Re: [jboss-as7-dev] Configuration conundrum with Express
Thanks. I'll check against the attributes I'll need and raise issues to
address those I find missing.
One issue I see is that we are only looking to System.getProperty(name)
for the value of an expression in the org.jboss.dmr.ExpressionValue
class. The expressions I'm typically using need to be queried using
System.getenv(name). Would it be ok to fallback to a System.getenv(name)
if there is no System.getProperty(name) value found? This would require
an update to the dmr project.

See example below of reading a resource and then setting an attribute

an expression value. This will work properly on master when I'm done today.
Note that not all attributes support expressions (most don't). For those
that do, the :read-resource-description content for the attribute will
include:
