The JCP has been active of late, issuing many public drafts of various relevant specifications, including the Servlet 3.0
draft, the JavaServer Faces 2.0
draft, the Java Connector Architecture 1.6
draft, and the Service Data Objects
Each JSR is significant in its own way.
The Servlet 3.0 JSR focuses on web framework pluggability, annotation support, async and Comet support (which has caused some discussion here on TSS and in the JSR itself!), security, alignment with the REST JSR, and other clarifications, such as file upload progress listeners and some threadsafe clarifications.
The Java Connector Architecture adds some classloader changes, distributed work processing, bean validation, and other fairly minor changes (although it's certain that the expert group will dispute the description as "minor.")
The Service Data Objects draft has been in progress since 2003, and is a mechanism to "pass data between a business tier and a persistence tier. The persistence tier is responsible for encapsulating the access to whatever persistent data storage mechanism is being used. The Service Data Object represents the data in a way that is independent of the underlying persistence technology," from the JSR page
