Jakarta Servlet

This feature enables support for HTTP Servlets written to the Jakarta Servlet 5.0 specification. You can package servlets in Jakarta EE specified WAR or EAR files. If servlet security is required, you should also configure an appSecurity feature. Without a security feature, any security constraints for the application are ignored.

If you are updating your application from using the servlet-5.0 feature to using the servlet-6.0 feature, changes in API behavior might require you to update your application code. For more information, see Differences between Jakarta Servlet 6.0 and 5.0.
