rmi - java.lang.IllegalArgumentException: argument type mismatch $Proxy0.joinNetwork(Unknown Source) -


here code:

public class peernode extends unicastremoteobject implements peerinterface {      private peerinterface joint;     private list<peernode> neighbours;     public peernode(string s, int idnumber) throws ioexception {         peernode.setnome(s);         peernode.setkey(idnumber);         this.neighbours = new arraylist<>();         system.out.println("peer node initialized");         system.out.println(this);     }      public void contactexistingnode(string node) throws exception, remoteexception, notboundexception {         system.out.println("i know peer "+ node);         system.out.println("i try join automatically network");         joint = (peerinterface) registry.lookup(node);         joint.joinnetwork(this);     }

and interface:

public interface peerinterface extends remote {      public void joinnetwork(peernode p) throws remoteexception;  }

i'm trying pass object remote peer... , @ line

joint.joinnetwork(this);

i have error:

exception in thread "main" java.lang.illegalargumentexception: argument type mismatch ... @ com.sun.proxy.$proxy0.joinnetwork(unknown source) @ com.server.peernode.contactexistingnode(peernode.java:41) @ com.server.main.main(main.java:51)

i casted peerinterface, peernode... doesn't work. can me? class receive object

public void joinnetwork(peernode p) throws remoteexception {     neighbours.add(p); }

the client doesn't have instance of remote object. has instance of remote interface. signature of remote method should be

void joinnetwork(peerinterface peer) throws remoteexception;

fix remote interface, remote object, , client; region; redeploy; , retest.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
