Craig,
I did try this way but it still does not work. Since supplier.value is of type
SupplierBean, do I have to specify that anywhere?
------------------------------------------------------
<jsp:useBean id="user" scope="session" type="com.motorola.mms.msqc.beans.UserBean"/>
<TABLE>
<logic:iterate id="supplier" name="user" property="suppliers" >
<TR>
<TD><bean:write name="supplier" property="value.seq_nbr" scope="page"/></TD>
<TD><bean:write name="supplier" property="value.name" scope="page"/></TD>
<TD><bean:write name="supplier" property="value.countryName" scope="page"/></TD>
</TR>
</logic:iterate>
</TABLE>
-----------------------------------------------------
but this code which I am trying to replace with tags works:
<jsp:useBean id="user" scope="session" type="com.motorola.mms.msqc.beans.UserBean"/>
<TABLE>
<%
Hashtable hashTable = (Hashtable) user.getSuppliers();
for (Enumeration e = hashTable.elements(); e.hasMoreElements(); )
{
SupplierBean supplier = (SupplierBean) e.nextElement();
%>
<TR>
<TD><FONT face = "Arial">supplier.getCode() %></FONT></TD>
<TD><FONT face = "Arial"><%= supplier.getName() %></FONT></TD></FONT></TD>
<TD><FONT face = "Arial"><%= supplier.getCountryName() %></FONT></TD>
</TR>
<% } %>
</TABLE>

When you iterate over a Hashtable (or any other implementation of the Map interface),
the object get for the "id" variable is actually an implementation of
the "Map.Entry" class, not the class of the value of the bean. From this "Map.Entry"
instance, however, you can easily get to the real information:
<bean:write name="supplier" property="value.seq_nbr" scope="page"/>
This works because a MapEntry has two properties -- key and value -- so we are using
the nested property syntax to effectively call getValue().getSeq_nbr().
