Reading .pb file

[Vijay Miriyala]

I am new to ProtoBuff file formats. I received a zip file which contains .pb file. I do not have .proto file. Is there a way to read the contents of the .pbp file in Java using the libraries?

Thank you

You need a .proto file to parse protobuf messages because otherwise you won't be able to know what's in the data file.

You can use protoc --decode_raw to decode it. It will give you a
probable decoding of the message -- some specifics can't be known from
the encoding alone (e.g. string vs submessage, various types of ints,
etc are confusable).

You could implement this same functionality using the libraries
(protoc does it, so there must be a way!) but... it seems like it'd be
easier to create a proto file based on the sample for you to use and
work with that.
