# Java™ Servlet

# Technology Compatibility Kit, Version 4.0
Release Notes, August 2017

## Kit Contents

The Java™ Servlet, Version 4.0 Technology Compatibility Kit (Servlet TCK) includes the following items:

- Servlet TCK Signature, API, and End-to-end tests:

  - A Signature test that checks that all of the public APIs are supported or defined as specified in the Servlet Version 4.0 implementation that is being tested.

  - API tests for all of the public APIs and language elements defined by the Servlet 4.0 Specification.

  - End-to-end tests for sending http requests to the web container or server and receiving responses based on the Servlet 4.0 Specification.

## Platform Notes

- The Servlet TCK tests have been built and tested with the Java™ Platform, Standard Edition SDK, Version 1.8 and Java™ Platform, Enterprise Edition reference implementation, Version 8 (Java EE 8 RI).

- In the instructions in this document, variables in angle brackets need to be expanded for each platform. For example, `<TS_HOME>` becomes `$TS_HOME` on Solaris/Linux and `%TS_HOME%` on Windows. In addition, the forward slashes (`/`) used in all of the examples need to be replaced with backslashes (`\`) for Windows.
