Hi all, Emmanuel and I have been discussing the integration of BV and JAX-RS (RESTful web services) with the JAX-RS 2.0 EG. The basic idea is to place constraint annotations on JAX-RS resource types and perform a validation of the same at defined times in the request life cycle. In particular, JAX-RS makes use of the new method validation API to validate parameters and return values of resource methods. The JAX-RS 2.0 EG recently published their third early draft for public review [1], so in case you're interested, you might have a look at the spec (chapter 7 describes the BV integration) and provide your feedback. I think simplest is if you post any comments to both EGs (the JAX-RS mailing lists can be found at [2]). Thanks, --Gunnar [1] http://jcp.org/en/jsr/detail?id=339 [2] http://java.net/projects/jax-rs-spec/lists
