Please, help in RMI UnmarshalException: nested exception is: EOFException

Question

Good day,
I have a problem in sample program, similar like an Oracle oriinal in "Getting Started Usin Java RMI", identically on server and client sides. It correctly works in NetBeans IDE, but never alone, as JAR archive or java class, if I used java -jar or java -classpath command-line form. Fragment of the server code includes final check on correct read from remote object, it corrrectly works within NetBeans but cause UnmarshalException in same server side in independent launch form (WeatherBean - sample object, contains points to information about city name, weather description, temperathure an small "weather" icon, WeatherService - interface with one getWeatherInformation() function):
               String serverObjectName = "WeatherService";
               final int remotePort = 1099;
               final String remoteHost = "localhost";
               Registry registry = LocateRegistry.getRegistry(remoteHost);
               WeatherService remoteObject = (WeatherService)
                       UnicastRemoteObject.exportObject(service, 0);
               registry.rebind(serverObjectName, remoteObject);
               //control export output
               java.util.List<WeatherBean> list =
                       service.getWeatherInformation();
               for (int i = 0; i < list.size(); i++) {
                   WeatherBean wb = list.get(i);
                   service.addTextWeatherString(wb.getCityName() + " " +
                           wb.getDescription() + " " + wb.getTemperature());
               //back read exported object (cause error)
               String[] regArr = registry.list();
               java.util.List<String> regList = Arrays.asList(regArr);
               if (regList.contains(serverObjectName)) {
                    Remote remote = registry.lookup(serverObjectName);
                    if (Proxy.isProxyClass(remote.getClass())) {
                        Proxy proxy = (Proxy) remote;
                        InvocationHandler invocationHandler =
                                Proxy.getInvocationHandler(proxy);
                        WeatherService weatherService = (WeatherService)
                                Proxy.newProxyInstance(
                                WeatherService.class.getClassLoader(),
                                new Class[] { WeatherService.class },
                                              invocationHandler);
                        list = weatherService.getWeatherInformation();
                        for (int i = 0; i < list.size(); i++) {
                        WeatherBean wb = list.get(i);
                        service.addTextWeatherString(wb.getCityName() + " " +
                                wb.getDescription() + " " + wb.getTemperature());
               }Starts with form java -jar WeatherServiceProj.jar (my project name) cause this error:

Great thanks for some little help,
Jaroslav

Answer 1

Sweta,
Is this a java mapping or Graphical, If Java, you should not run into this issue as you dont load the nested XSD`s.
Also the error message indicates outofMemory in mercator side when posting your Large message.
java.lang.OutOfMemoryError at com.philips.xi.mercator.MercatorCall.execute(MercatorCall.java:90) at
