Persistence [Hibernate]
As posted before, I have implemented a PersistenceService in Merlin, which
is accessible through Merlins context and uses the Hibernate OOR mapping
tool.
If you are intrested in, you can download the service and some example code
from
http://www.merlin.softwarefabrik.biz/tutorial/persistence/background.htm
I have also added some very limited doc. It should help to dive into the
code.
Thanks
Andreas

RE: Avalon Context (was Re: Persistence [Hibernate])
Posted by andreas oberhack <de...@softwarefabrik.biz>.
:-) right. It's just the rest of my early days of evaluating the context
class. (tutorial)
I was thinking about to have a "SystemInfo getSystemInfo()" in the
context, where you could ask for "getPartitionKey()" etc.
All the best

Avalon Context (was Re: Persistence [Hibernate])
Posted by Stephen McConnell <mc...@apache.org>.
Just an inital thought ...
The class ApplicationLayerContext could be simplified. The context class
biz.softwarefabrik.system.merlin.context.ApplicationLayerContext is
derived from the classic Context interface but includes static public
identifiers for the following keys:
public static final String NAME_KEY = "urn:avalon:name";
public static final String PARTITION_KEY = "urn:avalon:partition";
public static final String WORKING_KEY = "urn:avalon:temp";
public static final String HOME_KEY = "urn:avalon:home";
My opinion is that the above key declarations should be moved to the
org.apache.avalon.framework.context.Context class.
Stephen.

Yep - but what do I actually import - of the three downloads - 2 are
examples and one is the persistence stuff - I think the plugin itself is
missing.

It's quite easy. Only extracting the zip and restart eclipse. But there
quite powerful features for updating plugins build in into eclipse. I
followed your discussions about the repository - and I think, it would
be interesting to have a look at the eclipse distribution framework!
Let me just write a small installation guide - it will ease the things!

Jim,
If you're looking for a web server/servlet container that can embedded into
merlin, then the avalon-merlin block has just been offered up as candidate
for the sandbox. It is a solid block implementation of the Jetty web server
and servlet container (http://www.mortbay.org), and provides a hook to allow
any servlets/webapps access to the Avalon ServiceManager for component
lookup. There should be an announcement here and on the avalon users list
soon about its availability.
If you are absolutely set on using Tomcat, then this block will not be of
much interest to you.

Just for completeness I have attached a copy of the block.xml that works
correctly. I would have thought that thread-impl's block.xml would have
included all the runtime dependencies for the DefaultThreadManager.

Could you post the log using -debug.
Quick question - do you really need cornerstone-threads-impl and
excaliobur-thread in your classloader?

:-) no. I didn't upload the plugin yet, because I'm just testing the
installation procedure.
I could give you the current version and if you get problems installing
the plugin - please let me know.
Which version of eclipse are you using? 2.1 or 3.0?
