[jboss-user] [Beginner's Corner] - Re: Number of stateless beans

piotrekde [http://community.jboss.org/people/piotrekde] created the discussion "Re: Number of stateless beans" To view the discussion, visit: http://community.jboss.org/message/582853#582853 -------------------------------------------------------------- I found that I can use org.jboss.ejb3.common.proxy.plugins.async.AsyncUtils in the following way: @Stateful public class ComputerBean implements ComputerRemote {       @EJB     private ProcessorLocal processor;       public void startComputations() {         Random r = new Random();         while(true) {             AsyncUtils.mixinAsync(processor).compute(r.nextInt());         }     } } Then it is possible to use Future interface to get result (when it will be ready). I tested it - works, but I have also noticed something strange. Let's consider following code: @Stateless public class ProcessorBean implements ProcessorLocal {       private static int COUNTER = 0;       @PostConstruct     public void init() {         System.out.println("constructing");         COUNTER++;     }       @PreDestroy     public void destroy() {         System.out.println("destroying");         COUNTER--;     }       public void compute(int i) {         System.out.println("----------------> " + COUNTER);           // some dummy computations - it's here only in order to take some time         double d = 0.3;         for (int j=0; j<100; j++) {             d+= 0.2 % 4 + i;         }     } } Counter is increased and printed to the console - it looks as SLSB are pooled and their number is increased when needed. However, counter is _never_ decremented - even if I stop computations for 15 minutes and then restart it. I would say that I expected that after some downtime number of pooled SLSB will go to some small number. Is this something wrong with my code (some hold references etc.) ?
