[protobuf] Using protobuf to exchange messages between c++ and java
Hello all,
I'm trying to exchange messages between c++ and java and vice-versa without
success.
I've defined two messages (1 to be sent from c++ to java and another to be
sent the other way around) with union types (see attached .proto).
The c++ code is as follows:
*operational_gui::OperationalMessage message;
message.set_type(operational_gui::OperationalMessage::OWNPOSITIONREPORT);
message.mutable_oprep()-set_latitude(38.5);
message.mutable_oprep()-set_longitude(-9.8);
message.mutable_oprep()-set_heading(25);
message.mutable_oprep()-set_validity(0);
message.SerializeToArray(buf, message.ByteSize());
m_pNamedPipeSocket-write(buf, message.ByteSize());
m_pNamedPipeSocket-flush();*
The java code is as follows:
*int bytes = pipe.read(buffer);
MessagesProtos.OperationalMessage message =
MessagesProtos.OperationalMessage.parseFrom(buffer);
switch(message.getType()){
case OWNPOSITIONREPORT:
System.out.println(Response is OwnPositionReport);
break;
case FRIENDPOSITIONREPORT:
System.out.println(Response is FriendPositionReport);
break;
case COMMSTATUSREPORT:
System.out.println(Response is CommStatusReport);
break;
}*
**
The communication is made by pipes (QLocalSocket on c++, FileInputStream on
java side)
C++ sends 33 bytes and java received them all but blows with an exception
*InvalidProtocolBufferException:
Protocol message contained an invalid tag (zero).*
Any hints ?
Thanks in advance.

Use bytes here, not chars. In fact this code shouldn’t even compile; java.io.FileInputStream doesn’t *have* a read() method that takes a char array!
