[protobuf] Re: Using Protocol Buffer in other Languages
Hi. You can write your own parser, the structure to follow it is not difficult. You can download the source code for protobuffer and you will have the compiler/cpp, compiler/java and compiler/python parsers to copy. I wrote the first version of parser to generate code for fitnesse in two days. El jueves, 30 de agosto de 2012 16:13:54 UTC+2, Atanu escribió: Hi all, I am very new to this technology. After going through the blogs and materials I find it to be interesting. I am an SAP ABAP developer. If I want to use this in my technology, is there any suitable parser? If not then what can be the solution ? DO I need to define my own parser? Can anybody help me on this.

[protobuf] streaming multiple messages to 1 stream
I've read the suggestion about first writing the size of each message followed by the message in order to workaround the issue that protocol buffer parsers don't know where 1 message ends and another begins. Could someone show example code on how to do this for a C# client sending a message to a C++ server. That would be most appreciated. -- You received this message because you are subscribed to the Google Groups Protocol Buffers group.

[protobuf] Job.proto:11:18: DescriptorProto is not defined.
Hi,
I am trying to compile my .proto file using protoc compiler and generate
java classes for the same.
Below is my Job.proto file
*import google/protobuf/descriptor.proto;
option java_package = com.myfile.test;
option java_outer_classname = JobProto;
message Job{
required string companyName = 1;
required string designation = 2;
required int32 salary = 3;
required DescriptorProto file_prot = 4;
}*
And my protoc command is
*protoc %Input%\Job.proto --java_out=%Output% --descriptor_set_out=job.desc
--proto_path=%Input% --proto_path=%protobuf_src_folder%*
where environment variable definition are:
Input: Folder in which Job.proto file is present
Output: Foldedr where my output classes are generated
protobuf_src_folder: Path till ..\protobuf-2.4.1\src
when i execute the above command i get
*Job.proto:11:18: DescriptorProto is not defined.*
I have tried copying the discriptor.proto in the same folder and modifying
the import statement (still i get the same error). Whatever i have browse i
just found setting --proto_path properly but in my case the path is proper
but still i am getting the same error. I have also ensure that my protobuf
source version and protoc version are same 2.4.1
Can anyone tell me whats wrong ?

[protobuf] ignoring part of the message -?
Hi, My message is an UDP packet header and I have to ignore the rest of the packet. How can I express that in .proto syntax? Note that the header length is fixed (70B), but the packet length is not Also, would it be possible to validate that those first 70B really conform to the message specification in .proto?

Re: [protobuf] Job.proto:11:18: DescriptorProto is not defined.
To start with you need to use the qualify with the package as
google.protobuf.DescriptorProto. See the section on Name Resolution:
https://developers.google.com/protocol-buffers/docs/proto#packages
Assuming your paths are set up correctly it should work after that.
