About JavaServer Faces
Task applications created in the Designer Task Development support the JavaServer Faces (JSF) standard. Task applications created with version 9.6 and earlier were implemented with JSF 1.x support. Beginning with version 9.7, JSF 2.x is supported, enabling you to develop facelet applications.
Support of facelets provides you with the ability to use:
XHTML to create web pages.
Facelets tag libraries to augment JavaServer Faces and JSTL tag libraries.
The Java Unified Expression Language (UEL).
Templates for components and pages.
Beginning with version 9.7, you can create new task projects in either of two ways:
As JSF 1.x applications that use View Declaration Language (VDL) files implemented as .view files. These projects will behave exactly like those developed in earlier projects. You can convert them to JSF 2.x facelet applications with VDL files implemented as .xhtml files.
As JSF 2.x applications that support the use of.xhtml view files. In this case, when you add a new portlet or and individual view file, the new view file is added in JSF 1.x format, and you must migrate it to JSF 2.x format.
Task applications developed with JSF 1.x in earlier versions can be migrated into JSF 2.x facelet applications at the project level. Individual .view files can also be migrated to .xhtml files.
For more information about working with facelets, see webMethods CAF and OpenUI Development Help.
