    1. 1. Chapter 2JSP Element http://www.java2all.com
    2. 2. JSP Element http://www.java2all.com
    3. 3. In previous example described in introduction to JSP, We didn`t use any java statement or code in the file. If the developer wants to put any java code in that file then the developer can put it by the use of jsp tags(elements). There are mainly three group of jsp tags(elements) available in java server page :1 ) JSP Scripting elements2 ) JSP Directive elements3 ) JSP Standard Action elements All three elements described in next three topic. http://www.java2all.com
    4. 4. JSP Scripting elements http://www.java2all.com
    5. 5. 1. JSP Scripting elements : There are four types of tag in jsp scriptingelements.a) JSP Declaration tag.b) JSP scriptlet tag.c) JSP Expression tag.d) Comment tag.Now we describe each tag in detail. http://www.java2all.com
    6. 6. a) JSP Declaration tag : A JSP declaration lets you declare or define variables and methods (fields) that use into the jsp page. Declaration tag Start with <%! And End with %> The Code placed inside this tag must end with a semicolon (;).Syntax: <%! Java Code; %> http://www.java2all.com
    7. 7. <%! private int i = 10; %> <%! private int squre(int i) { i=i*i; return i; }%> You can also put these codes in a single syntaxblock of declaration like, <%! private int i = 10; private int squre(int i) { i=i*i; return i; }%> Note : The XML authors can use an alternativesyntax for JSP declaration tag: http://www.java2all.com
    8. 8. <jsp:declaration> Java code;</jsp:declaration>EX.<jsp:declaration> private int i = 1; </jsp:declaration> <jsp:declaration> { private int squre(int i) i=i*i; return i; }</jsp:declaration> You can also put these codes in a single syntax block ofdeclaration like,<jsp:declaration> private int i = 1; private int squre(int i) { i=i*i; return i; }</jsp:declaration> http://www.java2all.com
    9. 9. Remember that XML elements, unlike HTMLones, are case sensitive. So be sure to use lowercase. Declarations do not generate any output so thedeveloper uses declaration tag with JSP expression tagor JSP scriptlet tag for generating an appropriateoutput for display it in the appropriate browser. http://www.java2all.com
    10. 10. b) JSP scriptlet tag : A JSP scriptlet lets you declare or define anyjava code that use into the jsp page. scriptlet tag Start with <% and End with%> The Code placed inside this tag must endwith a semicolon (;). Syntax: <% Java Code; %> http://www.java2all.com
    11. 11. EX.<% int a = 10; out.print("a ="+a);%>Note : The XML authors can use an alternativesyntax for JSP scriptlet tag.<jsp:scriptlet> Java code;</jsp:scriptlet> http://www.java2all.com
    12. 12. c) JSP Expression tag : A JSP expression is used to insert Java values directlyinto the output. JSP Expression tag is use for evaluating any expressionand directly displays the output in appropriate web browser. Expression tag Start with <%= and End with %> The Code placed inside this tag not end with asemicolon (;). Syntax: <%= Java Code %> http://www.java2all.com
    13. 13. For example. the following shows the date/timethat the page was requested: Current time: <%= new java.util.Date() %> Note : The XML authors can use an alternativesyntax for JSP expressions:<jsp:expression> Java Expression</jsp:expression> http://www.java2all.com
    14. 14. d) Comment tag : Although you can always include HTMLcomments in JSP pages, users can view these if theyview the pages source. If you dont want users to beable to see your comments, embed them within the <%-- ... --%> tag. <html> <head> <title>Comment demo</title> </head> <body> <p>This is simple demo of test the comment </p> <!-- This is a comment. Comments are not displayed in the browser but displayed in view source --><%-- This is a comment. Comments are not displayed in the browser as well as not displayed in viewsource also --%> </body></html> http://www.java2all.com
