I'm after the same thing. I suggest you take a look at protostuff: http://code.google.com/p/protostuff/ I only just discovered it myself a few days ago and seems to do what you want (actually it converts to/from POJO to protobuf byte[]). It also appears to be very efficient - often faster than protocol buffers itself: http://code.google.com/p/thrift-protobuf-compare/wiki/BenchmarkingV2 There are a few caveats but on the whole it looks rather promising. The conversion process is straightforward: // Generate a schema based on your Pojo Schema<Pojo> schema = RuntimeSchema.createFrom(Pojo.class); // Convert the Pojo to a byte[] Pojo p = ... LinkedBuffer buf = LinkedBuffer.allocate(500); byte[] data = ProtobufIOUtil.toByteArray(p, schema, buf); // Populate a Pojo based on a byte[] and schema Pojo p2 = new Pojo(); ProtobufIOUtil.mergeFrom(data, p2, schema); -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
