Mmmm, i think i was not clear in my explanation, let my try it again:
Ok the mail-service.xml file is in /server/default/deploy/ folder. So I will make a copy of this file but changing its parameters, ok. Now i have my altMail-service.xml. How do i make the application to use that file or that conifiguration?.
I simply upload my WAR application via AdminConsole, but found no way to check something about the mail-service configuration it will use or similar.
I suppose that mail-service.xml in that folder is the configuration for the hole instance and all applications installed in it, so i need an specific configuration for my concrete application, if its possible.
Hope you understand me now.
Thank you very much.
