Send message to client before session invalidated

i am using jsp and java servlet tech. for my web application.
my problem is :
i want to send a message to client before session invalidated.
please help me to find the best way to solve my problem.

You can detect session termination by putting an object in the session attributes which implements HttpSessionBindingListener. What you can't do is send a message to a client, basically because all http transactions are initiated by the client. The only way I can see you could do this is to put an applet on your web pages which periodically consults the server concerning the session state.
Then the problem is that there's no obvious way of determining if the session is about to timeout, only whether it has or not. Your applet couldn't return the session cookie (as such) because that would reset the session timeout and the session would never expire. If you could obtain the session without reseting the expiry (perhaps from SessionContext though that's depracated) you could look at getLastAccessedTime() and getMaxInactiveInterval, but I don't know that this can be done. You can't even count, on some systems, on the session remaining in memory.
If you really need to do this you may need to consider implementing sessions for yourself. I've done this for non-webapp based logins and it's not too hard.

Sending messages between clients

hi,
I want to make small instant messenger,like yahoo.I have made a server which accept connection from different client & send online user list to each and every client connected to the server.
But now i have to send messages between the clients(chatting).
This can be do either through server or allow server establishing connection betwwen two client & allow them to continue chatting session.But i am not able to figure out how i do either of the things using socket programming.
Please help me ,to establish chatting session between the clients.
Thank you for replies

Yes, It should be Non public to Other client but not to server.
Suppose client1 want to send message to client2 then it send message to server,then server passes this message to client2.
Now as client2 got the it send some reply to client1 which
is also reach to client1 through server.But I have problem ,as how
does client2 knows to which client he has send message as no of clients are connected to the server & more then one client has send message to client2.
Basically I have problem in sending reply to a message send by the different client connected to the server.
Thank You for reply

Send message from client problem

Hi all,
i want send some JMS messages from standalone client program to MDB through OC4J JMS service. I wrote little sample client program:
     public static void main(String [] args)
          throws Exception
          Hashtable env = new Hashtable();
          env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
          env.put(Context.SECURITY_PRINCIPAL, "admin");
          env.put(Context.SECURITY_CREDENTIALS, "admin");
          env.put(Context.PROVIDER_URL, "ormi://localhost:23791/");
          Context context = new InitialContext(env);
          QueueConnectionFactory connectionFactory = (QueueConnectionFactory)context.lookup("jms/my/test.queueConnectionFactory");
          QueueConnection connection = connectionFactory.createQueueConnection();
          QueueSession qSession = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
          Queue q = (Queue)context.lookup("jms/my/test.queue");
          QueueSender sender = qSession.createSender(q);
          connection.start();
          TextMessage message = qSession.createTextMessage();
          message.setText("Text messaga no.: "+i);
          sender.send(message);
          sender.close();
          qSession.close();
          connection.close();

Hi radovan,
Check your jdk versions at your server and client. Make sure that your are running your server and client with the same jre. Even i had the same problem when oc4j was started with jdk1.4 jre and running the client using jdk1.3.
Hope this helps

How to send message to Client about Server shutdown.

I have made a Chatting Application using RMI.
I need to send messages to all the Clients when a Server shutdowns abnormally.
One way is that I use shutdown hook on the Server Application.
But, what if the power of the machine on which server is running goes off. How will the Client get to know that server is down.
I also want that If a Client shutdowns abnormally,it should send the message to the Server which in turn will send message to other Clients about the particular Client.
Thanks & Regards.
Nimesh

Before you make any call form client to server check that sever is available. This is easily done by intorudciing an rmi method that will return true e.g m_sever.isAvalable(); if server is availbel you will get ture if not then you will get an RMI Excpetion which you then trap and attemp to reconnect to the server (NAming.lookup() ) .. if several attempts fail then assume server is down.
When a client dies it throws an excpetion on the sErver :
java.net.SocketException: Connection reset by peer: JVM_recv in socket input stream read

How to send message to client?

