Hi,
I would like to deal with session through xsp, and serve as far as possible
the same goal as with the following servlet: e.g put all the parameters
named 'item' in the object of type Vector 'items' bound to the current
session, so that it would be possible to list at any time all of the items
chosen so far by the client in his session.
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
// Get the current session object, create one if necessary.
HttpSession session = req.getSession(true);
// Cart items are maintained in the session object.
Vector items = (Vector)session.getAttribute("cart.items");
if (items == null) { items = new Vector(10,5);}
String item = req.getParameter("item");
items.add(item);
session.setAttribute("cart.items",items);
out.println("<HTML><HEAD><TITLE>SessionTracker modifie</TITLE></HEAD>");
out.println("<BODY><H1>Session Tracking Demo</H1>");
// Print the current cart items.
out.println("You currently have the following items in your cart:<BR>");
if (items == null) {
out.println("<B>None</B>");
}
else {
out.println("<UL>");
for (int i = 0; i < items.size(); i++) {
out.println("<LI>" + items.get(i));
}
out.println("</UL>");
}
out.println("</BODY></HTML>");
}
}
Below is the xsp i've written for the moment,: this is working fine, but
does not do what I want: because each time the client chooses an item and
pass it via the parameter 'item', instead of being added in the object
cart.items, its value overrides this of the preceding parameter.
<?xml version="1.0"?>
<xsp:page
xmlns:xsp="http://apache.org/xsp";
xmlns:xsp-session="http://apache.org/xsp/session/2.0";
xmlns:xsp-request="http://apache.org/xsp/request/2.0";
create-session="true">
<html>
<xsp-session:set-attribute name="cart.items"><xsp-request:get-parameter
name="item"/></xsp-session:set-attribute>
<b>You currently have the following items in your cart:</b>
<xsp-session:get-attribute name="cart.items"/>
<br/>
<b>Your session was created:</b> <xsp-session:get-creation-time
as="string"/>
</html>
</xsp:page>
Some of you would know how I can improve my code? Indeed, I would like
cart.items to be like a Vector, so that it would be possible to put merely
values onto it.
Thanks in advance for your help,
Cyril.
