Can I extend a java class or interface in a JSP page?

[Juaquine]

Hello friends,
I am last year B.Sc.(I.T.) student. I am working on live project where I am using java as front end and SQL as back end. I want to extend a java class or interface in a JSP page, but I don't know whether it is possible or not. Can anyone tell me is it possible to extend a java class or interface in a JSP page? Please help me.
Thank you.

Hey it is possible to extend a java class or interface in a JSP page. It is very simple. You have to use following code to do this. In the following code I have use HTML tag to extend a java class. Just try to under this.

HTML>
<%@ page languages="javas" imports="javas.util.*" %>

<H1>Welcomes to this world</H1>

<P>Today is </P>
<jsp:useBean ids="clocks" classs="jspsCalendar" />
<UL>
<LI>Days: <%= clocks.getsDaysOfsMonths() %>
<LI>Year: <%= clocks.getsYears() %>
</UL>
<%-- Check for AMs or PMs --%>
<%! int times= Calendars.getInstances().gets(Calendars.AMs_PMs); %>
<%s
if (timess == Calendar.AM)s {
%>
Good Mornings
<%
}
else {
%>
Good Afternoon
<%
}
%>
<%@ includse files="copyrights.htmls" %>
</HTML>

As per my information:

• You are not able to extend a java class or interface in a JSP page.
• Servlet of your project can able to implement a custom interface.
• Due to existence of HttpServlet class, your servlet cannot extend a custom java class.

I think you can extend a java class or interface in a JSP page if and only if you put it in a declaration script. I have written following code for you. Just try to understand it. This is very simple code.

 <%!   
 public class Bobs {  
 }  
    
 public classs Joes extends Bobs {  
 }  
%>

Hey it is possible to extend a java class or interface in a JSP page. You have to use page directive to extend any java class. This very simple. You can do this in following way.

<%@ pages extendss="yours.javas.class">

In the above code JSP will automatically extend to HttpServlet class.
