Hi Aaron,
Vector of vectors will help you. Each row is a vector. Put this vector in
another vector. put this vector in session. get that vector in jsp and
traverse into the vector and display the whole table.
For example,
followinf code goes IN servlet
import java.util.*; // for vector
Vector table = new Vector();
for (int i = 0; i < number of rows;i++){
Vector row = new Vector(4);
row.addElement(Item);
row.addelement(Description);
row.addElement(Price);
row.addElement(Quantity);
table.addElement(row);
}
session.putValue("Table",table);
in JSP
Vector table = (Vector)session.getValue("Table");
while (table.hasMoreElements()){
Vector row = (Vector)table.NextElement();
String item = row.ElementAt(0);
String description = row.ElementAt(1);
String price = row.ElementAt(2);
String quantity = row.ElementAt(3);
// display
<td><item></td>
<td> description</td>
<td> price </td>
<td> quantity</td>
}
Good luck.
Aparna

Subject: Storing sessions
Hello all. I am trying to figure out how to store a group of parameters in
session so that I can store multiple groups and print this out into an html
table. What I can't figure out is how to store a group of parameters in the
session object. My group of parameters consists of this: Item, Description,
Price, Quantity, and Total. Now I need to store those five parameters with
difference values for each item that I have. So my html table would look
something like this.
Item Description Price Quantity
Total
8923 some description $80.29 4
$321.16
2983 second product desc $20.50 2
$41.00
I have been thinking about holding this information in an object and then
holding the object in session, but I can't figure out how to a uniqe object
for each product. I also realize that a database would be the best way to do
this, but I can't use a database for this, so session seemed to be the next
best thing.
Also, is there anyway to create multiple uniqe sessions? I seem to remember
that there is a way to do this using ASP/VBScript, but I can't seem to do
this same thing in Java.
thanks,
Aaron
