| [wtp-dev] WTP 2.0 - JSF Tools Project: Support for Unified Expression Language.. |
|
Hi, The JSF Tools project is targeting support for JavaServer
Faces 1.2 (Java 5 EE) in the WTP 2.0 release. As a first step, we have identified
the requirements for supporting the Unified _expression_ Language and have posted
a document on the JSF Tools Project Wiki, http://wiki.eclipse.org/index.php/Unified_Expression_Language_Support Please review and post your comments to the
development mailing list, wtp-jsf-dev@xxxxxxxxxxx
. Thanks Raghu Srinivasan Project Lead – JSF Tools Project Summary: The JavaEE 5.0 specification defines a new "Unified
_expression_ Language" that is to be used by both release 1.2 of Java Server
Faces (JSF) and release 2.1 of Java Server Pages (JSP). The new EL language is
intended to be completely independent of its container (i.e. JSP). A new Java
API and _expression_ evaluation mechanism has been defined to support this
container independence. The new evaluation mechanism, although mostly backward
compatible, has a significant impact on the way tooling supports design time
_expression_ evaluation for the purposes of such features as validation and
auto-completion. This document enumerates the changes to EL as they affect
the JSP/JSF tooling and discusses framework changes that will be required to
support Unified EL for Faces 1.2. Previous limitations of the framework and
backward compatibility are also considered. |
