Presentation Transcript

    1. Java Server Pages - Programming Can have Java code between the tags <% // and %>

    2. Java Server Pages - Programming <html<title>JSP code</title><body> <% int sum = 0; for( int i = 0; i < 10; i++) sum += i; out.print( "the sum is " + sum ); %> </body></html>

    3. JSP – using classes <html<title>JSP code</title><body> <% java.util.Date d1 = new java.util.Date( ); out.print( d1 ); %> </body></html>

    4. JSP – Using classes Instead of using the full path for a class java.util.Date We can import the class with a page directive <%@ page import = "java.util.Date" %> There can be any number of page directives within a JSP page

    5. JSP – Directives JSP directives are enclosed between <%@ and %> The 2 primary directives are Page directive ? used primarily for import statements Include directive ? used for including files

    6. JSP – Using classes <html<title>JSP code</title><body> <%@ page import = "java.util.Date" %> <% Date d1 = new Date( ); out.print( d1 ); %> </body></html>

    7. JSP – Using classes We can import more than one class Use a comma separated list of classes that you want to import <%@ page import = "java.util.Date, java.util.StringTokenizer" %>

    8. JSP – Using classes <html<title>JSP code</title><body> <%@ page import = "java.util.Date, java.util.StringTokenizer" %> <% Date d1 = new Date( ); out.print( d1 + "<br><br>"); StringTokenizer st = new StringTokenizer( "apple pear nut kiwi" ); int num = st.countTokens( ); out.print( "There are " + num + " tokens” ); %> </body></html>

    9. JSP – Using classes We can use several page directives to import classes <%@ page import = "java.util.Date" %> <%@ page import = "java.util.StringTokenizer " %>

    10. JSP – Using classes We can use a bulk import statement in a page directive to import all the classes needed from a given package <%@ page import = "java.util.*" %>
