Simple 'read' question

[MohanR]

Hi,
The following simple example throws an exception when I 'read'
which I think is caused by my bad code. What is missing here ?

Thanks.

InvalidProtocolBufferExceptionProtocol message contained an invalid
tag (zero).
com.google.protobuf.InvalidProtocolBufferException: Protocol message
contained an invalid tag (zero).
at
com.google.protobuf.InvalidProtocolBufferException.invalidTag(InvalidProtocolBufferException.java:
68)

108)

------------------------------------------------------------

package message;

message Load {

enum LoadType {
HIGH = 0;
MEDIUM = 1;
LOW = 2;
}
message LoadBalance {
optional LoadType type = 2 [default = MEDIUM];
}
optional LoadBalance loadbalancer = 1;
}

------------------------------------------------------------
Write------------------------------------------------------------


Message.Load message =
Message.Load.newBuilder().setLoadbalancer(

Message.Load.LoadBalance.newBuilder().setType( Message.Load.LoadType.HIGH)).build();
System.out.println( "Distributed value is " +
message.getAllFields() );
return message.toByteArray(); // write somewhere

Message.Load message = Message.Load.parseFrom( value );
