JSR 265 aims to standardize an API for utilizing Web services constraints and capabilities. Constraints and capabilities refer to web services metadata, such as Quality Of Service (QoS). It will provide interfaces to obtain and access the capabilities in effect for any given message exchange instance. This API will enable other Java technologies to utilize constraints and capabilities in a uniform manner thereby strengthening Java as a competitive Web services platform.
We expect that JSR 265 will be utilized from within other Java specifications for Web services, such as JAX-WSA (JSR 261), JAX-RPC (JSR 224), and JBI (JSR 208).
We are excited to be taking on this specification!
