POCalling an object from another class (java, javafx)

copied!<p>I'm already working on this for weeks to get it working but without success. I'm using Javafx and java for implementing a small chat programm using the smack API (xmpp). The problem is how to get the received messages from java to javafx. The code below is actualy working when I have variable with a static string like "test message" and calling postMessage in java to send it to javafx. But how do I get another object (MessageListener) from java calling postMessage?</p> <pre><code>public class Java_callback implements RunnableFuture { FXListener listener; public String testmsg; public Java_callback(FXListener listener) { this.listener = listener; } @Override public void run() throws Exception { postMessage(testmsg); } public void postMessage(final String msg) { Entry.deferAction(new Runnable() { @Override public void run() { listener.callback(msg); } }); } } </code></pre> <p>Here the code for processing the message. This part somehow need to call postMessage from the code above.</p> <pre><code> public void xmpp_create_chat(String msg) { ChatManager chatmanager = connection.getChatManager(); Chat newChat = chatmanager.createChat("admin@unfc", new MessageListener() { @Override public void processMessage(Chat chat, Message message) { //msgArray.add( new String("Received message: " + message.getBody()) ); //msg_return = "blabla"; //java_callback.postMessage(msg_return); //test.postMessage(message.getBody()); //System.out.println("Received message: " + message); } }); </code></pre>
