Chatting from java
  
 
Posted: Jan 26, 2014

Hello,
I have been working on an application built in java that creates a chat interface and connects to a ChatScript server(local).
I am still learning Java and ChatScript so I know im error prone.

the program should connect to the local server, send whatever the user types and recieve the output to display.

The following code I have written is suppose to push a message to the server and recieve the volley in return.

if(ae.getActionCommand().equals("Send")) {
   Chat c = new Chat();
   
   // Push Message
   c.setFrom(login);
   c.setTo(bot);
   c.setMessage(chatInput.getText());
   chatDisplay.setText(chatDisplay.getText() + c.getFrom() + ": " + c.getMessage() + "n");
   
   
   // Open Chat Script and send the message
   try {    
    Process p= Runtime.getRuntime().exec(path + args + c.get());
    p.waitFor();
    InputStream in = p.getInputStream();
    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    baos.write(in.read())
    c.set(bot, login,new String(baos.toByteArray()) );
    
    
     
   } catch (Exception e) {
    e.printStackTrace();
   }
   
   //Display output
   //c.set(bot, login, "Hello"); //dummy chat   
   chatDisplay.setText(chatDisplay.getText() + c.getFrom() + ":" + c.getMessage() + "n");
   
   //clear the input {write code}
  }
 } 

any suggestions or advice?

Process p= Runtime.getRuntime().exec(path + args + c.get());
 
Not being a java expert, it looks to me like you are merely executing ChatScript and trying to put the chat on a command line to it. Doesn’t work that way.  If you were trying to communicate with a local server, you would be opening a socket, connecting to localhost:1024 and sending and receiving the socket data then closing it

What Bruce said is essentially correct - here is code to connect to the chatbot server from java and send/receive a text…

/** class is instantiated, then initialized, call processInput(message) **/

public class ChatScriptBot implements Bot {

 char nullChar = (char) 0;
        String userName = "Jerry"; // or take as input
 
 @Override
 public String processInput(String input) {
  return doMessage(default+nullChar+nullChar+input+nullChar);
 }

 private String doMessage(String mess)
 {
  Socket echoSocket;
  String resp = "";
  
  try {
   echoSocket = new Socket("localhost", 3333);
   PrintWriter out = new PrintWriter(echoSocket.getOutputStream(),
     true);
   BufferedReader in = new BufferedReader(new InputStreamReader(
     echoSocket.getInputStream()));
   out.println(mess);
   resp = in.readLine();
   echoSocket.close();
  } catch (IOException e) {
   e.printStackTrace();
   System.out.println("Error: " + e.getMessage());
  }

  return resp;
  
 }
 @Override
 public void init(HashMap<String, String> args) {
  System.out.println("ChatScript Bot init()...");
  System.out.println("got back:" + doMessage(nullChar+"1"+nullChar+nullChar));
  System.out.println("now starting conversation..." + doMessage(userName+nullChar+nullChar+nullChar));
  System.out.println("conversation started with default bot as " + userName);
 }

 @Override
 public String getBotType() {
  // TODO Auto-generated method stub
  return "ChatSCript";
 }

} 

Run the server as described in the server manual, substitute the right port number.  Hope this helps.  The tricky part is the null termination - java strings are not null terminated so you have to do it manually.

i get error at this line:
  return doMessage(default+nullChar+nullChar+input+nullChar);
does default needs to be removed?

no, you need to define default as the user you are connecting as.  I think the sample I posted inherited that variable from it’s parent, so it isn’t defined in that snippet?

Correct! Works perfectly now. Thanks alot Todd.
Did you had any luck with using Chatscript as library with JNI or Swig?

I have, yes.  I’m assuming you are referring to - http://vinterstitial.blogspot.com/2014/05/a-swig-of-chatbot-making-unity-chatter.html?

I haven’t used the java JNI versions extensively, but it passed my tests when I was checking that alternative.  You can find the latest swig stuff for java on my GitHub - https://github.com/tkuebler/ChatScriptBrains

I have written a Apache Camel component to interact with the BOTS. Initial version can be checked out from git hub.

Have you bumped up an old thread to say this for a reason?
