[jboss-as7-dev] make <socket-binding>'s port optional

Hi, I am working on an issue in the domain model for HornetQ cluster configuration[1]. To be configured properly, I want to specify only a multicast-address and multicast-port but not the local port (and let the OS open one). According to jboss-as-config XSD (and brian ;) ), it's correct, the port attribute of socket-bindingType is indeed optional. However, we had multiple places in the code where the port is considered mandatory. I have started to change these places to have a consistent semantic between the XSD and the domain model but I have a test failing and I can't figure out where is the code responsible for that. In my branch, I have configured the messaging subsystem[2] with this <socket-binding> (no port defined): <socket-binding name="messaging-group" multicast-address="231.7.7.7" multicast-port="9876"/> But when I run the test suite, I end up with a standalone file[3] where the port attribute is set to "undefined" <socket-binding name="messaging-group" port="undefined" multicast-address="231.7.7.7" multicast-port="9876"/> Newbie question: where is the code in charge of generating the standalone file from the messaging.xml subsystem? I am not yet familiar with AS7 codebase... AIUI, I need to make sure that if the port is not defined in the model, it is not written to the XML either. thanks, jeff [1] https://issues.jboss.org/browse/AS7-3881 [2] in build/src/main/resources/configuration/subsystems/messaging.xml [3] in testsuite/integration/smoke/target/jbossas/standalone/configuration/standalone-full-ha.xml -- Jeff Mesnil JBoss, a division of Red Hat http://jmesnil.net/
