Yes and no. There is an overloaded constructor with 4 params; the third is the host name and accepts null: | <constructor> | <parameter>TransactionManager</parameter> | <parameter>socketProcessId</parameter> | <parameter><null/></parameter> | <parameter>10001</parameter> | </constructor> | ServiceBinding actually exposes two getters related to the hostname passed to the constructor: String getHostName() -- simple getter InetAddress getBindAddress() -- derived from hostname The first is a simple getter of what's passed in; the second is derived from hostname: this.bindAddress = InetAddress.getByName(hostName); InetAddress.getByName() will return the loopback address if passed null; so in your case calling getBindAddress() will return the loopback address, not null. That could probably be changed to return null; I didn't think about it much when I rewrote SBM; just left in place the existing behavior. Of course, what getBindAddress() returns only matters if someone invokes on SBM asking for it, which I imagine JBossTS won't be doing. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4173097#...
