Is there a domain-concet in JBoss?

Hello!

We are migrating a webapp from wls 8.1.4 to JBoss 5.

In the app we got a tag that writes domain-name and server-name in a footer.

The values came from wls-framework like:

WebAppComponentRuntimeMBean webAppMBean = (WebAppComponentRuntimeMBean) servletContext.getAttribute("weblogic.servlet.WebAppComponentRuntimeMBean");
WebLogicObjectName wlName = webAppMBean.getObjectName();
String servername = wlName.getLocation();
String domainName = wlName.getDomain();



I think I have solved the server-name from JBoss-framework

      ServerConfig serverConfig = ServerConfigLocator.locate();
      String domainName = serverConfig.getServerName();

But I can not find the correspondence to the domainname in JBoss.

So first question is: is there any domain-concept in JBoss?

Second: if yes in first, how to I get the domain-name in JBoss?

Best regards
Fredrik
