Just had the opportunity to read this article by Colm a couple of weeks ago:
He does a good job of explaining "why not?" for the standalone listener.
Thanks, Paul. I notice that the link in cdivilly's article that you reference directs to the Open Source version of GlassFish (http://glassfish.java.net/) not to the Oracle GlassFish server (Oracle GlassFish Server | Oracle). Is that an oversight?
If it is possible to satisfy Oracle support by plugging into the Open Source GlassFish server then we have no issue. To cover all our CPUs from Dev to Prod with failover servers, we are looking at hundreds of thousands of dollars.
To clarify, does the support policy require Oracle Glass Fish server?
