I am using **protobuf** now for some weeks, but I still keep getting exceptions when parsing protobuf messages in **Java**.
I use **C++** to create my protobuf messages and send them with **boost sockets** to a server socket where the Java client ist listening. The C++ code for transmitting the message is this: boost::asio::streambuf b; std::ostream os(&b); ZeroCopyOutputStream *raw_output = new OstreamOutputStream(&os); CodedOutputStream *coded_output = new CodedOutputStream(raw_output); coded_output->WriteVarint32(agentMessage.ByteSize()); agentMessage.SerializeToCodedStream(coded_output); delete coded_output; delete raw_output; boost::system::error_code ignored_error; boost::asio::async_write(socket, b.data(), boost::bind( &MessageService::handle_write, this, boost::asio::placeholders::error)); As you can see I write with `WriteVarint32` the length of the message, thus the Java side should know by using `parseDelimitedFrom` how far it should read: AgentMessage agentMessage = AgentMessageProtos.AgentMessage .parseDelimitedFrom(socket.getInputStream()); But it's no help, I keep getting these kind of Exceptions: Protocol message contained an invalid tag (zero). Message missing required fields: ... It is **important** to know, that these exceptions are not thrown on every message. This is only a fraction of the messages I receive the most work out just fine - still I would like to fix this since I do not want to omit the messages. I would be really gratful if someone could help me out or spent his ideas. -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
