Question 3: Using a standard J2EE application develop and deploy EJB Web Service to find the difference between two values. The EJB web service should include three main components: the Web service container, the java Sevlet that works as a broaker, and the web form that works as a front- end for the end user to invoke data. The following tasks shall be considered to develop the scenarios. [6 Marks] A. Create new project of Java EE application named "Mathful and inside I create a java session bean "mathup" with the package name "goodMath". This bean contains the web service function named "diffComp that determines and returns the difference between two parameter variables. B. Create a suitable HTML web form in the "index.html" for the end-user to parse the required values to the parameters at server WS's function diffComp. C. Create a java servlet named "calcThis" with a package named "clepkg that works as a client middleware between the form and the session bean service and integrate it properly with the scenario (by linking it to client's HTML form and the WS function diffComp). D. Deploy and demonstrate the EJB service.
