Hello,
My name is Ken. It is my first post to this list.
I had searched many solutions before and Thank you for this list.
I have a question about WO app's instances and their integrity.
I am considering to process multiple http requests by multiple
instances of WO app.
Each instance can (and should in most cases) be configured to process
multiple simultaneous requests. The simultaneous part becomes single
threaded at the point of changes to the object store (usually
associated with database access).
When I update some data in db from one instance,the changes can be
updated automatically for all the instances?
Or should I notify something to other instances of same app and
fetch fresh data manually?
This situation can be occured when developing a site with multiple
instances and admin app for the site.
The integrity through the instances are maintained atuomatically by
WebObjects?
If it is maintained automatically,is it true for WO app without
session ids in URL and with the ids in cookie?
The location of the IDs has no effect on this.
Could anyone answer my questions?
By the way I think WO can still be a main stream tool for Java
developers
if WebObjects's core could be opensource
I can confidently assure you that this will not happen.
or replaced by other DAO tool easily and stably.
Why? EOF rocks. I have looked at the other tools and none offer a
compelling advantage over WO. One of the real benefits of WO is that
is is single source from end to end. There is no need to use
frameworks to glue frameworks together to achieve your goals. It is
sane, consistent, and mostly free of surprises.
If managing graphs of data and locks are required I would like to do
without EnterpriseObject.
Again, why? You are discarding the _best_ part of WebObjects! Why
not just use Tapestry and some other frameworks?
I think Implementing WO app with opensource DAO can be productive
and high-performence today.
Uh, it is productive and high performance as it is. Adding an open
source DAO will only serve to make it worse.
But I would like to use current code by EnterpriseObject if I
don't need to manage the integrity of instances manually.
