    ok I got the server to send something. Problem indeed was with the client. Here's proof that he is transmitting:

    But I still get only loading. Looks like client is not interpreting correctly.

    Here is NEW client:
    <html>

    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"></meta>
    <script language="JavaScript" src="LS/lscommons.js"></script>
    <script language="JavaScript" src="LS/lspushpage.js"></script>
    </head>

    <body>
    <h1>Simplest</h1>

    <div id="F|table1|stream|Next|div" class="">loading...</div>


    <script>




    var page = new PushPage();
    page.onEngineCreation = function(engine) {
    engine.connection.setAdapterName("SIMPLEST");
    engine.changeStatus("STREAMING");
    }
    page.bind();
    page.createEngine("SimplestApp", "LS", "SHARE_SESSION");

    var pushtable = new OverwriteTable(stream, null, "DISTINCT");
    page.addTable(pushtable, "table1");



    </script>
    </body>

    </html>
    And now I get error that there are no elements in table table1

    the server is sending only probes, no data at all. Debug step by step your adapter and check that it is sending the data to its listener.


    About the client you've two errors now:

    you should not change your html to be like this:

    leave it as it was before


    and you still have the undefined variable stream in your table constructor:

    change it as I've shown you on my first post.

    looks like subscription method isn't even called!! I've put a breakpoint on every single line of the subscription method. Nothing. I get that trace when I activate page in browser but looks like it doesn't subscribe...

    did you fix the client page? Paste here a server log.

    A subscribe on the data adapter for a certain item is called only when a client subscribes to that item. If the client is broken so that it does not subscribes to your item (as in the previous server log) the subscribe on the data adapter is never called

    I did it. Had a smaaaaaaall but very significiant error. My file reader was not reading well. And subscribe name was different. Now it works and sends data.

    Well then, now I have another question. I have to make a graph from data I recieve. It must be in realtime. Can I have your recommendation? Maybe store the recieved data in a buffer or something so I can access it and plot a graph? Mentor suggested I use adobe flex for plotting.

    Hi,
    you can follow three paths:
    1. Plot a graph with html using our ChartTable (doc), custom code or a third party library
    2. Pass your data through our FlashBridge (doc) to a flash application and create your graph there
    3. Use our Actionscript client (doc) to receive pushed data directly on your flex application.
