Hi Can we have Multiple and different RMI exposed Methods using Naming.Rebind("A name for access to Method",new ImplementedInterfaceClass) in a single Machine and running in the same time? I tried to have such Methods, Running first main is ok and RMI method is successfully is registered ,but always when I run the second main, I recieve error: Exception in thread "main" java.rmi.server.ExportException: Port already in use: 1099 how can I get multiple RMI running with those desired conditions?
