exception e) { System.out.println(e.toString()); }
       
    System.out.println("done");

And here is the output im getting:

Quote:

---

Received: SSH-2.0-OpenSSH_3.9p1

done

---

and it takes about 2 minutes to go from the first line to 'done'. Any idea on whats going on? How can I send a command? I need to login some how too, not sure how to do that. Thanks

Code:

int portNumber = 22;

Are you sure this port number is not being used by another service? this might be the reason for a slow data transfer

Code:

new String(inputBuffer, 0, 0, byteCount);

Don't use deprecated methods

Code:

---

System.out.println("Received: " + stuff);

If more than 1 KB is being read, the word "Received" will be printed over and over

try using the following code:

Code:

---

            ObjectInputStream str=new ObjectInputStream(input);
            System.out.println(str.readUTF());
