JSTL 1.2 core library

The pre JSF 2.0 version of Facelets incorrectly declared the taglib uri to be http://java.sun.com/jstl/core. For backwards compatibility implementations must correctly handle inclusions with the incorrect uri, and the correct uri, declared here.

Tag Summary
catchCatches any Throwable that occurs in its body and optionally exposes it.
chooseSimple conditional tag that establishes a context for mutually exclusive conditional operations, marked by and
ifSimple conditional tag, which evalutes its body if the supplied condition is true and optionally exposes a Boolean scripting variable representing the evaluation of this condition
forEachThe basic iteration tag, accepting many different collection types and supporting subsetting and other functionality
otherwiseSubtag of that follows tags and runs only if all of the prior conditions evaluated to 'false'

Sets the result of an expression evaluation based on the value of the attributes. If "scope" the is present, but has a zero length or is equal to the string "page", TagException is thrown with an informative error message, ensuring page location information is saved.

This handler operates in one of two ways.

  1. The user has set "var", "value" and (optionally) "scope" attributes.

  2. The user has set "target", "property", and "value" attributes.

The first case takes precedence over the second.

whenSubtag of that includes its body if its condition evalutes to 'true'