    15. 15. Output : This is simple demo of test the comment. Now right click on the browser and select theview source so we can get the code in Notepad like,<html> <head> <title>Comment demo page</title> </head> <body> <p>This is simple demo of test the comment. </p> <!-- This is a comment. Comments are not displayed in the browser but displayed in view source --> </body></html> In the view sorce code, the comment put in <%--comment --%> will not display but the comment putin <!—comment will display. http://www.java2all.com
    16. 16. Now using these JSP Scripting elements, we are developing somesimple examples so the use of these tags can easily understood.<html> <head> <title>Scripting Demo page</title> </head> <body> <%-- declaration tag --%> <%! int i = 10; %> <%-- scriptlet tag --%> <% out.print("i = "+i); %> <br> <br> <% out.print("for loop execution start..........."); %> <br> <% for(int j=1;j<=10;j++) { out.print("j = "+j); %> <br> <% } http://www.java2all.com
    17. 17. out.print("for loop execution complete..........."); %> <br> <br> <%-- expression tag --%> <%! int a = 10; int b = 20; %> The addition of two variable : a + b = 10 + 20 = <%= a+b %> <br> <br> Current time : <%= new java.util.Date() %> </body></html http://www.java2all.com
    18. 18. Output : i = 10for loop execution start...........j=1j=2j=3j=4j=5j=6j=7j=8j=9j = 10for loop execution complete........... The addition of two variable : a + b = 10 + 20 = 30 Current time : Sun Feb 12 14:00:35 IST 2012 http://www.java2all.com
    19. 19. JSP Directive elements http://www.java2all.com
    20. 20. 2. JSP Directive elements : A JSP directive gives special information aboutthe page to JSP Engine. Each JSP goes through two phases:(1) The first phase is known as translation time,during which the JSP engine turns the file intoa servlet. (The step following from 1 to 5 in JSPArchitecture) http://www.java2all.com
    21. 21. • The second phase is known as request time, during which the resulting servlet is run to actually generate the page. (The step following from 6 to 9 in JSP Architecture) The JSP engine handles the directives at translation time because the JSP engine will translate a particular directive into a servlet only for the first time so the developer can get more speed for the process of loading a JSP file in a future.Syntax: <%@ directive-name [attribute=”value” attribute=”value”………….] %> http://www.java2all.com
    22. 22. Note : The XML syntax for defining directivesis<jsp:directive.directiveType [attribute=”value”attribute=”value”………….] /> Three main types ofdirectives are:a) page directiveb) include directivec) taglib directive http://www.java2all.com
    23. 23. a) page directive : The page directive is used to specify attributes for the JSP page as a whole. The page directive does not produce any visible output when the page is requested but change the way the JSP Engine processes the page. e.g., you can make session data unavailable to a page by setting a session to FALSE. http://www.java2all.com
    24. 24. Syntax: <@ page [attribute=”value”attribute=”value”………….] %> The table given below describes the possibleattributes for the page directive. http://www.java2all.com
    25. 25. SyntaxAttribute Description (default value is Example in bold) This tells the server about the language to be used <%@ pagelanguage in the JSP file. Presently language="java" language="java" the only valid value for %> this attribute is java. This attribute defines the import="packag <%@ page Import list of packages, each e.class" import="java.util. separated by comma . *, java.io.*"%> Indicates the superclass <%@ page extends="packaExtends of servlet when jsp extends="com.Co ge.class" translated in servlet. nnect"%> http://www.java2all.com
    26. 26. true indicates session should be bound to the existing session if one exists, otherwise a new session="true| <%@ page Session session should be created false" session="true"%> and bound to it and false indicates that no sessions will be used. specifies the buffer size buffer="sizekb| <%@ page Buffer for out and default is 8kb. none" buffer="8kb"%> True indicates multithreading and false <%@ page isThreadSafe="trisThreadSafe indicates that the servlet isThreadSafe="tr ue|false" should implement ue"%> SingleThreadModel http://www.java2all.com
