I disagree on this one. Embedding frameworks enables you to be
independent of the version of WebObjects installed on the target
machine. Considering the cost of disk drive (<1$/Gb) 10Mb is a
negligible it is save you debug time. Even the upload time is very
small if you tar your application before uploading.
Hmmm. Uploading about 270 megs more over a cable connection for every
deployment is negligable? This would be the estimated difference for
me embedding all (including the WO frameworks) frameworks in each
application. A full deploy here would mean ten applications, WO
frameworks and Wonder and a lot of external Jars included in any of
them.
And I don't have any benefit from that, because *I know for sure* that
the WO frameworks installed on the deployment environment are the same
I have on my local dev machine. And we do deployments fairly often. It
might be okay for you as you are probably on a pretty fast company
network. ;-) I am not as I normally do deployments in the evening from
home over a fairly slow cable connection.
Don't get me wrong, this is not about disk space which I normally have
enough on the app server, this is about totally unnecessary redundancy
in my set up. And I bet this is similarly true for a lot of WO
developers.
What I really see is the benefit of embedding "changing" frameworks
with each app, as this has the advantage that you can deploy different
apps with different versions of the frameworks. It all depends on the
requirements and from what I have seen in the past, the need to embed
the own frameworks is often given, but the need for embedding the WO
frameworks was never there. But this might start now as nearly
everybody still uses WO 5.3 and Leopard comes with 5.4 AND the updates
are not independent. Or are they?
Let's put it that way: there might be situations where it makes sense,
but I doubt that these situations are very common.
