Release Note

WhisperCoaching — Release Notes

Version 2.3 (May 2026)

Overview

Major modernization release. Upgraded from Java 8 / Jersey 2.x / javax.* to Java 21 / Jersey 3.1 / Jakarta EE 10. No functional changes to whisper coaching behaviour.

Compatibility

Component

Version

Java (minimum)

Apache Tomcat

9.x and below ❌ Incompatible (javax.* namespace)

Cisco JTAPI

10.0

Cisco CUCM

Compatible with JTAPI 10.0 supported releases

Note: Tomcat 10.1 is required because it implements Jakarta EE 10 (jakarta.* namespace). Tomcat 9.x and earlier use the old javax.* namespace and are not compatible with this build.

What Changed

Java Runtime

  • Now: Java 21 (source/target 21)

Namespace Migration — Jakarta EE 10

  • All javax.ws.rs.* imports replaced with jakarta.ws.rs.* across source files

  • web.xml updated to Servlet 6.0 schema (<https://jakarta.ee/xml/ns/jakartaee)>

  • context.xml cleaned up — removed deprecated antiJARLocking attribute (removed in Tomcat 9.0) and redundant path attribute

What Did NOT Change

  • Cisco JTAPI integration (javax.telephony.*) — unchanged, this is Cisco-proprietary and not related to Jakarta EE namespace migration

  • config.properties and jtapi.ini configuration format

  • Finesse Gadget files (Gadget/Whisper_Coaching/) — deployed separately on Cisco Finesse, no changes required