    27. 27. true indicates that the buffer should be flushed when it is full and false autoflush="tru <%@ page autoFlush indicates indicates that e|false" autoFlush="true"%> an exception should be thrown when the buffer overflows. <%@ page This defines a string that info="This is a simple info="message Info can be retrieved via the jsp file created by " getServletInfo method. Java2all team on 22 Feb 2011"%> <%@ pagepageEncodin This defines data type of pageEncoding= pageEncoding="ISO- g page encoding. "ISO-8859-1" 8859-1"%>contentType This specifies the MIME contentType=" <%@ page type of the output. MIME-Type" contentType="text/h tml; charset=ISO-8859-1" http://www.java2all.com
    28. 28. <%@ page This defines isELIgnored="isELIgnored isELIgnored="false ENUM data type. true|false " "%> This indicates whether or not <%@ page isErrorPage="trueisErrorPage the current page isErrorPage="false |false" can act as the "%> error page. Define a URL to another JSP that is invoked if an <%@ pageerrorPage unchecked errorPage="url" errorPage="error.j runtime sp"%> exception is thrown. http://www.java2all.com
    29. 29. <%@ page language="java" import="java.util.*,java.io.*" extends="com.Connect" autoFlush="true" errorPage="error.jsp" info="This is a simple jsp file created by Java2all team on 22 Feb 2011" isELIgnored="false" isErrorPage="false" session="true" buffer="8kb" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" isThreadSafe="true"%>NOTE : The XML equivalent of<%@ page import="java.util.*" %> is<jsp:directive.page import="java.util.*" /> http://www.java2all.com
    30. 30. b) include directive : It allows a JSP developer to include source code(static resource) of a file inside jsp file at thespecified place at a translation time. Typically include files are used for headers,footers, tables and navigation that are common tomultiple pages. The included page should not be anotherdynamic page so the included file does not need to bea complete and valid JSP or servlet. http://www.java2all.com
    31. 31. Syntax:<%@ include file="/folder_name/file_name"%> If the included file and JSP file are available inthe same folder then the folder name is not required insyntax. <%@ include file="file_name"%> Now we are describe the include directive byone simple example so the use of include directive inJSP file is easily understand. http://www.java2all.com
    32. 32. Step-1 : Create two folder in webRoot (i) HTMLFILE and (ii) JSPFILE.Step-2 : Create a new HTML file(Included.html) in HTMLFILE folder.Step-3 : Replace the source code of a file(Included.html) by the below code.<html> <head> <title> Included.html </title> </head> <body> <b>This is HTML page which is include in JSP file by using directive include tag in JSP file.</b> <br> </body></html> http://www.java2all.com
    33. 33. Step-4 : Create a jsp file(IncludeDemo.jsp) in JSPFILE folder.Step-5 : Now replace the source code of a file(IncludeDemo.jsp) by the below code.<%@ page language="java" import="java.util.*,java.io.*" pageEncoding="ISO-8859-1"%><html> <head> <title> IncludeDemo.jsp </title> </head> <body> This is a JSP page. <br><%@ include file="/HTMLFILE/“Included.html"%> </body></html> http://www.java2all.com
    34. 34. Step-6 : Now Redeploy the Project and start the Server.Step-7 : Enter the appropriate URL in web- browser. http://www.java2all.com
    35. 35. Output : This is a JSP page. This is HTML page which is include in jsp file by using directive include tag in jsp file. http://www.java2all.com
    36. 36. c) taglib directive : The taglib directive makes custom actionsavailable in current page through the use of taglibrary.Syntax:<%@ taglib uri="tag Library_path"prefix="tag_prefix"%>uri ====> The absolute path (URL) of a Tag LibraryDescriptor.prefix ====> A unique prefix used to identify customtags from library used later in the JSP page. http://www.java2all.com
    37. 37. EX.<%@ taglib uri="/tlds/TableGenerator.tld"prefix="tg"%> And if TableGenerator.tld defines a tag namedtable, then the JSP file can contain tag of followingtype:<tg:table>……….……….</tg:table>NOTE : We discuss taglib directory in detail infurther chapter. http://www.java2all.com
    38. 38. JSP Standard Action elements http://www.java2all.com
