Hi friends,
I am using java applet that will perform some operations. Now it is independent of jsp or html page. So,if i close an applet my html page remains active and Vice-Versa. What i want to do is embed an java Applet in html page itself. When i click on LOGIN BUTTON on login.htm page. That should invoke one method called PopUpAtt() which is in another jsp page(applet.jsp). In order to implement it,what i am doing is I just created one more jsp page called applet.jsp that contains my applet invoking code as like follows,(I have Given this code inside body tag) and I tried with one more way by using onload in body tag(<body onload="PopUpAtt()">).
But,Am getting ClassNotFoundException.. I need your help.. Please help me..
This is my applet.jsp page.
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import="java.io.*,java.util.*"%>

And one more issue also.. i am working with spring application only.So,if i didnt write any controller for this jsp page,it is return me with page not found exception. If i write controller,then it will take me to the applet.jsp page,where i can see the preview of Applet with classnotfoundexception. can i invoke my applet without spring framework ah? I think,I can.. Because by simply clicking on LOGIN Button.it will invoke my applet. So,if i give give like as follows in login.htm page.
<script>
$("#appletinvoke").click(function()
{
$('#appletinvoke').load('<%= request.getContextPath() %>/jsp/applet.jsp');
});
</script>
<input type="button" class="buttons" id="appletinvoke" value="Sign" />
Is it correct?
Please help me..

did you check the source code at that link?
just re-read the first part of your original post..
an applet written IN a jsp file? that makes .... no sense to me at all. the problem might be that you haven't created a correct applet.

No. What i wrote is that I have jsp page that contains code to invoke applet,not of applet creation..
Ya.. I just red your link and tried my applet is not working with jnlp file.. any other way to implement applet embedding friends..
