I'm trying to set up a precedence for setting properties as follows:
command-line-->environment-->file.
In searching the archives for some information about setting properties
I saw the following statement which didn't seem accurate to me:
>> I would like to define default properties in a

> <property name="my.desired.prop" value="${env.WHATEVER}"/>
> <property file="default.properties"/>
>

Now I'm fuzzy on the whole property thing, but it seems like
<property name="my.desired.prop" value="${env.WHATEVER}"/>
Would set "my.desired.prop" to the STRING "${env.WHATEVER}" if WHATEVER
was not a defined environment variable. Therefore, any attempt to set
"my.desired.prop" in the "default.properties" file would fail because
"my.desired.prop" would already be set.
Am I off base?
