New to Jakarta Servlet

Jakarta EE is the continuation of the Java EE (J2EE) specification. It focuses on distributed computing and web services.

ZK framework in Java EE and Jakarta EE specification sets

ZK Framework is based on the servlet specification, which is part of both Java EE and Jakarta EE specifications.

From a ZK developer point of view, the differences between the two are minor. Different version of the servlet specification will provide different features.

Which ZK version should I choose?

Starting from ZK 9.6.0, you will be able to choose from two Framework versions:

This version supports Java EE servlet 2.4 and higher. It is compatible with Java EE based Web Servers implementing this specification.

Which servlet version does my webserver support?

This depends on your webserver. We recommend that you check the servlet support directly in your webserver's documentation.
