You attempt to create a registry first. That will always fail on the second and
subsequent attempts because there is already another registry running on that
port.

You should attempt locate a registry first, and if that fails because there is
none, then create one.

but it doesnt work,i got exception
that smth is already using the port and i cant connect...

Your error messages are not in English, so I've no idea what exception you are
actually throwing. You also catch the blanket Exception and don't ever report
what the actual Exception is, or the message it returns, so how can you say
that it reports that something is already using the port? That may be what
*you* are writing to System.out, but it may not bear any relation to the actual
situation. What you need to do is output the actual Exception message and see
what's really going on.

it was
working before,right now no :( so i used 3 ports to every
application :/

       if (System.getSecurityManager() == null)
               System.setSecurityManager(
          new java.rmi.RMISecurityManager());

       java.rmi.registry.Registry reg = null;
       try {
       reg = java.rmi.registry.LocateRegistry.createRegistry(1099);
       System.out.println("Utworzone nowe registry na porcie 1099.");
       } catch (Exception e) {
               System.out.println("Nie powiodlo sie utworzenie registry.");
               System.out.println("Skorzystam z istniejacego.");
       }
       if (reg == null) {
               try {
               reg = java.rmi.registry.LocateRegistry.getRegistry();
               System.out.println("Skorzystalam z zarejestrowanego registry");
               } catch (Exception e) {
        System.out.println("Nie moge skorzystac z istniejacego
registry.");
        System.exit(0);
               }
       }
       try {
               serwer obj = new serwer();
       reg.rebind("pomiar", obj);
      System.out.println("Usuga zarejestrowana.");
       }
       catch (Exception e) {
       e.printStackTrace();
       }
