RE: How do I iterate thru a hashtable using iterate tag?

[Shamdasani Nimmi-ANS004]

If the objects I am storing in my hashtable are of a bean type how would I access the 
properties of the bean in iterate? e.g., if the bean has get methods for properties 
Code, name, countryName, etc. I want to display these thru iterate tag on my JSP.

Craig answered a similar question on Sunday.  I think it might help you,
there he stated:

    When you iterate over a Hashtable (or any other Map), the elements of 
    the iteration are of class "Map.Entry", which has two properties --
    "key" and "value".

The other posting did not appear to need a Hashtable and he further
suggested the possible use of an ArrayList, etc.  If that would work in your
situation it might simplify your problem.

Hi,

Could someone please tell me what I am doing wrong below:

user is a bean in session scope in my JSP and its getSuppliers() method
returns a hashtable where keys are Suppliers Ids and elements are Supplier
beans. 


<logic:iterate collection="<%= user.getSuppliers() %>" id="supplier"
type="com.motorola.mms.msqc.beans.SupplierBean">

<TR>
<TD><bean:write name="supplier" property="seq_nbr" scope="page" /></TD>
<TD><bean:write name="supplier" property="name" scope="page" /></TD>
<TD><bean:write name="supplier" property="country_name" scope="page" /></TD>
</TR>

</logic:iterate>

------------------------------------------------------
I had the following code earlier and that was working.

<%
        Hashtable hashTable = (Hashtable) user.getSuppliers();
        for (Enumeration e = hashTable.elements(); e.hasMoreElements(); ) {
        SupplierBean supplier = (SupplierBean) e.nextElement();
%>

<TR>

<TD><%= supplier.getCode() %></FONT></TD>
<TD><%= supplier.getName() %></TD>
<TD><%= supplier.getCountryName() %></FONT></TD>
</TR>

<% } %>

Thanks in advance.
