Hi everyone,
I’m trying to manage a light behaviour in correlation with a BPMN process diagram. I’ve implemented a Java Server which connects itself with a Telnet client (way to send commands to my lights), and I’d like to read signals from my process to know, for example, the name of the light I should turn on. 
I’ve written a JavaDelegate in order to listen to events names :
public class ProcessListener implements JavaDelegate { public String signalName; @Override public void execute(DelegateExecution execution) throws Exception { try { signalName = execution.getEventName().toString(); } catch (Exception e) { e.printStackTrace(); } } }
My issue is to call this class on my Java Server class. I don’t know what to put as an argument calling “this.listen.execute” even if I know it shoulb be a DelegateExecution type… I guess I need some implementation examples. Here’s my Server :
package opec.opec_server;
import java.io.InputStream;
import java.io.PrintStream;
import opec.opec_server.ProcessListener;import org.apache.commons.net.telnet.TelnetClient;
public class Server implements Runnable {
int telnetPort = 23;
String lutronIP = “192.168.0.101”;
String userName = “USER”;
String password = “Lutron”;
String mem = “”;
TelnetClient tc;
InputStream in;
PrintStream out;
ProcessListener listen;public Server() {
//init ProcessListener
this.listen = new ProcessListener();//connection to the Telnet client this.tc = new TelnetClient(); try { this.tc.connect(this.lutronIP); System.out.println("Connexion Successfull."); } catch (Exception e) { e.printStackTrace(); }}
// Some …
//Functions…
//Later…
public void run() {//this.listen.execute(); How do I call that ?? if(this.listen.signalName != this.mem) { switch(this.listen.signalName) { case "TurnOnIMB": this.out.println("#OUTPUT,11,1,30"); this.out.flush(); case "TurnOnZI": this.out.println("#OUTPUT,10,1,30"); this.out.flush(); case "TurnOffAll": this.out.println("#OUTPUT,10,0,0"); this.out.flush(); this.out.println("#OUTPUT,11,0,0"); this.out.flush(); default: ; } mem = this.listen.signalName; }}
public static void main(String args) {
int n = 0;
Server mySrv = new Server();
mySrv.authentification();
while(n != 1000) {
mySrv.run();
n++;
}
mySrv.disconnect();
}
}
Thank you in advance for your time and consideration,
Emma.
