According to JBoss documentation:
In managed domain deployments are associated with a server group.
Deployments will be provided to any server that belongs to a
particular group.
...the multiple servers in common server group become the single one virtually.
But how does JBoss choose the target actual server for deployment?
For example, i have two different vps servers with JBoss running, which are combined to the single main-server-group. Then which vps server will actually host the application by following command?
[domain#localhost:9999 /] deploy ~/Desktop/test-application.war --server-group=main-server-group
'test-application.war' deployed successfully
The application will be deployed to both servers.
If you were to go to http://server1:8080/MyApp you should see the same as if you went to http://server2:8080/MyApp
The reason for this is that you would normally have a web server or proxy to load balance between the two servers. If you want to have two separate servers which don't have the apps deployed to each, then put them in different server groups or, a better solution would be to run JBoss in standalone mode, rather than domain mode.

I have been trying WildFly as application server for a production enviroment, however I have few doubts that I can't answer with the documentation or previous questions.
In the domain mode using the same machine, I have created two server group that are containing one server each one, this is with the idea of isolate two different production enviroments. The problem with the dataSource, is that obviously I have to create them in the profile associated to the server group, but always that I create a new dataSource I need to restart de group, this is a problem since I can't restart the servers for doing this.
Is there a way to do this in a more friendly way?
I'm currently using WildFly 13 and the HAL console to admin the servers.
I have a Websphere profile which has 2 nodes. I can login into the
https://localhost:9044/ibm/console/
and click on the Application Server, I can only see the Node02 applications as the header is
Cell=Node02Cell, Profile=AppSrv02.
Actually in the
c:/IBM/Websphere/profile/,
there are 2 servers AppSrv01 and AppSrv02, both are startup. May I know how to see Node01Cell server and applications?
In addition to Alasdair answer, in case of WAS base, if you want to manage all servers on the same host you can use Admin Agent profile. You would need to create new profile and register your profiles in the admin agent.
Then you will be able to manage both servers via single console, selecting during login, which server you want to manage.
For details see Setting up the administrative agent environment
I'm assuming from your question that the two servers are in different sub directories of the one quoted. Assuming you are using the WAS base product there is no way to see both profiles in single admin console at once. You can use WebSphere Application Server Network Deployment and federate two different profiles into the same cell at which point you could see both of the servers. With base you can use the admin agent to manage two profiles on the same machine, but you would manage each profile individually.
I am assuming that you installed two stand-alone application server profiles with individual console. To create a clustered or multiple node setup, you will need to install a Deployment Manager profile as your main console then add two nodes to be federated by the Deployment Manger.

I have a server on which should running several Demo Applications on JBoss. The applications are exactly the same like each other. Only the ports for the web access, used database and so on should be differ (so each customer has an separate access to his demo system). All demo applications should be running on the same machine / operating system.
Whats the best/correct way? Standalone (with different JBoss instances for each demo application; see also here)? Or the domain mode with different JBoss server/server-groups for each demo application?
This depends on if you want to manage your servers from one location (so called Domain Controller) - it will give you the ability to control all servers (hosts in this case), deploy apps and configure them from one management console. If you need this, you could benefit from Domain Mode. If not, there is no reason why you shouldn't have separated instances of JBoss in standalone mode and control them separately, both options are perfectly fine.
I'm starting an JBoss to use on the development, and I'm using it as standalone.
I read that on the production environment the JBoss should be as a domain.
I searched for that to understand what's the difference between than. But I didn't found any document well explained.
That's not really correct. Standalone is fine for production. It's commonly used in production, especially when you only need one instance of the server.
Domain is used when you run several instances of JBoss AS and you want a single point where you can control configuration from. You can read more about it in the documentation.
Update
The link has been changed to the latest version of WildFly as the JBoss AS 7 documentation has been archived, but is still available at https://docs.jboss.org/author/display/AS71/Admin%20Guide.html#8094211_AdminGuide-StandaloneServer
Standalone mode
each JBoss server has its own configuration
single JVM process
Domain mode
central control of multiple servers
central configuration for multiple servers
It's important to understand that the choice between a managed domain and standalone servers is all about how your servers are managed, not what capabilities they have to service end user requests. This distinction is particularly important when it comes to high availability clusters.
So, given all that:
A single server installation gains nothing from running in a managed domain, so running a standalone server is a better choice.
For multi-server production environments, the choice of running a managed domain versus standalone servers comes down to whether the user wants to use the centralized management capabilities a managed domain provides.
Running a standalone server is better suited for most development scenarios. Any individual server configuration that can be achieved in a managed domain can also be achieved in a standalone server, so even if the application being developed will eventually run in production on a managed domain installation, much (probably most) development can be done using a standalone server.

How can I run ejbs exposed as a web services on the same jboss (version 4.2.3) using different IPs.
For example:
I have two web service locations (two different ejb components) and one server with two network interfaces:
http://192.168.0.1/test/TestService1
http://192.168.0.1/test/TestService2
and I want to have this:
http://192.168.0.1/test/TestService1
http://192.168.0.2/test/TestService2
Thanks
If JBoss is anything similar to websphere in it's architecture, I think you'll have two create to separate server instances and bind each to a specific IP. Then you'll deploy the EJB:s to the respective instance bound to the desired IP.
