Hi Andrew,
(Sorry for referring you as Andrews, earlier :) )
Let me tell you the high-level idea (and I am going to
blog about it once I get a breather).
In the domain.xml, we can store a token almost anywhere, like
this:
<domain>
...
<configs>
<config name="aconfig">
<java-config ...>
<jvm-options> ${TokenForDashD} </jvm-options>
...
</java-config>
</config>
</configs>
<servers>
<server name="server1" config-ref="aconfig">
...
<system-property name="TokenForDashD" value="Foo"/>
</server>
<server name="server1" config-ref="aconfig">
...
<system-property name="TokenForDashD" value="Bar"/>
</server>
</servers>
...
</domain>
Hope you are with me.
Now, when "server1" starts, it will take value of "TokenForDashD" to
be "Foo", whereas "server2" will take it as "Bar" passed to the Java
command invocation that starts the server instance!
Is that what you are not looking for?
Sorry if I misunderstood.
If this is what it is, I will document this as a blog and then
make sure our official documentation reflects this.
Thanks and Regards,
Kedar
PS: Like I said, there are a few bugs in this and we will fix them soon.
