Subject Simple But Irritating problem accesing beans from jsp
Date Fri, 24 Sep 2004 06:26:59 GMT
the following code is working perfectly:

<%@page import="com.dinesh.*" %>
<% IdCard myidcard=new IdCard();%>
<%
myidcard.setName("HariKiran");
myidcard.setRollNo("123");
%>
<%=myidcard.getName()%>
<br>
<%=myidcard.getRollNo()%>

but if i replace it with jsp:usebean tag  like this :

<%@page import="com.dinesh.*" %>
<jsp:usebean id="myidcard"  class="com.dinesh.IdCard" scope="page">
<jsp:setProperty name="myidcard" property="rollNo" value="123" >
<jsp:setProperty name="myidcard" property="name" value="Harikiran" >
<%=myidcard.getName()%>
<br>
<%=myidcard.getRollNo()%>
</jsp:usebean>

i am getting a jsp.error.badaction messsage here is complete stack trace :
