Subject: [wsrp-wsia] Issue #19 - Hints for InitEnvironment
- From: Andre Kramer <andre.kramer@eu.citrix.com>

Since
I originally raised #19 and as I've not seen any follow on discussion on our
infamous initEnvironment()/groupID topic since last week's call, I would like to
make more concrete a proposal made in the call's lengthy groupID
discussion.
7.1.1.
states: "Since Consumers will not know what entities could benefit from any
Producer mediated data sharing, they SHOULD place all entities from a Producer
within a single group until a reason is identified for specifying a separate
groupID".
I agree this is enough to support JSR168
application/shared session scopes by providing each user with a
separate (i.e. one) load balanced environment via the groupID argument to
initEnvironment(). However, an extra hint from the producer is required in
order to load balance a user's Portlets across multiple JSR168/Web Applications
and nodes:
(Proposal) A producer could include a "String
preferredGroupID" (as an optional hint) in an EntityDescription element (or
possibly in the EntityType meta data). Consumers could then discover this extra
performance related meta data using getEntityDescription() and use it for the
groupID in initEnvironment(), as described in 7.4. I believe they are not
required to do so, but I would still say "SHOULD" rather than "CAN", which is
why this may be more than just a "vendor" extension for
JSR168.
Hope
this helps us further the discussion,
Andre
A new
version of the issues list.
Changes:
1. We now
have a manageable number of open issues!
2. The
date whereby a tentative resolution is considered final (due to lack of
interest) is now in the list, and not one of the secondary headers. This will
help us browse through the list and see whether anything needs to be
discussed. BTW, I always set it to two weeks from the time I get a tentative
resolution from anybody, and always send an email on that regard to
the list to see whether anybody is interested in contesting that
resolution.
Cheers,
Gil Tayar
