Jakarta Server Pages 3.1

Jakarta Server Pages defines a template engine for web applications that supports mixing of textual content (including HTML and XML) with custom tags, expression language, and embedded Java code, that gets compiled into a Jakarta Servlet.

New features, enhancements or additions

  • 40 Add an option to raise a PropertyNotFoundException when an EL expression contains an unknown identifier
  • 42 Clarify the meaning of ‘scope’ in the context of scripting variables associated with custom actions
  • 44 Clarify that the EL environment within a JSP has a set of default imports consistent with the default imports for the scripting environment. Refactor the ScopedAttributeELResolver to remove the special handling for imports and unresolved variables

Removals, deprecations or backwards incompatible changes

  • Deprecate methods that override ELResolver.getFeatureDescriptors() as that method has been deprecated as of EL 5.0
  • Deprecate the isThreadSafe page directive attribute as the related Servlet API interface SingleThreadModel has been removed as of the Servlet 6.0 specification
  • 226 Deprecate the jsp:plugin action and related actions as the associated HTML elements are no longer supported by any major borowser
