Hi Guys,
I have been getting this strange error where I get a bean not found
error when I use <logic:iterate> . The issue
is that if I substitute the <logic:itearate> with a plain <% scriptlet
%> the JSP does not complain i.e It is able
the ArrayList in the session.
Can someone help ??
Here is my code
FacultyAction.java
-----------------------------
....
....
....
st.setId(rset.getString(1));
st.setName(rset.getString(2));
st.setSubject(rset.getString(3));
st.setQualification(rset.getString(4));
al.add(st);
}
if( count == 0 )
return mapping.findForward("failure");
HttpSession session = request.getSession(true); //
Create a new session
session.setAttribute("results", al);
.....
struts-config-faculty.xml

I have tried putting scope = "session" here but I get the same
problem.

</logic:iterate>

Instead of the logic block if I put this stuff below , It works just
fine.
<%
ArrayList al = (ArrayList)session.getAttribute("result");
if(al != null)
{
%>
<tr>
<td>ID</td>
<td>Name</td>
<td>Subject</td>
<td>Qualification</td>
</tr>
<%
for(int i=0; i < al.size(); i++)
{
bean.Faculty st = (bean.Faculty)al.get(i);
%>
<tr>
<td><%= st.getId() %></td>
<td><%= st.getName() %></td>
<td><%= st.getSubject() %></td>
<td><%= st.getQualification() %></td>
</tr>
<%
}
}
%>
Please help. I have tried everything within my little knowledge.
Thanks
