[jboss-dev-forums] [Design of JBoss Transaction Services] - TransactionManager doesnt allow to configure bind address

[jgra@vp.pl]

Aparently there is no configuration parameter to specify bind IP for TM to listen (as far as I now) and TM allways binds to all interfaces on machine.

In JBoss App Srv ver. 4.2 configuration, TM creates 3 efemeric ports with bindings as stated above and it ignores JBoss run cmd address binding option (-b).

Quick look in App Srv sources shows that the problem is not about integration service for App Srv, but lack of such feature in TM Core which use ServerSocket ctor with only port argument.

>From security point of view it should be possible to bind TM to specific address   using some config parameters.
