No
when myproperties-jboss-beans.xml are placed in deployers dir they are available before
the ear gets deployed
ok it finally works somehow :-)
I supposed to use the supply/demand scenario with both myproperties-jboss-beans.xml and
myapp.ear in deploy dir but it doesn't work since JAXB unmarshals myapp.ear/my-ds.xml
descriptor before SystemPropertiesService reaches its configured state and thus
* would like to use
<max-pool-size>${myapp.db.maxPoolSize}</max-pool-size> in myapp.ear/my-ds.xml
* ends up with maxPoolSize == 0
2011-01-03 14:45:56,810 DEBUG (main)[org.jboss.system.ServiceConfigurator] MaxSize set to
0 in jboss.jca:service=ManagedConnectionPool,name=Ora11DS

Ah, now I actually see/understand your problem -- at least I think so. :-)
My previous suggestion is wrong.
What you need is the following, in theory at the moment.
* deployment myapp.ear must depend on SystemPropertiesService, but in PARSE stage
** this way ear' -ds.xml will be parsed with required system properties
We already have proper mechanism in place for this,
see jboss-dependency.xml ( http://community.jboss.org/docs/DOC-13178
http://community.jboss.org/wiki/JBoss5custommetadatafiles),
but it will need minor adjustments.
See dependency-deployers-jboss-beans.xml in deployers/,
all three jboss-dependency.xml related deployers need a change of stage.
<property name="stage">DeploymentStages.PRE_PARSE</property> <---
pseudo code
Then adding proper jboss-dependency.xml into ear' META-INF should do the trick.

Good attempt, seriously!
You need to change this:
<item whenRequired="PreParse"
dependentState="Create">istep:type=Properties,name=SystemProperties</item>
whenRequired cannot be PreParse, as we're there right now - when parsing - hence
already past it.
Change it to Parse. And you can drop the dependantState attribute, by default it should be
Installed, which is fine.
Let me know if this works then.
Otherwise I'll give it a try. ;-)

yeah great it finally works !!! thank you very much !
<item
whenRequired="Parse">istep:type=Properties,name=SystemProperties</item>
was the last step on the "deploying of myapp.ear/my-ds.xml with
${max-pool-size}" journey :-)
looking back on the interesting evolution of this forum thread there are a plenty of
usefull hints which may be worth noting in a separate wiki article
I'm willing to write it down
btw why whenRequired="Parse" ?
Parse is a deployment stage but whenRequired attribute representation in
DependencyItemMetaData class is a controller state ?
public class DependencyItemMetaData implements Serializable {
private Object value;
private ControllerState whenRequired = ControllerState.DESCRIBED;
private ControllerState dependentState;

Yeah, that would be very helpful!
Post the link here once you're done.

state ?
public class DependencyItemMetaData implements Serializable {
private Object value;
private ControllerState whenRequired = ControllerState.DESCRIBED;
private ControllerState dependentState;
DeploymentStage is just more natural
representation of MC state wrt deployments.
It eventually gets turned into ControllerState, but that's impl detail.

I plan to describe the pitfall while deploying system properties and using them
inside both j2ee and jboss deployment descriptors of custom deployments
then emphasize ds-xml, recent fixes in connector and finally necessary changes in both
jboss core config (dependency-deployers-jboss-beans.xml) and deployment
(META-INF\jboss-dependency.xml)
