This is great information!
from what i've read AMX (is similar to JMX) and accomplishes the same functionality
?
DAS is the Domain Admin Server which is enabled when remote admin is requested
?

Subject: RE: How to start the server with a disabled HTTP listener
If you have a default GlassFish install
with just the server instance then you only really have a DAS that you
happen to deploy your apps to.
From
http://wiki.glassfish.java.net/Wiki.jsp?page=GlassFishV2Architecture
Domain Administration Server (DAS).
The DAS, a fully functional Java EE 5 server instance, facilitates administration
for the Domain. All administrative operations (e.g. initiated via the CLI,
GUI, NetBeans IDE, and other tools) are routed to the DAS rather than to
server instances directly. For aggregate operations that encompass more
than one server instance, the DAS will be responsible for broadcasting
administration requests to instances. DAS is able to administer instances
running on remote hosts. When the DAS is not running administative operations
are not possible. No special efforts are made to make the DAS highly available
except for simple watchdog and restart capability. Instances and clusters
in the domain can function normally even if the DAS is not running.
Administrative Client Applications
(CLI, JSR 77, AMX). Administrative clients include the asadmin CLI
(command line interface) utility, and modules that plug into the Studio.
These applications reside either inside or outside the firewall and communicate
exclusively with the Domain Admin Server (and not server instances directly).
All application deployment makes use of the JSR 88 APIs. Configuration
and application deployment are done exclusively via JMX MBeans (some of
which are standardized by JSR 77). These clients clients use JSR160 JMX
connectors to access the DAS. To cross firewalls, the protocol of choice
implemented in the connector is HTTP(S). There is also an MBEan interface
called AMX that exposes all the functionality through API.

Mssr Power:
could you explain what DAS is.. and how it is used (or not) in this context?

Subject: Re: How to start the server with a disabled HTTP listener
It shouldn't be hard to catch the INIT or STARTUP life cycle event, but
if you are using a single instance of Glassfish then you don't have an
operational DAS for your AMX calls to contact and update. Also I believe
that if the HTTP listener was enabled in the configuration then even if
you had a DAS for your AMX calls to connect to it wouldn't be able to stop
the listener from starting since the container doesn't seem to get updates
from the DAS during the INIT and STARTUP stages of it's lifecycle.
But if it is possible I'd also like to know how to get it to work.
Regards,
Vince

Thanks for the answer, but I want to avoid hacking the domain.xml.
I would like to implement the LifeCycleListener interface and on the startup
event,
get hold of the DomainRoot and disable the http listener using AMX.
How do I access the AMX DomainRoot from [i]inside[/i] of the Glassfish
server?
