Java Pojo Classes -> ASN.1 for RPC

Question

I would like to do some RPC with the format of the messages being directly defined from Java interfaces, then I want to use some tools to generate the ASN.1 files.

1. Do you know what tools I can use? (if possible, something that doesn't force me to use any type from an ASN library in the interfaces which describe the format.

2. Do you know if there are libraries to do RPC with ASN.1 in a JavaSE program?

Answer 1

I guess that annotating the classes and writing annotation processor producing ASN could be a way but I can't guess amount of work it will take.
