Issue with Protobuf and Thrift content type


 

Hi,

                

In my Java application,I want to provide support for Avro, Thrift and
Protobuf. I am using java classes generated by avro schema and  avro idl.
When I use ProtoBufDatumReader and ProtoBufDatumWriter classes to support
encode and decode Protobuf content. I get following exception:

java.lang.RuntimeException: java.lang.NoSuchMethodException:
org.openrtb.common.api.BidRequest.getDescriptor()

      at
org.apache.avro.protobuf.ProtobufData.getSchema(ProtobufData.java:181)

      at

Similarly Thrift content type is also not working for me. Following is the
exception:
