    @Stateless
    public class MyStatelessBeanA {
        @Resource
        private SessionContext sessionCtx;  

       public byte[] methodA(){
          MyStatelessBeanA myStatelessProxy1 = this.sessionCtx.getBusinessObject(MyStatelessBeanA.class);
          MyStatelessBeanA myStatelessProxy2 = this.sessionCtx.getBusinessObject(MyStatelessBeanA.class);

          Future<byte[]> proxy1Future = myStatelessProxy1.asynchMethod();
          Future<byte[]> proxy2Future = myStatelessProxy2.asynchMethod();

          byte[] firstArray = proxy1Future.get();
          byte[] secondArray = proxy2Future.get();

          return ...

       }

       @Asynchronous
       public Future<byte[]> asynchMethod(){
           byte[] byteArray = ...
           ...do something including select from various table...
           return new AsynchResult<byte[]>(byteArray);
       }

基本上我想做的是asynchMethod()从两个代理对象并行调用两次。

问题？