    39. 39. JSP Standard Action elements: Actions are high-level JSP elements that create,modify or use other objects. Unlike directives and scripting elements, JSP arecoded using strict XML syntax form. By the use of JSP actions elements you candynamically insert a file, reuse JavaBeanscomponents, forward the user to another page, orgenerate HTML for the Java plugin etc. http://www.java2all.com
    40. 40. The standard action types are:(1) <jsp:param>(2) <jsp:include>(3) <jsp:forward>(4) <jsp:fallback>(5) <jsp:plugin>(6) <jsp:useBean>(7) <jsp:setProperty>(8) <jsp:getProperty> http://www.java2all.com
    41. 41. (1) <jsp:param> The <jsp:param> action is used to provide othertags with additional information in the form of namevalue pairs. This action is used in conjunction withjsp:include, jsp:forward and jsp:plugin actions.Syntax :<jsp:param name=”parameter_name”value=”parameter_value” /> http://www.java2all.com
    42. 42. OR <jsp:param name=”parameter_name” value=”parameter_value”> </ jsp:param> For Example,<jsp:param name=”font_size” value=”20” />OR<jsp:param name=”font_size” value=”20”> </jsp:param > http://www.java2all.com
    43. 43. (2) <jsp:include> This action allows a static or dynamic resourceto be including in the JSP at request time. If page is buffered then the buffer is flushedprior to the inclusion.Syntax :<jsp:include page= “file_name” flush = “true|false”/> http://www.java2all.com
    44. 44. OR<jsp:include page= “file_name” flush = “true|false” ><jsp:param name=”parameter_name” value=”parameter_value” /></jsp:include >NOTE : A <jsp:include> action may have one or more <jsp:param> tags in its body, to provide additional name-value pairs. http://www.java2all.com
    45. 45. Included.jsp :-<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Included.jsp</title> </head> <body> This is the message of Included.jsp file..............<br> </body></html>Include.jsp :-<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Include.jsp</title> </head> <body> This is the message of Include.jsp file..............<br> <jsp:include page="Included.jsp" /> </body></html> http://www.java2all.com
    46. 46. Now run the Included.jsp in the appropriate browser so you can get the below output in the browser,Output: This is the message of Include.jsp file.............. This is the message of Included.jsp file..............Example-2 : Write a simple program which demonstrate the use of <jsp:param> in <jsp:include> action element. http://www.java2all.com
    47. 47. Employee.jsp :-<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Employee.jsp</title> </head> <body> <b><i><% out.print("Name : "+request.getParameter("name1")); %></i></b> <br> <% out.print("He is a "+request.getParameter("profile1")+" dept. in Noble Engineering College - Junagadh."); %> <br> <b><i><% out.print("Name : "+request.getParameter("name2"));%></i></b><br> <% out.print("He is a "+request.getParameter("profile2")+" dept. in Noble Engineering College - Junagadh."); %> </body></html> http://www.java2all.com
    48. 48. Information.jsp :-<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Information.jsp</title> </head> <body> <jsp:include page="Employee.jsp"> <jsp:param value="Prof. Ashutosh A. Abhangi" name="name1"/> <jsp:param value="H.O.D. of Info. Tech. " name="profile1"/> <jsp:param value="Prof. Kamal N. Kotecha" name="name2"/> <jsp:param value="H.O.D. of C.S.E. " name="profile2"/> </jsp:include> </body></html> http://www.java2all.com
    49. 49. Now run the Information.jsp in the appropriate browser so you can get the below output in the browser,Output: Name : Prof. Ashutosh A. Abhangi He is a H.O.D. of Info. Tech. dept. in Noble Engineering College - Junagadh. Name : Prof. Kamal N. Kotecha He is a H.O.D. of C.S.E. dept. in Noble Engineering College - Junagadh. http://www.java2all.com
    50. 50. NOTE : Difference between Directive includeand Action include element. IncludedInclude Syntax Done when Parsing Content <%@include file=”file_na CompilationDirective Static Container me”%> time <jsp:include Request Not parsed Static or Action page=”file_n Processing but included dynamic ame”%> time in container http://www.java2all.com
