More Java EE 7 content: Servlet, EL, JMS and JSF updates

Following-up on to yesterday's post on JSR 342 (Java EE 7), there are actually four other JSRs that have been filed :
JSR 340: Java Servlet 3.1 Specification
JSR 341: Expression Language 3.0
JSR 343: JavaTM Message Service 2.0
JSR 344: JavaServerTM Faces 2.2

JCP - Java Community Process

Servlet 3.1 should offer easier to build asynchronous applications (extending the work done for 3.0), support and utilize Java EE concurrency APIs, support WebSockets, offer multi-tenant isolation support and more. The co-spec leads are Shing Wai Chan and Rajiv Mordani.

Expression Language (EL) 3.0, which used to be defined as part of the JSP expert group, now has a dedicated JSR due to its relationship with other parts of the platform such as CDI and JSF. The goal there is to consider support for projection and collection, date types (with appropriate comparison operators) and maybe equality, string concatenation, and sizeof operators. Kin-man Chung is the specification lead.

JMS 2.0 should bring to this API some long awaited EoD (Ease of Development) love, clarification of the relationship between the JMS and other Java EE specifications and a new mandatory API for the integration of any JMS provider in Java EE application servers. Nigel Deakin is the spec lead for this one.

JavaServer Faces (JSF) 2.2 will continue to focus on ease of development, better portlet integration but also consider new features (HTML 5 and others), and of course work on fixes. The plan is to finish before the end of this calendar year (2011). Check out Ed Burns' recent post on this.

All JSRs are now up for voting and slatted for inclusion in Java EE 7, thus hopefully joining JPA 2.1 and JAX-RS 2.0 in the list of "work in progress" JSRs. Speaking of JAX-RS, Marek, the new co-spec lead has a quick update.
