Hello; I am a lowly Java EE user who is late to this discussion. I
happened to have raised a similar set of issues over on the Glassfish list ( and
following). They just referred me here.

I don't want to wade into an area that has already solidified, or otherwise
upset the apple cart. Is this a good place to talk about
customization/configuration of .*ar files in Java EE?

Briefly, I'm looking to see what can be done in Java EE 7 (or beyond) to
support managing the configuration and customization of an .ear file such
that the .ear file could itself be left unmodified. A secondary goal would
be to follow the general spirit of something like java.util.logging where
the customization mechanism uses files/resources by default, but can be
programmatic if that's really what the user wants. The driver behind all
this is our customers' frustration at all the zipping and unzipping they
have to do to customize our .ear file.

I'll leave things there to start just in case I'm in the wrong place or
this isn't the time to discuss these issues. I'm also happy to flesh out a
proposal in more detail offline. I just wanted to see if this was a good
spot to kick off discussion.

Thanks for your time (and attention),