    51. 51. (3) <jsp:forward> With the forward action, the current page stops processing the request and forwards the request to another page. Execution never returns to the calling (current) page.Syntax :<jsp:forward page= “file_name” />OR<jsp: forward page= “file_name”><jsp:param name=”parameter_name” value=”parameter_value” /></jsp: forward> http://www.java2all.com
    52. 52. The meaning as well as use of the attributes and the <jsp:param> element are same as for <jsp:Include> action element.Example-1 : Write a simple program which demonstrate the <jsp:forward> action element.Current.jsp :<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Current.jsp</title> </head> <body> This is a Current page <jsp:forward page="Forward.jsp" /> </body></html> http://www.java2all.com
    53. 53. Forward.jsp :<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Forward.jsp</title> </head> <body> Welcome, Forward is working now and this is a Forwarded page...............<br/> </body></html> Now run the Current.jsp in the appropriate browser so you can get the below output in the browser,Output: Welcome, Forward is working now and this is a Forwarded page............... http://www.java2all.com
    54. 54. Example-2 : Write a simple Login Application by using <jsp:forward> action element.Login.jsp :<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Login.jsp</title> </head> <body> <form action="Check.jsp"> User Name : <input type="text" name="name"> <br> Password : <input type="text" name="password"> <br> <input type="submit" value="Sign in"> <input type="reset" value="Reset"> </form> </body></html> http://www.java2all.com
    55. 55. Check.jsp :<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Check.jsp</title> </head> <body> <% String name = request.getParameter("name"); String password = request.getParameter("password"); if(name.equals("Ashutosh") && password.equals("java")) { %> <jsp:forward page="Success.jsp"></jsp:forward> <% } else { %> <jsp:forward page="Retry.jsp"></jsp:forward> <% } %> </body></html> http://www.java2all.com
    56. 56. Retry.jsp :<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Retry.jsp</title> </head> <body> Wrong User ID and Password, Please try again by click below link…………<br> <b><i><a href="Login.jsp"> Login page </a></i></b> </body></html>Success.jsp :<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><html> <head> <title>Success.jsp</title> </head> <body> <h1>You are successfully login................. </h1> </body></html> http://www.java2all.com
    57. 57. Now run the Login.jsp in the appropriatebrowser so you can get the below output, http://www.java2all.com
    58. 58. Now put the, User Name : aaaaaa Password : jjjjjj And click on Sign in button so you can get the below output in browser,Output : Wrong User ID and Password, Please try again by click below link…………………….. Login page By clicking the Login page link, the Login.jsp page is call and you can put the http://www.java2all.com
    59. 59. User Name : AshutoshPassword : java And click on Sign in button so you can get the below output in browser,Output : You are successfully login................. http://www.java2all.com
    60. 60. (4) <jsp:fallback> Syntax : <jsp:fallback> text message for user </jsp:fallback> A text message to display for the user if the plug-in cannot be started. If the plug-in starts but the applet or Bean does not, the plug-in usually displays a popup window explaining the error to the user. Its use with <jsp:plugin> element. http://www.java2all.com
    61. 61. (5) <jsp:plugin> By the use of <jsp:plugin> you can include an applet and JavaBean in your JSP page. Syntax of <jsp:plugin> is : http://www.java2all.com
    62. 62. Syntax :<jsp:plugin type="bean|applet“ code="className.class“ codebase="Path of className.class after moving it in WebRoot“ [ name="name of bean or applet instance" ] [ align="bottom|top|middle|left|right" ] [ height="displayPixels" ] [ width="displayPixels" ] [ jreversion=" version of Java Runtime environment " ] ................. > http://www.java2all.com
    63. 63. [<jsp:params> <jsp:param name="parameter_name" value="parameter_value" /> .......... </jsp:params>] [<jsp:fallback> text messag.......... </jsp:fallback>] </jsp:plugin> http://www.java2all.com
