Jakarta Server Pages

This feature enables support for Jakarta Server Pages that are written to the Jakarta Server Pages 3.1 specification. This framework simplifies the construction of user interfaces. Enabling this feature also enables the Jakarta Expression Language version 5.0 feature.

If you are updating your application from using the pages-3.0 feature to using the pages-3.1 feature, changes in API behavior might require you to update your application code. For more information, see Differences between Jakarta Server Pages 3.0 and 3.1.
