问题 I have been looking for some time for this and I can't seem to find the answer. I am using Spring RMI remoting and I would like to use annotation configuration.

问题 I have set up a client/server project using Java RMI. Below I show parts of the implementation. I launch the server using ProcessBuilder processBuilder = new ProcessBuilder("cmd", "/C", "start /B java -jar myServer.jar --start); this.myProcess = processBuilder.start(); I have added a main method to the server which handles the command line call. The server starts and runs perfectly. The client is able to connect and perform as I expect it to. My problems arise when I try to kill the server.

﹥>﹥吖頭↗ 提交于 2019-12-10 12:19:00
问题 I implemented RMIService using Spring RMIServiceExporter running at port 4099. When I start my Jboss , RMI Service is getting bonded to 0.0.0.0:4099 instead of 127.0.0.1:4099. I tried different parameters -Djava.rmi.server.hostname=127.0.0.1 -Djava.rmi.server.hostname=localhost -Djava.rmi.server.hostname=localhost.localdomain along with -Djava.net.preferIPv4Stack=true parameter. Started Jboss with -b 127.0.0.1 Its always getting bonded to 0.0.0.0:4099 . I check it using >netstat -anp | grep
