> In a blueprint descriptor, it's possible to use blueprint-ext to use Java System variable (the ones passed as argument using -Duser=$USER) and used with something like:
> {code}
> <ext:property-placeholder placeholder-prefix="$[" placeholder-suffix="]"/>
> ...
> <bean ...><property name="user" value="$[user]"/></bean>
> {code}
> In the org.apache.aries.blueprint.ext.PropertyPlaceholder, we do:
> {code}
> v = System.getProperty(val);
> {code}
> Additionnaly, it would be great to do System.getenv() to access the OS env variables, and so being able to do:
> {code}
> <ext:property-placeholder placeholder-prefix="$[" placeholder-suffix="]"/>
> ...
> <bean ...><property name="user" value="$[USER]"/></bean>
> {code} 
> where USER has been set with something like this, for instance:
> {code}
> export USER=my
> {code}
