implementation I must point out:

-For sessions being tied to a specific context (one mapped to a URI) a Cookie

If you are not sure you want to keep the object around then you may set
it at the page or session level instead of application.

Yes to the above but note unloading a servlet does not mean the

Assuming JSP .92 you could do something like:

You cannot use forward after calling getOutputStream or getWriter. So
check your code to see where either getOutputStream or getWriter is
being called.
Gabri
The move is towards to use of forward/include because its a more direct
method than sendRedirect. sendRedirect has to open a URL connection to
the forward address then return the result to the browser.
RequestDistpatcher however is a direct call on the Server Engine

then we have a problem. If I have a shared Object with the method foo,
I the developer must make sure simulataneous calls to foo is feasible
and does not cause conflict - e.g foo may be calling a member variable
that is not synchronized.

You can access request info primarily by 2 methods:
1)
2)
<%
String servername = request.getServerName();
ause Cookies
are sent as part of the Http Headers and so it won't work if there is a
out.println call before the addCookie method call.
Hope this helps...

it allows for the PROGRAMMATIC separation of business logic and

For SSI handling in JSP, is the SSI Include inserted into the JSP before

Yep the use of "bean" was quite confusing to me at first. Main thing to
remember is that the object follow the set/get access naming ...

Steve,
The solution you give is for the following situation:
Object[] obj = mybean.getObject();
for (i = 0; i < obj.length;i++)
Object[] obj2 = obj[i];
The original question is how to deal with multidimensionals:
Object[][] obj = mybean.getObject();

Some clarifications on the following would be appreciated:
