Zabbix Java Gateway connects to the following url:
url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://" + conn + ":" + port + "/jmxrmi");
But in certain case, it is not enough.

On OpenMQ, the url must be:
url = new JMXServiceURL("service:jmx:rmi://" + conn + ":" + port "/jndi/rmi://yourhost:1098/yourhost/7676/jmxrmi

service:jmx:rmi://host1/jndi/rmi://host1:port/host1:7676/jmxrmi

In Host Interface configuration, it would be more flexible to be able to specify the URL instead of only the host
