BTW, you CAN access files, but this also may harm multi-host scalability
There's however ways of doing this, for example, a jdbc-file driver (a jdbc
driver that fires upon a filesystem instead
of a database); I think there's one freely available from an O'Reilly book
on servlets (i used to have it while I worked
in Argentina, but lost it when moved to Chile)
However, have in mind that accessing to the LOCAL filesystems (and not a
single fs) will affect your app's scalability
I've had this problem and had to solve it by building a distributed service
that replicates and synchronizes dirs (sorry guys, can't release it). That's
the primary reason fs didn't make the spec; the lack of a good jdbc-fs
driver is the other.

why many clients? is that a 'performance enhancement'? (orion's got a pool
of objects, so no perf enhancements to do)
do you wish to model a singleton?
please, elaborate further.

PS: shoooting from the hip.... a stateless session bean with its fields set
up as
public static MyFieldType myfield;
won't do? (altough obviously a multi VM solution totally craps this pattern)

I don't want to do any database activity. I just want this Java Object to be
accessible as an EJB accessible by many different clients hosted by an
Application Server. The object doesn't have to be stateful either.
