With RMI on Port 1099 never I've really worked. I've got a webapplication named with Hippo HST. I'm thinking about to run it as an Portlet inside GateIn. On Apache Tomcat the application creates a RMI service on rmi://localhost:1099/hipporepository but Jboss also does create a RMI Service on this Port. Currently I've setted on the webapp for the RMI Service the port to 1199. So I'm asking me now if it would be possible to configure Jboss 5.1 that the webapp could creates there stuff inside the RMI Service from Jboss. So it is possible? And if yes, how could I do it?
