    DistributrdMap

    theone Newbie

      Hi,
      I am trying to get 'hold' of 'DistributedMap', stroe some application level data into it and make it available across the cluster.(Jboss-3.0.8)

      1. Facing problem in looking up the service. I got a code written by Scott from google, and tried to run a part of it. Its a simple lookup.
      (The server is running in clustered mode)

      InitialContext ctx = new InitialContext();
      String jndiName = "/HAPartition/" + "DefaultPartition";
      ------->HAPartition partition = (HAPartition) ctx.lookup(jndiName);
      DistributedMap entryMap = partition.getDistributedMapService();

      How ever i get a classcast exception at the --------> line

      Do i have to do domething extra to get this running
      2. I f i get hold of DistributedMap, where I can find methods to retrieve/put objects into it.

      3. Is DistributedMap gonna take care of repllication of changed values across the cluster.

      Excuse me for an array of quesitons, but i am not able to get good resource on this.

      regards,

      theone.

            hi theone,

            sacha is not on holliday, he is busy with sales in EU and most of the staff is in training/support. So we answer the free forums whenever we can.

            If you really need to grab our attention for a serious problem in prod or development the best way is to get a support contract with us.

            I don't mean to sound salesy but we do what we can to help for free, working on our schedules. Working on your schedule == dollars

              Eh... its been a while since I worked on 3.0.x, so I am not sure if this is applicable:

              It would be simpler to just make a JMX call to the DistributedState MBean and call the set(String category, String name, Serializable serializable).

                Hey Nick thanks a lot.

                Marc, that was a friendly nudge to Sacha. I know that it is dificult to get a share of time from YUR schedule(Which probabaly you dont have much )....but that is what i can rely upon as the other option of "Dollars" is not feasible with me (Coz i dont have that much :-)......
