RE: java.lang.ClassCastException
Hi,
I have a JSP page in which I intend to generate text boxes at run time. I
have written a CreateHandler class which actually returns a Collection of
Collection of Collection of Form bean objects for the input box. This way I intend to map the text boxes to
their corresponding Form beans. However when I try using this page I donot
get the text boxes on the page. It goes blank. I found out that a
java.lang.ClassCastException occurs from the Tomcat log file. Please suggest
what could be the possible cause.
The following is the JSP code:
<%@ page import="java.util.*"%>
<%@ page
import="com.untd.sss.struts.*" %>
<%jsp:useBean id="ch"
class="com.struts.CreateHandler"/>
<%
Collection v2,v3,v4;
Collection v =
(Collection)ch.getCollectionbean();
for(Iterator i =
v.iterator();i.hasNext();)
{
v2 =(Collection)i.next();
for(Iterator i2 =
v2.iterator();i2.hasNext();)
{
v3 =(Collection)i2.next();
for(Iterator i3 =
v3.iterator();i3.hasNext();)
{
v4 =(Collection)i3.next();
%>
<%
}
}
}
%>
The exception:
java.lang.ClassCastException: com.untd.sss.struts.CreateForm

RE: Struts custom tags tutorial
Hi Steve, Let me clarify: I know some of the basic concepts of struts and I have been using things like the Action class, the Form class etc. But the point is, after having finished the work on the backend logic, I have to present my data in the form of tables on the page. Now the table dimensions, the colours used, etc. can vary based on the data generated. So I wanted to use custom Struts tags on the page where the table has to be generated and displayed. Then I want to put my code corresponding to these struts tags else where. This way the logic to display the data will not be there on the JSP page. This is my problem. I have tried to get the right tutorial for this but my search has noy yielded the right results. Can you please help me.

RE: How to add Java Script to a JSP page with struts tags
Hi Rohit,
I am getting the message: "error on page" followed by a "done" on the left
hand corner of the explorer. After this control simply gets forwarded to the
page that I have set as "forward"(in struts-config.xml) value on "failure".
That is, the java script seems to be ignored by the browser.
