Hi kofemann, I have a c++ rpc server .I want to generate different version numbers for that c++ rpc server from java ..can I use rpcsvc class .is it possible from your code? Example : Program number : 10007 But multiple versions(1, 2,3,4 up to 32 versions ) on different machine address( 4 IP address) For the same c++ rpc server programme. 100007 1 tcp 38903 c++rpc 100007 2 tcp 60872 c++rpc

  1. 3 tcp 60987 c++rpc Please give me your suggestion regarding this . svc = new OncRpcSvcBuilder() .withoutAutoPublish() .withTCP() .withMinPort(1) .withMaxport(60000) .withWorkerThreadIoStrategy() .withBindAddress("127.0.0.1") .withSelectorThreadPoolSize(1) .withWorkerThreadPoolSize(1) .withRpcService(new OncRpcProgram(PROGNUM, PROGVER), echo) .withServiceName("c++rpc") .build(); svc.start() Here Program version(1to 32),IP address(1 to 4) I need to pass it differently??. And I want to do the same the process on different address like ip address1, ip address2 ,ip address3, ip address 4.. is it possible . I tried with above code and changed the bind address.what is the use of withbindaddress()? but it is throwing bind exception ..am run it on Windows but I pass the parameters in withbindaddress(Linux machine ip adderess1). I checked etc/hosts in Linux .I gave the localhost address from that file .still it is throwing bind exception. But when I gave the local address of Windows .it is registering the portmapper in Windows .please give me your suggestions regarding this
