[protobuf] Error with Netty and extensions
Hi all
i am trying to use extensions with protobuf and Netty
here's my proto file
package tutorial;
option java_package = com.example.messages;
option java_outer_classname = MessageProtos;
option optimize_for = LITE_RUNTIME;
enum MessageType {
TEST = 0;
DEBUG = 1;
DO_TASK = 2;
SPECIAL = 3;
}
message Message {
required string content = 1;
required MessageType type = 2;
extensions 3 to 99;
}
extend Message {
optional string enhancedContent = 3;
optional Share share = 4;
optional int32 bar = 5;
}
message Share {
required string ticker = 10;
required string company = 11;
required double price = 12;
}
I am setting extensions this way in my client
if(line.startsWith(task)) {
builder.setType(MessageProtos.MessageType.DO_TASK);
builder.setExtension(MessageProtos.bar, 1);
} else {
builder.setType(MessageProtos.MessageType.DEBUG);
}
I have written an unit test which works fine
@Test
public void testExtensions() throws Exception {
MessageProtos.Message.Builder builder =
MessageProtos.Message.newBuilder();
builder.setExtension(MessageProtos.bar, 1);
builder.setContent(foobar);
builder.setType(MessageProtos.MessageType.DEBUG);
MessageProtos.Message message = builder.build();
Assert.assertTrue(message.hasExtension(MessageProtos.bar));
}
However, on the serverside i am getting this exception
2011-02-06 20:44:58,130 [handlers.EchoServerHandler ]

Do i need to somehow declare extensions whenever i register my
ProtocolDecoder / ProtocolEncoder?
If i don't set any extensions, the client-server communication works
fine
could anyone help?

[protobuf] Re: why am i getting this exception?
Hello,
PLs ignore my message
It was a Netty problem as i was using multiple decoders / encoders /
frames and that was messing up the result
sorry for bothering

[protobuf] protocol buffers and client-server communication
Hi all i am new to protocol buffer, and was wondering if i can use it for my needs. Basically, i am trying to implement a client-server communication where i can have this type of messages: - INCOMING (from client to server) - String - a Savings Object - a Share object - OUTCOMING (from server to client) - String - a List of Savings objects - a List of Share object Basically, what i am trying to say is that i have N types of messages from client to server and M types of messages from server to client, and all this messages are differents from each other (having in total N + M) types of messages. I am guessing i will need 1 proto file for each type of message, correct? w/kindest regards marco -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.
