Re: [WDSCI-L] EAR/WAR Deployment

Joe,

Go ask Bob Cancilla what he thinks of the EAR/WAR concept.

;-)

Seriously, this stuff looks crazy to an old (at least in Internet years)
Net.Data/RPG guy.  No way to deploy a fix to a broken app without taking
down the server?  Well, now WAS-E running on a single node looks really
attractive -- as long as we never deploy an app with a bug in it.

We usually only deploy apps late at night, but every so often we do have to
put in a fix ASAP.  Now I have to take down the entire app server?  Ugh, I
can't wait.

"Tools"?  As in deployment tools?  Some sort of add-on tool that will
deploy
applications?  I don't understand how that would work with WAS.  The only
way I know to deploy to WAS is via an EAR file (or, to a limited degree,
with a WAR file).  There are no other tools, because the WAS folks insist
that they are following the "J2EE standard" and that's all they need to do.

Unfortunately, the more I look into it, the more I realize that J2EE isn't
really standard for business applications.  No concept of net change
deployment, no ability to hot install without bringing down the server, and
now I find that there's no way to run a post-installation script.

As far as I can tell, the J2EE deployment model is pretty much just a way
to
occasionally install a tool.  It certainly is no model for business
application deployment.
