[gentoo-dev] Application server deployment eclass?

[gentoo-dev] Application server deployment eclass?

[Dave Nebinger]

Okay, so if I have a servlet to deploy to an application container such as 
tomcat, is there an eclass that I can use to inherit from?

Obviously the webapp eclass helps for straight apache-like deployments, but 
it's not going to help much when deploying to tomcat.

I looked in /usr/portage/ebuild, but nothing jumped out at me...

So how do I get my war file deployed?  Am I left to external tools such as ant 
to manage that for me?

How does such an entity fit within the portage world?

I don't think so.

Well maybe the webapp setup can be configured or added the support for
tomcat too. It is just a matter of paths I think.

I don't think we have any servlets packaged in the tree at the moment.

ant is a helper tool for building java software from sources, hopefully
no-one uses it for package management. I think at the moment people just
 do the management manually, but you need to ask people who actually use
tomcat in production.

If we start packaging servlets, then we of course need a setup for that,
but it is not something the java team is actively looking into. Feel
free to do your own development and we can then integrate it to the
official tree if we find it a valuable addition.

Each J2EE server has its own method for deploying j2ee archives. I don't
think it is easy to create one that supports them all (WebSphere, WebLogic,
Oracle's, TomCat/JBoss, ...).

And anyway, the idea behind such archives is that the deployment itself is
tweaked to the environment itself - there is no way for a "default works for
all" deployment method afaik.

I personally use a Java tool that uses the JMX possibilities of the J2EE
server (if it supports it) to deploy tools, but this is targetted on a
personal environment and mainly used to 
  1. provide a sort-of default method for deploying archives on the
     environment (which uses a single brand of J2EE servers anyway)
  2. automate the upgrading of archives to a new version
