This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
in my scea assignment for Part-2, there is a requirement to call 3 different web services on every minute. I am planning to use javax.ejb.TimerService api for EJB3 for this purpose.My ideas is that during the application startup there will be a servlet invocation(say the name of the servlet is StartUpController) which in turn will call an SLSB(say TimerSessionBean) and that bean will have a method like createTimer() and another method like handleTimeout() with @timeout annotation.
Call sequence will be :
public void handleTimeout(Timer timer) will contain 3 different web service calls.
StartUpController class will have <load-on-startup>1</load-on-startup> in web.xml so that it gets invoked on application startup.
StartUpController can be used for many other purposes like caching, logger initialization etc.
I will put the details stated above in the short note below my class diagram.
In my class diagram I am showing FacesServlet by the name BaseController with <<Servlet>> stereotype. In addition to BaseController, I am planning to show StartUpController with the same <<Servlet>> stereotype and TimerSessionBean with <<StatelessSessionBean>>.
Is my decision to include StartUpController and TimerSessionBean in the class diagrams correct or am I giving too much details not intended for the class diagram in scea? I am bit confused. Please help me by giving your opinion regarding this.
