Replication question 2004-01-12 - By John Sidney-Woollett

Hi
For replication purposes (2 or more tcs in a cluster), how do you let the
sessionlistener know to re-replicate your session after you make a change
to a property of an object which is bound to the session, but where the
session attribute + object iself remains unchanged?
For example, if I bind a (lightweight and serializable) class to the
session and change one of its properties, how do I notify Tomcat that I
want the session replicated again. Probably as far as TC and the
replication code is concerned it doesn't need to do anything because no
attribute changes are recorded.
Do I just call session.setAttribute("MyObject", myObject) again (where the
myObject reference is the same as before), or do I have to remove and then
re-add the attribute? Or is there something that I have missed?
Also, if you add many attributes during a single servlet call, is the
replication buffered and delayed until the servlet sends its response, or
is the replication attempted each time the session's attributes are
changed?
When does anyone think that the recent replication fixes will make it into
the next official release?
Thanks for any info.
