Hi,
I am learning
JSP and i have Apache
tomcat 4.1 on my machine. i had been able to compile and run
servlets successfuly. i get this error while practising DIRECTIVES.
code for JSP:
<%@ page extends="usingjsp.jspSuperclass" %>
<html>
<body>
i a asubclass extending the superclass
this is a msg form my superclass : <br>
<%= request.getAttribute("demo") %>
</body>
</html>
code for servlet:
package usingjsp;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
public abstract class jspSuperclass extends HttpServlet implements HttpJspPage
{
public final void init(ServletConfig config) throws ServletException
{
super.init(config);
jspInit();
}
public final void destroy()
{
super.destroy();
jspDestroy();
}
public final ServletConfig getServletConfig()
{
return super.getServletConfig();
}
/*public final void service(HttpServletRequest request, HttpServletResponse response)
throws ServletException,java.io.IOException
{
super.service(request,response);
} */
public final void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, java.io.IOException
{
super.service(req,res);
req.setAttribute("demo","Hi from the superclass");
_jspService(req,res);
}
public void jspInit()
{
}
public void jspDestroy()
{
}
public abstract void _jspService(HttpServletRequest req, HttpServletResponse resp)
throws ServletException,java.io.IOException ;
}
the location of jsp is: apache group\tomcat 4.1\root\nfiles\pagdir.jsp
location for servlet is: apache group\tomcat 4.1\root\nfiles\jspSuperclass.java
the compiled file jspSuperclass.class is present in both the nfiles\usingjsp folder as well as root\webapps\web-inf\classes folder.