Hello, I'm newbie in J2EE. I have a client (e.g. GUI class) which have to "connect" to EJB and start further processing when others 3 clients also connect to this EJB. It's not a problem to obtain reference to EJB and connect to it, but I don't know how to send some message from EJB to client.
I've tried to implement it with events, but it not works. Is it possible to use event for this? Are there any patterns to solve this class of problems? Please, help!
Below fragments of my code for events:
GamesListFrame.java
      try
         title.setText("text");
         tablesManager = getHome().create();
         tablesManager.addStartGameListener(this);
         tablesManager.generateEvent();
      } catch ...
}and TablesManagerBean.java
    * @ejb.interface-method
    *     view-type="remote"
   public void generateEvent()
      EventQueue q = Toolkit.getDefaultToolkit().getSystemEventQueue();
      StartGameEvent event = new StartGameEvent(this);
      q.postEvent(event);
    * @ejb.interface-method
    *     view-type="remote"
   public void addStartGameListener(StartGameListener listener)
      listenerList.add(StartGameListener.class, listener);
   public void processEvent(AWTEvent event)
      if (event instanceof StartGameEvent)
         EventListener[] listeners = listenerList.getListeners(StartGameListener.class);
         for (int i=0; i<listeners.length; i++)
            ((StartGameListener)listeners).GameStarted((StartGameEvent)event);
else
super.processEvent(event);

How to send message from Message Driven Bean to JMS client?

In my project I have JMS client, two QueueConnectionFactory and Message Driven Bean. Client send message to MDB through the first QueueConnectionFactory , in one's turn MDB send message to client through the second Queue Connection Factory . I already config my Sun AppServer for sending message in one way, and sending message from MDB to the second QueueConnectionFactory. But on my Client there is an error : �JNDI lookup failed: javax.naming.NameNotFoundException: No object bound to name java:comp/env/jms/MyQueue2� (jms/MyQueue2 � this is the name of my Queue). So it couldn't get this message.
P.S.
Thank you for help!!!

What is the name of the second queue?is the connection factory on the local?Yes the connection factory is on the local. The name of my first queue is jms/MYQueue and the name of another one is jms/MyQueue2.

Send XML to client: message box

Hi,
In a BPM workflow I'm putting together, I need to open a message box for information
(title, message, OK button). In the documentation, I found that I should send
an XML document to a client that looks like this:
<message-box title="title" style="information" options="ok">
<actionid>"1013679664318"</actionid>
</message-box>
Which I did: I added a "Send XML to client" action in the "True" part of a decision
node with a message-box element and its attributes, and actionid as a nested element.
When I trigger the workflow, it goes through all the expected steps but the window
does not pop up at all. I could not find the reason why anywhere. So has anyone
experienced the same problem ? If yes, how did you solve it ?
Cheers,
Yann

Hi Sudhar.
I don't think your workflow will execute the next node before you mark the current
node as done. Conseqently setting the done in the decision box isn't possible.

Send message from java not client

I have a java app running on my server and I'd like to send

My simple chat server does not send messages to connected clients

Hi!
I´m developing a chat server. But I can not get it work. My client seems to make a connection to it, but my server does not send the welcome message it is supposed to send when a client connects. Why not?
removedEdited by: Roxxor on Nov 24, 2008 10:36 AM

Ok, I solved my previous problem and now I have got a new really annoying one.
This is a broadcasting server which meand it can handle multiple clients and when one client sends a message to the server, the server should broadcast the message to all connected clients. It almost works, except that the server just sends the message back to the last connected client. The last connected client seems to steal the PrintStream() from the other clients. How can I solve that?

Yes this could be the reason, because at the time of Receiver Determination it tries to send the message to both the interface. Are both the scenario Proxy to XI??
Try to change the Message Interface in IR and accordingly change in ID also and then try.

Any ideas? Thanks very much,

Hi,
Proxies communicate with the XI server by means of native SOAP calls over HTTP .RFC does not, so you have to convert from SOAP to RFC calls and vice versa. So XML conversion is required.
ABAP Proxies uses Webservice and Http Protocols. And if you use RFC it is mainly meant for Sync. call. But Proxies is used for both Sync and Async.
If you use ABAP Proxy , you can reduce the overhead calling the function again and again.

Re: JDBC Sender select/update problem
If u generate proxy for outbound interface then its client proxy and for inbound interface its server proxy.
In client proxy u can call the method to send messages but u can't modify it but in server proxy its possible to write a user code within the method to execute proxy.
CLIENT PROXY:
A WSDL description from a UDDI server (or an Internet page) is usually used to make a service executable in the Internet and to describe the interface of this service. You require a client proxy and not a server proxy to call this service by using the Web service infrastructure.
SERVER PROXY:
You can only generate ABAP server proxies from a WSDL description if they originate in the Integration Repository.You can also generate server proxies for Java and client proxies for ABAP from message interfaces.
