Cannot connect via JMX to servers managed in domain mode

I was trying to connect remotely to Infinispan servers run in domain mode. I was following instructions that worked for me with Wildfly 10 (e.g. at https://goldmann.pl/blog/2013/04/16/jmx-connections-to-jboss-as/ ), but that didn't work with Infinispan servers. There is no documentation about how to do this and since it's not working the WildFly way, I mark this issue as bug.

After investigation, we (many thanks to lthon@redhat.com) found out that it doesn't work with ISPN server, because WildFly uses http upgrade for this purpose via http-connector. The connector (by default commented in the domain.xml) requires undertow subsystem to work, however, ISPN server doesn't have it.

There are two possible solutions:

• add the undertow subsystem. The modules/ directory already has the jars, therefore it's only needed to add following to domain.xml and than you can connect to the server via JMX URL service:jmx:remote+http://localhost:8080. However, I wouldn't prefer this solution.

  <subsystem xmlns="urn:jboss:domain:undertow:3.0">
      <buffer-cache name="default"/>
      <server name="default-server">
          <http-listener name="default" socket-binding="http"/>
          <host name="default-host" alias="localhost"/>
      </server>
      <servlet-container name="default"/>
  </subsystem>
  

• second solution is to create remoting endpoint just the way it was before in JBoss AS 7, therefore add following to the domain.xml and then connect via JMX URL: service:jmx:remote://localhost:4447. This solution should be preferred IMHO.

   <connector name="remoting-connector" socket-binding="remoting" security-realm="ApplicationRealm"/>
  

  <socket-binding name="remoting" port="4447"/>
  

I will soon issue a PR with the solution number 2 and appropriate update of documentation. Of course, these options should be disabled by default, by I think it would be nice to have them commented in the domain.xml.
