Just for reference, we intent to include the James and Tomcat blocks
(enabling the introduction of email and web gateways to the OSM platform).
Getting symcronization between Avalon/Phoenix/James/Tomcat is to say the
least a painful experience. One of the principal "pains" in this process
is the lack of support in Avalon for lifecycle components "install",
"upgrade", "degrade" and "uninstall". For example, when a new version
of James is released, and the new version contains an updated assembly.xml
file - its a pain because I have to go though and figure out what needs
to be changed in my "James block that I'm declaring to my customers" -
actually this is a complaint - centralised handling of configurations
in Avalon/Phoenix doesn't work when attempting to build and deploy real
applications with cross-vendor-block dependencies. Its just too painful.
I would prefer to see a clear and distinct install phase in which different
blocks publish default configuration profiles ... during this phase, and
block should be able to validate an exiting profile (preferably marked with
a version identifier) and incorporate existing information into a new
configurations. On the Tomcat block front - we have encountered lots of
problems - inconstancies between CVS content on the apache site and build
files (i.e. build files include targets to create an avalon block but
the source code does not exist under the CVS) and a few horror stories when
attempting to build the Tomcat block (which is not to say that we have
given up on the Tomcat block - its just that its we are at the point of
deciding if we do this ourselves or wait).
Cheers, Steve.