    64. 64. Example-1 : Write a simple application in which the applet is used in JSP file by <jsp:plugin> action element.• Create a Applet_Jsp.java file(applet) in default package at src in your Web Project(JSP_EXAMPLE). The source code of this java file(applet) are as under, http://www.java2all.com
    65. 65. Applet_Jsp.java :import java.applet.Applet;import java.awt.Button;import java.awt.Color;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;public class Applet_Jsp extends Applet implements ActionListener{ public void init() { setBackground(Color.black); Button r = new Button("RED"); add(r); r.addActionListener(this); Button g = new Button("GREEN"); add(g); g.addActionListener(this); Button b = new Button("BLUE"); add(b); b.addActionListener(this); } http://www.java2all.com
    66. 66. public void actionPerformed(ActionEvent e) { if(e.getActionCommand().equals("RED")) setBackground(Color.red); if(e.getActionCommand().equals("BLUE")) setBackground(Color.blue); if(e.getActionCommand().equals("GREEN")) setBackground(Color.green); }}(2) Now, Run this applet.(3) Create one new folder, name is AppletClass in WebRoot.(3) Now,Copy the Applet_Jsp.class file(compile file/Bytecode file) which is available at…………… workspace.metadata.me_tcatwebappsYour_Project_na meWEB-INFclasses Applet_Jsp.class in AppletClass folder in WebRoot. http://www.java2all.com
    67. 67. (4) Create a Applet_Use_In_Jsp.jsp file in JSPFILES folder at your Web Project(JSP_EXAMPLE). The source code of this jsp file are as under,Applet_Use_In_Jsp.jsp :<%@ page language="java" %><html><head><title>Applet_Use_In_Jsp.jsp</title></head><body><jsp:plugin type="applet" code="Applet_Jsp.class" codebase=" http://localhost:8080/JSP_EXAMPLE/AppletClass" width="500" height="500"> <jsp:fallback> <p>Unable to load Applet..............</p> </jsp:fallback></jsp:plugin></body></html> http://www.java2all.com
    68. 68. • <jsp:useBean> Forms are a very common method of interactions in web sites.The standard way of handling forms in JSP is to define a "bean". For that you just need to define a class that has a field corresponding to each field in the form. The class contains the "setters" and “getter” method of the form fields. By this action element <jsp:useBean>, we use java bean in a JSP page. http://www.java2all.com
    69. 69. Syntax : <jsp:useBean id="bean id" class="beans class" scope="page|request|session| application" />Scope of <jsp:useBean> :1. page: This is default value. It means that we can use the Bean within the JSP page. It indicates that the bean is only available on the current page (stored in the PageContext of the current page).2. request: It means that we can use the Bean from any JSP page processing the same request. http://www.java2all.com
    70. 70. A value of request indicates that the bean is only available for the current client request (stored in the ServletRequest object).3. session: It means that we use the Bean from any Jsp page in the same session as the JSP page that created the Bean. A value of session indicates that the object is available to all pages during the life of the current HttpSession.4. application: It means that we use the Bean from any page in the same application as the Jsp page that created the Bean. http://www.java2all.com
    71. 71. A value of application indicates that it isavailable to all pages that share the sameServletContext.(7) <jsp:setProperty> This action sets the value of a bean’s property.Syntax : <jsp:setProperty name="beans id"property="property Name”value="property value"/> http://www.java2all.com
    72. 72. (8) <jsp:getProperty> This element retrieves the value of a beanproperty, converts it to a string, and inserts it into theoutput.Syntax : <jsp:getProperty name="beans id" property="property name"/>Example : Write a simple program whichdemonstrate the <jsp:useBean>,<jsp:getProperty>and <jsp:setProperty> action elements. http://www.java2all.com
    73. 73. Student_Data.java :package bean;public class Student_Data{ private String name = null; private String email = null; private int age = 0; public String getName() { return name; } public String getEmail() { return email; } public int getAge() { return age; } http://www.java2all.com
