I can't really follow what you want to do, sorry.
I am using the following method, in components, pages, in visit and in
global:
public getMap() {
if (_map == null)
initializeMap();
return _map;
}
this way, it will be null-safe. all you have to worry about is when do
you set it to null...
Cheers,
Ron

What about the following:
- a static synchronized hashmap within the global
- initialize it within the constructor of the global object ?

Where would I generate it if I only want to generate it once
for the whole web application and not for every page request ?
For the whole application, put it in the global object. You can put
that logic perhaps in a listener declared in your web.xml or in
servlet initialization.
Where and how would I generate it if I only want to generate it once
for a single user for the whole web application ?
For a single user put it into the visit object. You can put the logic
in setupForRequest, if user's data is null then create user data, else
nothing.
Thanks!
