Re: Enhydra: Information Week Article...


Hi Alex,

    Don't believe everything you read in the press!

    Enhydra 3.0 does not support EJBs but has a simpler and more
efficient framework for building applications as structured
servlets. These structured "super" servlets contain the
object-relational mapping technology, session management,
database connection pooling, etc necessary for an enterprise
application. Enhydra 4.0 (currently very close to functional
completion) does have EJB and implementations of the rest of J2EE
and more.... The Enhydra 3.0 product has been used by Lutris and
many other consulting companies to run some large scale site with
very good performance and success. In fact, I personally believe
that anything other than very careful use of EJBs can lead to a
sluggish web application at best.

    Note that Enhydra 4.0 (named Enhydra Enterprise) is a
cooperation between Enhydra.org and the Jonas team as includes
three services that have their origin with Jonas. They are: EJB
Container Service, Transaction Manager Service and the Database
manager Service. Read the Enhydra Enterprise architecture
description for much more detail.

Regards,

    Paul.

We could fairly easily create and modify shopping carts and other
state-keeping applications. IN PARTICLUAR THE FOLLOWING
<<<However, Enhydra does not support EJB at all.>>> Lutris
recommends running Enhydra in conjunction with Bull Software's
Open Source JoNAS for EJB functionality; while that combination
might be OK for prototyping, it's not sufficient for large-scale
enterprise use. Lutris is working on an EJB implementation but it
is not near completion."
