[protobuf] Zero tag number in enum data type
hello, i just wanna share. In Protobuf developer guide, in the sample proto file, there is a PhoneType enum data type, consist of MOBILE, HOME, and WORK. MOBILE use '0' as its tag number, and so on. Meanwhile, i'm using Protobuf plugin for Netbeans, for my project. When i was try to compile a proto file, there was an error. The error was in enum data type. Compiler couldn't compile enum data that had '0' tag number. Then, when I change to '1', it can run successfully. Any explanations?

[protobuf] Re: Zero tag number in enum data type
Sorry, my mistakes :)
But, when I try to give 0 as the enum value, compiler can't compile
it. Is it a bug from the compiler? (I use protobuf plugin in
neatbeans)

You mean this?
enum PhoneType {
MOBILE = 0;
HOME = 1;
WORK = 2;
}
message PhoneNumber {
required string number = 1;
optional PhoneType type = 2 [default = HOME];
}
The zero is not a tag / field-number; it is just an enum value. The 2 on the
last line I've copied is a tag relating to a *use* of that enum.

[protobuf] Re: Protobuf in JAX-WS
Or, maybe can I handle request and read the callback without using JAX WS (without java.xml.ws library)?

[protobuf] Re: Protobuf in JAX-WS
thanks. Actually, i'm using Restful web services. But, i'm confuse, how to use it for long polling method. I have search it, but the result is using JAX WS to handle the request and get callback response. is there a way to do it in pure protobuf? Maybe using another library?
