This slide covers a basic overview of jsp(java server pages) including various types of tags used in jsp for different purpose.

1. Learning JSP Java server pages

3. Read the implicit request data sent by browser.

4. Generate the result

5. Send the explicit data to client

7. A JSP page is a text based document containing static HTML and dynamic actions which describe how to process a response to the client in a more powerful and flexible manner

8. Can be used to code presentation logic

9. Can be used to generate dynamic pages

11. Bits of HTML embedded in Java code

12. Suitable for coding the business layer of an enterprise application

13. Created and maintained by Java programmers

14. JSP

15. Bits of Java code embedded in HTML

16. Suitable for coding the presentation layer of an enterprise application

19. Jsp in various scenarios

21. request - HttpServletRequest

22. response- HttpServletResponse

23. session - HttpSession

24. application - ServletContext

25. config - ServletConfig

26. exception - Throwable / JspException

27. pageContext- PageContext

29. Scripting elements

30. Directive elements

31. Action elements

32. Template data– Any thing other than the above mentioned four categories fall under template data This will include all HTML tags and text

35. <%= request.getRequestURI() %>

36. <%= request.getProtocol() %>

37. <%= request.getQueryString() %>

38. <%= request.getContentLength() %>

39. <%= request.getContentType() %>

40. <%= request.getServerName() %>

41. <%= request.getServerPort() %>Example:ReadRequestInfo.jsp

44. This can be used to include contents of some other file in a jsp. Ex:<%@ include file = "../Header.html" %>

46. Beans:jsp:useBean jsp:setProperty jsp:getProperty

48. public getter and setter methods. “get” and “set” followed by same word. property name is derived by changing first character to lowercase.

49. Setter argument type and getter return type must be identical

51. Minimizing Java code in a JSP will enable even a web designer to maintain it.

53. Class

54. Scope 1.)Page 2.)Request 3.)Session 4.)Application

56. Appears inside the body of a jsp:useBean element, which is executed only if a new object was instantiated, not if an existing one was found.

57. The associated attributes are:name property param value

61. The two required attributes are name of a bean, and property whose value should be inserted.

62. Ex:<jsp:getProperty name ="myWishBean" property = "wish" />Example:Employee.jsp

63. Benefits of jsp JSP is a technology for coding the presentation logic of an enterprise application Web designers without programming skills can create and maintain JSP Use JSP technology without having to learn the Java language: You can use JSP technology without learning how to write Java scriplets JSP is more convenient, not more powerful. You can use standard Web-site development tools. For example,we use Macromedia Dreamweaver for most of the JSP pages in the book.
