Configuration Dependencies

[Aaron Mulder <am...@alumni.princeton.edu>]

OK, let's say I have a database pool configuration, a JMS resource
configuration, and an EAR that depends on both of them?  Is there a
way to express that?  You know, have the one EAR plan say that it's
parent is "org/apache/geronimo/System" (assuming that's still best)
but also it depends on "org/something/Database" and
"org/something/JMS" so that it guarantees that those two will be
started before the EAR?

Also, I think David J answered this before, but I can't find the
message.  What's the difference between an "import", and "include",
and a "dependency"?  According to geronimo-config-1.0.xml, it looks
like all three have the type "dependencyType" (though I thought maybe
one was supposed to refer to a different configuration like I'm trying
to do above).

Thanks,
    Aaron

If some of these are supposed to point to JARs (dependency, include)
and some are supposed to point to Configuration names (import),
shouldn't we have two different types?  As it is now, you could do:

<import>
  <groupId>foo</groupId>
  <type>JAR</type>
  <artifactId>bar</artifactId>
  <version>1.0</version>
</import>

Which has no meaning, right?  (Since the import is supposed to refer
to a Configuration)

...
parentId="org/apache/geronimo/Server">
<!-- System should probably only be the parent of the RMINaming 
config-->
<import>
    <uri>org/something/Database</uri>
</import>
<import>
    <uri>org/something/JMS</uri>
</import>
...


Almost certainly Server will be an ancestor of both DB and JMS so you 
can leave it out.

dependency means the jar is in the URL[] of the current configs 
classloader
include means that plus the jar is copied verbatim into the 
configuration itself
import means that the configuration named is a parent of the current 
classloader.
