Section 2: Request
This JSR requests the creation of the next versions of the Java Servlet and JavaServer Pages specifications. The version numbers tentatively assigned are Servlet 2.3 and JSP 1.2. These two specifications will be part of the Java 2 Enterprise Edition platform.
Since the JavaServer Pages specifications are tightly defined on top
of the Java Servlet specifications, we plan to define both
specifications in parallel to eliminate discrepancies and confusion,
and to reduce development cost. We plan to structure the
documentation so that the Java Servlet specification can be used
independently of the JavaServer Pages specification,
2.1 Target Java platform
The Servlet 2.2 and JSP 1.1 specifications are part of the Java 2
Enterprise Edition, version 1.2 (J2EE 1.2) platform.
We expect that this proposed specifications will be part of the next
release of the J2EE Platform.
As with the current versions of the specification,
we expect the new versions to be usable on the J2SE platform.
2.2 Need of the Java Community that this work addresses
The new Servlet and JSP specifications will add some functionality that was already known to be missing from the current specifications and that was not incorporated due to time constraints or because additional research was needed before determining the correct approach.
In addition, the new Servlet and JSP specifications will incorporate new functionality requested by our parterns and the public, reflecting, in some cases, their quickly evolving needs.
The requirement areas we intend to address include, but are not limited to, the following:
In some cases the same solution may address multiple requirements. Also, in some cases, the best response to the requirement may be outside of the specification.
As discussed above, these areas are largely unspecified in Servlet 2.2
and JSP 1.1. Consequently, Web Application authors, server vendors and
tool vendors must either ignore these areas or offer support using
vendor-specific architectures.
2.4 Specification to be developed and how it addresses the need
We request the development of a new version of the Servlet specification
and a companion new version of the JavaServer Pages specification.
2.5 Detailed description of the underlying technology or technologies
A detailed description of Servlet 2.2 and JSP 1.1 functionality can
be found in the respective specification documents, which can be downloaded
from the sites at http://java.sun.com/product/servlet/download.html and
http://java.sun.com/product/jsp/download.html.
2.6 Proposed package name for API Specification
We expect to use the existing packages used by the Servlet 2.2
and JSP 1.1 specifications: javax.servlet, javax.servlet.jsp,
and javax.servlet.jsp.tagext.
2.7 Security implications
Security mechanisms must be compatible with the security facilities of J2SE 1.3.
2.8 Internationalization implications
Improved internationalization and locatization capabilities for JSP and
Servlets is one of the key goals of this JSR, as noted above.
2.9 Localization implications
See 2.8.
2.10 Risk assessment (impact of work on target platform, impact if work
not carried out, difficulties in carrying out RI and/or CTS)
In the absence of these new specifications, it is highly likely that Web containers providers will develop container-specific mechanisms to support the facilities listed in section 2.2 of this document. If this occurs it will limit the portability of Servlet and JSP applications and tools.
An analysis of partner needs must be done to determine whether it is possible
to target the new specifications exclusively to the Java 2 platform,
or if the earlier versions of the specification still need to be considered.
2.11 Existing specifications that might be rendered obsolete or
deprecated by this work
A primary goal is backward compatibility.
All applications that use the Servlet 2.2 and JSP 1.2 specifications
must be compatible with Servlet 2.3 and JSP 1.2 specifications.
2.12 Existing specifications that might need revisions as a result of
this work
See 2.11 above.

JSR-052, "A Standard Tag Library for JavaServer Pages" (in preparation)
http://www.jcp.org/jsr/detail/52.jsp
3.2 Explanation of how these items might be used as a starting point for
the work
These Servlet 2.3 and JSP 1.2 specifications will be based on the current Servlet 2.2 and JSP 1.1 specifications. The Application Programming Model work will be used to ground the new designs. The J2EE documents provide context for the use of Servlets and JSP within the J2EE platform.
We expect to take advantage of the experience gained from a number of projects, including several that are represented in the endorsement list.
JSR-052, "A Standard Tag Library for JavaServer Pages" requests the creation of a standard JSP tag library; that specification effort will have a symbiotic relationship with this one. Similarly, we expect to take advantage of JSR-045 "Debugging Support for Other Languages" to provide improved debugging support for JSP. Finally, we expect to start getting some feedback from and input into JSR-039, "Java Servlet and JavaServer Pages Performance".
