12. Student Record Application Run Cycle   Install or Start StudentRecord Application   Call up JSP   Stop StudentRecord application

13. Install or Start StudentRecord Application

14. Contextlistener start an Application public void contextInitialized(ServletContextEvent sce) { ServletContext sc= sce.getServletContext(); ServletContext sc= sce.getServletContext(); try try { StudentPackage.StudentDB studentdb= new StudentPackage.StudentDB(); StudentPackage.StudentDB studentdb= new StudentPackage.StudentDB(); sc.setAttribute ("studentdb", studentdb); sc.setAttribute ("studentdb", studentdb); } catch (Exception e) catch (Exception e) { sc.log ("Couldn't create database attribute: " + e.getMessage ()); sc.log ("Couldn't create database attribute: " + e.getMessage ()); } }// end of public void contextInitialized(ServletContextEvent e) }// end of public void contextInitialized(ServletContextEvent e)

15. Call up Home.jsp

16. Use StudentDB instance <% StudentPackage.StudentDB studentdb= (StudentPackage.StudentDB) application.getAttribute("studentdb"); StudentPackage.StudentDB studentdb= (StudentPackage.StudentDB) application.getAttribute("studentdb"); Collection students = studentdb.getStudents(); Collection students = studentdb.getStudents();%>Home.jsp

17. Stop Student Record Application

18. Contextlistener stop an Application public void contextDestroyed(ServletContextEvent sce) { ServletContext sc = sce.getServletContext (); ServletContext sc = sce.getServletContext (); StudentPackage.StudentDB studentdb = (StudentPackage.StudentDB) sc.getAttribute("studentdb"); StudentPackage.StudentDB studentdb = (StudentPackage.StudentDB) sc.getAttribute("studentdb"); studentdb.close(); studentdb.close(); sc.removeAttribute ("studentdb"); sc.removeAttribute ("studentdb"); }

19. Prepare Database Create table Create table CREATE TABLE STUDENTDB ( ID NUMBER(10) NOT NULL PRIMARY KEY, FIRSTNAME VARCHAR2(30) NOT NULL, FIRSTNAME VARCHAR2(30) NOT NULL, SURNAME VARCHAR2(30) NOT NULL SURNAME VARCHAR2(30) NOT NULL); Insert student record Insert student record insert into studentdb (id, firstname, surname) values (101,'Emma','Dean');

20. Configure Application StudentRecord's Development Directory under NetBeans

21. Configure Application (Cont.) build.properties build.properties

22. Configure Application (Cont.) Build.xml Build.xml Server.xml Server.xml Web.xml Web.xml

23. Configure Application (Cont.) /src/*.java /src/*.java

24. Configure Application (Cont.) /web/*.jsp /web/*.jsp

25. Building, Installing, Deploying Use ANT to build, install and deploy Student Record Application Use ANT to build, install and deploy Student Record Application Use Neatbeans IDE to build Student Record Application Use Neatbeans IDE to build Student Record Application

26. Run Application

27. End Thank you.
