JavaServer Pages 2.3 feature functions

The JavaServer Pages (JSP) 2.3 feature provides full support for the JSP 2.3 specification.

Descriptions of the new JSP 2.3 functions are provided in the JSP 2.3 specification and are not described here. However, the new specification additions are minor, as compared to the JSP 2.2 feature:

• Support for Expression Language (EL) 3.0
• Availability of Servlet 3.1 APIs to a JSP. See Servlet 3.1 support to determine which new APIs are available.

• There are no known behavior differences between JSP 2.2 and JSP 2.3 that directly prevent a JSP that runs with JSP 2.2 from successfully running with JSP 2.3. However, if a JSP uses Expression Language (EL) or Servlet API functions, consider the changes between Servlet 3.1 and Servlet 3.0, and between EL 3.0 and EL 2.2.
