Send a message only to one user

[magsam]

Hello,

I need more comfort for my chatusers. In my application I use chat and notify. I works fine. The users want a sign when somebody wants to chat with them, like in skype. The minimized chatdialog is in the taskbar.

The best sign would be a growl message. The PushContext is deprecated (pushContext.push(channels.getChannel(privateUser), new FacesMessage("Hello I want to chat with you",summary)); ) .

With : eventBus.publish(CHANNEL ,
new FacesMessage(StringEscapeUtils.escapeHtml(summary),
StringEscapeUtils.escapeHtml(privateMessage)));

I reach all subscribers and not the only one to whom I want to chat.

Does anyone know a solution?

Thanks and regards from

Peter

Create a specific channel per user. See the primefaces chat example where private 1 to 1 chatting is also possible

Hello kukeltje,

I tried your solution without success. In the chat is we use no "new FacesMessage" . My "normal" chat works fine, I have no problems with it.

Well, I took the chat example as a starting point and with some little modifications it did work.... So unless you post code, it is difficult to say where your problem is

Hello Kukeltje,
here is my code for better understanding:

Code: Select all

@ManagedBean
@ViewScoped
public class ChatView {	

	@ManagedProperty("#{logon}")
	private Logon logon;
	private Usr usr;

	private final EventBus eventBus = EventBusFactory.getDefault().eventBus();
			 
	@ManagedProperty("de.osretail.basis.ChatUsers")
	private ChatUsers users = new ChatUsers();
 
	private String privateMessage;
	 
	private List<Usr> listeuser = null;
	private String username = null;
 
	private String user;
	private int listid;	
	private int first;
	private boolean loggedIn;
	private String privateUser;
 
 	private final static String CHANNEL = "/{room}/";
 	private final static String CHANNELA = "/{anfrage}";

	private String summary, detail;
	private boolean neu = false;
	
	public void nullsetzen() {		
		 first=0;			 	
	}

	public void sendPrivate() {		
		if(first==0){
			first=1;
			summary = "Guten Tag " +privateUser;	
			// only the selected user should get the message
	 	eventBus.publish(CHANNELA , 
	   				new FacesMessage(StringEscapeUtils.escapeHtml(summary),
	   						StringEscapeUtils.escapeHtml(privateMessage)));	
	 	
		eventBus.publish(CHANNEL + username, privateUser +": "
	  			+ StringEscapeUtils.escapeHtml(privateMessage));
		}else{	
			
  		eventBus.publish(CHANNEL + privateUser, username +  ": "
 				+ StringEscapeUtils.escapeHtml(privateMessage));
			 		
  	eventBus.publish(CHANNEL + username, username + ": "
  			+ StringEscapeUtils.escapeHtml(privateMessage));
		privateMessage = "";	
		}	
	}

	public void login() {
		RequestContext context = RequestContext.getCurrentInstance();
		users.add(username);
		context.execute("PF('subscriber').connect('/" + username + "')");
		RequestContext.getCurrentInstance().update("form:users");		  
		loggedIn = true;
	}

	public void disconnect() {
		loggedIn = false;
		username = null;
	}

	public void ini() {
		usr = logon.getUsr();
		user = usr.getBenutzer();
		username = usr.getUsername();
		username = username.replaceAll(" ", "_");
		username = username.replace("Ä", "Ae").replace("Ö", "Oe").replace("Ü", "Ue").replace("ä", "ae").replace("ö", "oe").replace("ü", "ue").replace("ß", "ss");	
		neu = true;
	}

	public boolean isNeu() {
		if (username == null) {
			ini();			
		}
		return neu;
	}	  

and the resource

Code: Select all

 @PushEndpoint("/{anfrage}")
@Singleton
public class AnfrageResource {		    
    @OnMessage(encoders = {JSONEncoder.class})
    public FacesMessage onMessage(FacesMessage message) {    	 
        return message;
    }     
}  
 

The growl is in the header of the template.

Code: Select all

<div xmlns:h="http://xmlns.jcp.org/jsf/html"
	xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
	xmlns:f="http://xmlns.jcp.org/jsf/core"
	xmlns:p="http://primefaces.org/ui" class="header">

	<p:socket onMessage="handleMessageA" channel="/{notify}" />
	<p:socket onMessage="handleMessageA" channel="/{anfrage}" />

	<script>
		function handleMessageA(facesmessage) {
			facesmessage.severity = 'info';
			PF('growl').show([ facesmessage ]);
		}
	</script>

	<h:form id="formheader">
		<p:growl widgetVar="growl" showDetail="true" life="10000"
			escape="false" />

You can test it. Call : http://osretail.de:8082/osRetail/ . You need a secound users it's max .. Klick in the toolbar of the first dialogue after the logon on chat and in the popup login. . Choose the user max and send a first message. You see the message. Of course all users receive the message

Thank you and regards

I do not fully understand what you describe here, but what I think you mean is that even if you select a specific user to send a private message, everybody receives it, but I cannot realy try to reproduce in osretail (nice extensive app btw, I mentioned that earlier, but hirering a ui designer might help )

One thing that I noticed is that I miss the endpoint for {room}/...
