One thing that does help though is that once an EAP line starts, we don't do community releases on that branch. So there should only be two descriptors. We could also call EAP 5.0, jboss 5.2, and EAP 5.1 jboss 5.3 etc if we want to keep them incremental. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536681#536681] Start a new discussion in EJB Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Yep. This will probably mean some other stuff (iiop, snmp) get pulled in, at least the socket configurations. The SBM does provide two other nice benefits: 1. The easy-to-specify "for this server offset base port numbers by XX". Which can be a server-level property in a domain model. 2. A central view to all the port configurations. Which is just a view on the domain model; doesn't mean they all need to be configured in the same place. > mod_cluster.sar, > jboss-cache-manager.sar, > jgroups-channel-factory.sar, > deploy-hasingleton-jboss-beans.xml, > farm-deployment-j-b.xml, > hajndi-j-b.xml, > hapartition-jboss-beans.xml, - Need a cluster domain metadata model mod_cluster is a bit of an outlier, as it doesn't require any sort of intra-cluster communication; can be applied to a server-group. > jbossweb.sar/server.xml, > ejb3-connectors-j-b.xml, > remoting3-j-b.xml, > remoting-j-b.xml, > xnio-provider.jar - Need a connector/transport domain metadata model Leave other server.xml stuff (e.g. valves) out of scope? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536672#536672] Start a new discussion in Management Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-dev-forums] [Management Development] - ProfileService SPI impacts of domain.xml

David Lloyd [http://community.jboss.org/people/david.lloyd%40jboss.com] replied to the discussion "ProfileService SPI impacts of domain.xml" To view the discussion, visit: http://community.jboss.org/message/536668#536668 -------------------------------------------------------------- Also from the sound of it, it sounded to me like what goes into the domain.xml file should be a layer separate from any deployment DSLs we have (jboss-threads.xml, jboss-logging.xml, jboss-xnio.xml, jboss-remoting.xml are mine so far). If we constrain what goes into the deployment DSLs (which are natural extensions of how the service is installed, not managed) by what goes into the management-oriented domain.xml, we're going to have a hard time carrying that off in a way that doesn't suck. Instead it would be better to have a parallel management-oriented schema (or schemas) which act purely as an override set for what's been installed - though it's going to be really ugly trying to just slap that on top of what we have today. I'd rather do the work of reimplementing all these deployers with a nice, well-thought-out API than be faced with the prospect of hacking anything more on top of them (I think this paradigm is already at its complexity limit before it becomes untenable). -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536668#536668] Start a new discussion in Management Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

The means by which the threads DSL is mapped from XML to a BMDF is purely an implementation detail. We probably don't have a lot of alternatives, but the whole process of going from XML to object model via XB, and then to BeanMetaData via BMDF is pretty clunky. I'd like to at least keep the door open to alternatives, so hopefully we won't be locked too tightly into this model... -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536667#536667] Start a new discussion in Management Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-dev-forums] [Management Development] - To scope or not to scope (domain.xml)

by Brian Stansberry

Brian Stansberry [http://community.jboss.org/people/bstansberry%40jboss.com] replied to the discussion "To scope or not to scope (domain.xml)" To view the discussion, visit: http://community.jboss.org/message/536664#536664 -------------------------------------------------------------- Getting to what you describe shouldn't be a huge hurdle; things already largely work this way in AS 5, it's just that the core JGroups and JBC related services, like everything else, are in their own config files. People don't configure a JGroups stack in container configuration files or annotations; at most they indicate what named cache config to use from a centralized set managed by the CacheManager service; that cache config specifies the name of the JGroups stack to use, which again comes from a centralized set from the ChannelFactory service. Those centralized sets are logically under the control of an admin. The stuff I was talking about when I said "the details of what needs to be configured are often disparate between different services, so I'm not sure those configs can profitably be externalized into some common configuration element" was things like load balance policies for remote EJBs, eviction configurations for entity caches, etc. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536664#536664] Start a new discussion in Management Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
