[weld-dev] My take on Spring3

[Piotr Steininger]

I am still a bit on the fence about campaigning against Spring. I think
there is far more to be gained from promoting CDI, Weld Extension, Seam 3
and the EE 6 profile (with positive messages), than jumping into a debate
with gung-ho Spring believers. From what I saw in my consulting engagements
people who used Spring for a while are stuck in a specific mindset of
application development. For them anything beyond singleton bean wiring on
app startup does not exist or is too mysterious or scary. Yes, it does sound
funny, but I once had the same mindset, but I saw the light ;). I converted
to Seam thanks to so many examples and great books like Dan's Seam in
Action.

So if our goal is to entice the "not-yet-lost" souls, then we have to send
more messages that are pro-Weld, and not necessarily against Spring. How to
do it? In a few ways. First, excellent and exhaustive documentation. I think
Gavin, Pete, Dan and the community has done an awesome job in that arena,
and have set a golden standard. Second - example projects. I think nothing
shows the prowess of a technology stack than a real proof that it works,
works well, integrates with other key technologies (JSF2, JPA, BPM, etc),
which are part of the Enterprise application ecosystem. These examples
though need to go above and beyond the simple ones already out there (we
need the simple ones too) - something along the lines of the Photo Album for
RichFaces. Third, tutorials, articles and blog posts detailing the
aforementioned examples - in another words - creating the hype and
excitement about the CDI's programming model, and the ease of creating
powerful apps in an elegant and concise way.

But at this point, there are still a number of important pieces missing,
like the Weld extensions and Seam 3 modules, which provide integration with
key technologies for business apps (i.e. BPM or Security) or complement
these technologies. These are needed to create the example projects, which
are essential as the meat of the article to be written about Weld and Seam.

My key goal is to build an enthusiastic community around CDI, rather than go
after Spring. I think Gavin has a better handle on disproving any allegation
against CDI or anything bogus about Spring. I simply don't have the
technical know-how, just an implementer experience.
