Hi Eric,
the troubles with adding Excalibur and Phoenix is the library avalanche and the existing Fulcrum services will never ever run within a Excalibur and Phoenix container. It sounds like a no-brainer but the Avalon folks never agreed on what to put into the Avalon Context - the Fulcrum services will simply blow up when they access the context to find "urn:avalon:home" since this Merlin specific.
On the positive side I just hacked together YAAFI bootstrapping with Avalon Context mapping - this theoretically allows YAAFI to be embedded into a Phoenix and Fortress container and running any Fulcrum or Merlin services. I have a JAMES installation (=Phoenix container) with embedded YAAFI for digitial signatures to play around .....
The only remaining issue is that I don't know if there is cascading lookup() implemented in Excalibur. E.g. if a component implements a ServiceManager interface you could delegate the search if you own container hasn't found anything and a proper sematic ... any comments from the Excalibur community?!
Tommorrow I code
+) the Avalon Context Mapping for service components - this allows running a cornerstone and excalibur components within YAAFI - at least in theory ... :-)
+) the Fulcrum Reconfiguration Service - I think the easy way to go is to monitor the componentConfiguration.xml and trigger a reconfiguration when the timestamp has changed. It is not a universial solution but solves at least my reconfiguration needs - better than nothing.
BTW - any objections to replace JCoverage with Clover reports?!
Cheers,
Siegfried Goeschl

Sounds great!
I won't be able to help too much on the coding side, but I am definitly able to help on the integration side of things using Gump! I am going through and debugging the current set of Fulcrum errors.. :-)
If the Excaliber folks can lend a hand, we may want to think of setting up two gump projects, one running under Excaliber, the other under Yaafi. Or, look at how our unit tests can be smart and run twice, once under each container. Maybe look at adding phoenix as well?

Subject: Plans for Fulcrum release ....
Hi folks,
within the next 4 weeks I want to cut a new release of Fulcrum for Turbine 2.4.x
RECENT FULCRUM CHANGES ===========================================================
1) there is a new Avalon container called YAAFI (Yet Another Avalon Framework Implementation) to run the existing Fulcrum services. YAAFI is
light-weight Avalon container to be embedded in other applications and comes with litte baggage in terms of dependencies. It is intended as replacement for the depecated ECM and Merlin Container.
2) Fulcrum HsqlDB Service to embed a HQSLDB server in your application
3) Fulcrum ResouceManager Service - a facade for accessing resources currently file system
4) Fulcrum Groovy Service - allows execution of Groovy scripts with access to the Avalon infrastructure
PENDING FULCRUM CHANGES (NOT COMMITTED YET) ===========================================================
1) YAAFI improvements
1.1) improved bootstrapping of YAAFI
1.2) transparent decryption of configuration files based on JCA/JCE
1.3) support for <component-type> to specify the container type to be expected by the component. This allows for reuse of existing services written for Excalibur, Phoenix or Fortress
1.4) support for <container-type> to allow YAAFI to be embedded in a Fortress or Phoenix container, e.g. JAMES
2) Fulcrum PBE Service provides a service for Password Based Encryption based on PBEWithMD5AndDES/PBEWithMD5AndTripleDES.
3) Fulcrum XSLT Service - intgration with DOM4J and Fulcrum ResouceManager Service. This improved service will not be backward compatible
4) I'm tinkering with automatic reconfiguration of YAAFI using a dedicated Fulcrum Reconfiguration Service. This service would monitor the componentConfiguration.xml and reconfigure YAAFI if the file has changed. This allows automatic reconfiguration without any client/server
communication
5) a Turbine YAFFI Component Service to bootstrap YAAFI within a Turbine
application
6) Fulcrum ResourceManager Service provides transparent encryption/decryption of resources.
REQUEST FOR HELP ===========================================================
1) Help from the Excalibur community would be greatly appreciated to kickstart component compatibilty testing
2) Any who would like to work on bleeding-edge Fulcrum/Turbine?!
Thanks in advance
