- public class ScriptFreeTLV
- extends TagLibraryValidator
A SAX-based TagLibraryValidator for enforcing restrictions against
the use of JSP scripting elements.
This TLV supports four initialization parameters, for controlling
which of the four types of scripting elements are allowed or prohibited:
- allowDeclarations: if true, indicates that declaration elements
are not prohibited.
- allowScriptlets: if true, indicates that scriptlets are not
prohibited
- allowExpressions: if true, indicates that top-level expression
elements (i.e., expressions not associated with request-time attribute
values) are not prohibited.
- allowRTExpressions: if true, indicates that expression elements
associated with request-time attribute values are not prohibited.
The default value for all for initialization parameters is false,
indicating all forms of scripting elements are to be prohibited.
