Hi,
Sorry to overwhelm you with more documentation, but the sequence of
operations is provided in Configuration Roadmap for High Availability of
GlassFish Server
<
http://docs.oracle.com/cd/E26576_01/doc.312/e24931/concepts.htm#abfca>
in the product documentation. Also have a look To Install and Configure
the GlassFish Server Cluster
<
http://docs.oracle.com/cd/E26576_01/doc.312/e24937/use-cases.htm#gkybs>, which
is a worked example that covers the relevant steps for a 2-instance
cluster with the DAS on a 3rd host.
I'm not sure why install-node gave you a null-pointer exception. If you
can use SSH to log in to the remote host with being prompted for a
password, install-node should work.
