smooth application upgrade/versioning
-------------------------------------
Key: GERONIMO-557
URL: http://issues.apache.org/jira/browse/GERONIMO-557
Project: Apache Geronimo
Type: New Feature
Reporter: David Jencks
There have been several requests for the ability to change fairly fundamental
bits of application configuration at runtime, such as which resource a
resource-ref points to. Currently the only way to do this is to redeploy the
reconfigured application, and changing this would break a lot of our
implementation and some of our philosophy.
Perhaps a better way to approach this kind of problem is to version
applications, and have a process for seamlessly switching between versions of
an application.
So, to change the target of a resource-ref, you'd configure a new "copy" of
your app with the new target, deploy it, and undeploy the old version.
