Hi Otis,
Thanks for your feedback. I think it's effectively a good question ,
what is realy SaaS ? I think, but it's just my opinion, that's just a
software distribution business model for editors. So I think you never
found SaaS specific functionality in any framework.
For me, the real question is what do you need to develop SaaS
application ? and that's the goals of jspirit to give some answers.
For me needed functionalitiy are clearly Multi-tenancy implementation
with maximum flexibility, distributed model and clusterisable
architecture to support the need of high-avaiilibility and scalability
of SaaS applications.
Saas need fast response to evolution need, it's the goal of jspirit
programming model and architecture.
In my opinion, we have to focus on functionality to made SaaS in this
project and not on SaaS-functionality.
We try in this project to integrate full open-source application stack
to help anyone who wants make SaaS so there is generic functionality., i
think it's normal. The goal is to make a coherent integration framework
with to let developer focus on business code.
So I think we should name jSpirit "integration framework for creating
web multi-tenant application".
I will make a translate of the slides in the next day, perhaps it will
be more clear for all.

Hello Grégoire
Thanks for the exhaustive feature list and
http://wiki.apache.org/incubator/JSpiritProposal . I'm trying to identify
Saas-specific features from that list. Most of them sound relatively generic,
not SaaS-specific. Is my interpretation correct? The only ones that jump at me
as being useful in SaaS context are the Multi-tenant ones (e.g. Multi-tenant
interceptor for determining tenant context based on full qualified domain
name), some of the REST and authorization/authentication ones. This is not a
criticism. I'm just trying to understand what's SaaS-specific and what is more
general here.
Also, maybe it's just me, but I can't tell what jSpirit really *is* today from
the Proposal on http://wiki.apache.org/incubator/JSpiritProposal . I see a
bunch of technologies mentioned, but if I were looking at jSpirit to figure out
if this does something that I need, I couldn't tell. Again, maybe it's just me.
:)
Oh, I see some fresh PDFs on SF. I skimmed them, but my French is
unfortunately, you know .... just not there. :(

Hi Otis and all others,
I will list here current and planned functionality of jSpirit.

Layer, Business Layer, Client Layer
- Java 5 annotation and auto-injection based lookup of services
- Classpath scanning for auto-discovering components
- Modular and plugable architecture : automatic activation of modules in
the classpath, ready for seamless integration

Geronimo Transaction Manager), and implicit demarcation (explicit demarcation
is always possible)
- [in progress] AOP interceptor on top of each layer
* Integration Layer
--------------------------------------------
- Implementation of abstract integration services and abstract persister
based on JPA technology
- Maven plugins for code generation of integration layer from xml
description of component business model : generate persistent class, access
services, queries, constraints, JPA annotation, lucene indexation of business
model

Grégoire,
Could you please point us/me to some information about jSpirit
funcitonality
that is SaaS-specific?
Understanding that may help people figure out what jSpirit brings and does.
For example, if I use jSpirit, which SaaS-specific functionality does a
developer not have to develop? What functionality comes out of the box?
etc.
Thanks,
Otis

Subject: New project proposal
Hello,
I'm the project leader of an open-source project called jSpirit.
The goal of the project is to create an open-source platform to develop
efficiently enterprise class lightweight J2EE application for SaaS with
Multi-tenant support. The code is available here
(http://sourceforge.net/projects/jspirit/). The platform focuses on the
technical aspect of SaaS and Multi-tenant.
I would my project to pretend becoming an Apache Incubator project, and I
need
help to do this. I think this kind of platform could interest a large
community. The goals are to provide open-source application stack (focuses
on
apache project), tools to develop efficiently, an architectural model for
enterprise class application, methods for project management, and an
integration framework for "rescuing" application developper from J2EE and
multi-tenant complexity.
The project is already used by a french company as a foundation of her
ERP
(Husson Ingenierie, http://husson-info.fr), it's the base of the community
yet.
I want to develop my professionnal activity around this project, so it's
perennial project, I think.
Is there anyone intersted by this project ?
Best Regards,
