    org.jboss.cache.lock.TimeoutException on using transaction

    stelang stelang Newbie

      Hi,
      I am running 2 servlets using weblogic on the same m/c i.e. on 2 jvms. I am using the configuration file from the example http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheAndWebLogic
      with the only change being : org.jboss.cache.GenericTransactionManagerLookup
      The 1st servlet on getting the cache reference does the foll:
      while(true)
      {
      tx.begin();
      cache.put("root/resources", "count", "1");
      System.out.println("in txn :" + cache.get("root/resources"));
      Thread.sleep(15000);
      tx.commit();
      }

      The 2nd servlet has:
      while(true)
      {
      cache.put("root/resources", "count", "2");
      }

      On starting the 2 instances of weblogic server, I run the 1st servlet and when it starts the transaction, I run the 2nd servlet. I see this exception on running the 2nd servlet:

      Is this a known issue? Is there any workaround for this issue? I see this only on using transaction. If I remove the transaction boundaries set in 1st servlet, everything works fine.Thanks in advance. Appreciate your help.
