It's supposed to look like:
<node name="localhost" nodehost="localhost" nodehome="${com.sun.aas.installRoot}">
But we're having some problems with defaulting and values getting
squashed out that I haven't gotten to the bottom of yet.
If the general questions is: I have a Server instance, how do I find what
host it is running on? Then the answer should be this method:
com.sun.enterprise.v3.admin.cluster.RemoteInstanceCommandHelper.getHost(Server)
but it looks a bit wrong at the moment. I will look into it today.
