Thanks very much Mark!
I'm reasonably happy about safeguarding concurrent access in a
threaded environment, but the last time I did anything like that in
Java was before 1.5, so I don't know the java.util.concurrency
package; I'll look into it, particularly the Concurrent* classes.
Thanks.
However this all seems to emphasise an area in which my understanding
is lacking. A lot of the stuff I've read about java.util.concurrent -
and the description of that book - talk a fair amount about thread
concurrency.
Are you saying that I need to implement what I'm talking about using
threads, even within Mina? I thought the point of frameworks like Mina
was to avoid scaling with threads. Am I missing something?
Thanks,
Igor

Hi there,
I'm thinking about using Mina for an application which will give
clients
read/write access to a single data structure containing a map of
objects
which change over time. The clients will need to be able to say
"give me
list of objects at location X", "put object X at location Y", etc.
The very basic idea is to have a singleton map object with which
clients
communicate. Obviously the data this object managed needs not to be
corrupted, deadlocked or stuck in race conditions. In a threaded
version,
I'd start to think about synchronization, but I'm not sure of the
correct
approach using Mina.
Does anybody have any pointers, or Is there some documentation as
to how
to manage the concurrent access to this structure within Mina? Or
perhaps
suggestions for better ways to do it in this context?
Many thanks,
Igor
