I've got a java server and a c++ client, client sends a message to the
server.
In a first moment we had the message structure made by simple format
like strings or integers, and the message sending/receiving with
serialization and deserialization were working perfectly.
Nowadays we added a "enum" in the structure and now on the java side,
the deserialization doesn't work anymore:
c++ client sending:
bool Client::SendMsg(const char* pStr)
{
if (send(m_iSock, (char *) pStr, strlen(pStr), 0) == -1) //
send(id_socket,stringa,lunghezza stringa,flags)
{
perror("Client::SendString, send");
return false;
}
return true
}
//on the client'smain
ss=(const char*)malloc(1000);
ss = obj.c_str();
mylink.SendMsg(ss);
java server receiving:
public int ReceiveMsg() throws IOException
{
InputStream InMsg = sock.getInputStream();
ProtoMessage Msg = ProtoMessage.parseFrom(InMsg); //THIS
THROWS THE ERROR
sock.close;
}
the error is:
Exception in thread "main"
com.google.protobuf.InvalidProtocolBufferException: While parsing a
protocol message, the input ended unexpectedly in the middle of a
field. This could mean either than the input has been truncated or
that an embedded message misreported its own length.

On the other side otherwise c++ client can deserialize the stream
perfectly.
I'm gettin mad, without the enum the send/receive is working!
any ideas?
thanks in advance
Enrico
