Running a sample AddPerson.java example - Fails giving "Protocol message tag had invalid wire type"

[Dhaval Kotecha]

Hi All,

I am a newbie to Protocol Buffers. I am trying to run the AddPerson example, and it fails giving me the error as mentioned below with the whole stacktrace.

Exception in thread "main" com.google.protobuf.InvalidProtocolBufferException: Protocol message tag had invalid wire type.

I am giving the "\protobuf-2.5.0\examples\addressbook.proto" as an argument for ADDRESS_BOOK_FILE.

What am I missing out here?

Thanks,

Dhaval

I think it wants a file with proto data, not the proto description.
Also it wants it proto-encoded, not text-encoded.
