    probleam in granularity of interception

    Fábio Costa Newbie

      I am needing to intercept the call of a constructor in my application.
      When the instantiation occurs within of a method called for the system executes correctly. However, the instantiation occurs, in fact, inside of a constructor of another object. This another object is singleton. In this case the pointcut is not running. What it can be?

      
      Running:
      
      public class ServletInit extends HttpServlet {
      
       public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
       EmployeeRecord er = new EmployeeRecord(null);
       ...
       }
      }

       ...

            I have no clue on what is going on with your example.
            Could you please send me your jboss-aop.xml file, and tell me the weaving mode you are using (aopc compiler, loadtime weaving or hotswap)?

              When the method HealthWatcherFacade.getInstance() is called the attribute modified in the constructor of EmployeeRecord is intercepted(I used keyword ?all? to discover this interception):

              this.employeeRepository = rep;

                  Which version of JBoss AOP are you using?

                    Fábio Costa Newbie

                    JBoss Application Server: 4.05 GA
                    JBoss AOP:1.5.2

                    The standalone mode run correctly. I make tests using a class with the method main. The problem only occurs when the system is in application server.

                      I changed the way of packaging, with loadtime weaving activated, without success. The instantiations are not intercepted if they occur of indirect way.
                      I already tried to use keywords execution, call and construction.

                      What it can be happening?

                        I changed file jboss-aop.xml. The shown error is abnormal because the class is present in jar of the WEB-INF/lib directory.

                          I've just run an example and it works to me, no matter whether the servlet calls directly the constructor, or the private constructor of HealthWatcherFacade does it.

                          Please, run your servlet only with the pontcut:

                           <pointcut name="recordsCreation"
                           expr="call(employee.EmployeeRecord->new(..))" />
                          



                          and the binding:
                          
                          
                           <bind pointcut="recordsCreation">
                           <advice
                           aspect="aspects.dataManagement.nonpersistent.DataCollectionNonPersistent"
                           name="aroundRecordsCreation" />
                           </bind>
                          
                          


                          And tell me if you can see on the aopc log something like:

                           [aopc] [debug] was HealthWatcherFacade converted: true
                          


                          This line will appear either way. The only thing is that JBoss AOP should instrument it. If it doesn't, this line will appear with a false instead of true.

                                The empoloyee shouldn't be converted.
                                You are intercepting the call, and the call to the constructor is inside HealthWatcherFacade.

                                So, this is step is ok.

                                Next test (this may seem a silly question, but we need to check everything): are you sure doPost is being called?
                                Use a System.out.println to verify that. And, is the constructor of HealthWatcherFacede being called too?
                                And, finally, put a print inside of the constructor of EmployeeRecord.

                                Something is wrong here, and we need to find out which step is messing your example.
