Java 17 Support with OM Web Viewer 12.1

Products

• Output Management Web Viewer

Issue/Introduction

Prior to this fix, attempting to run Web Viewer with Java 17 users experienced unexpected behavior and functionality failures. These included:

1. ·        Administration objects (such as users, repositories, or preferences) import and export functions failing to work correctly on the USS platform.
2. ·        The application failed to start up properly, specifically when attempting to load a DB2 license file.
3. ·        The configuration tool packaged with the application fails when trying test a connection to DB2

Environment

• Output Management Web Viewer 12.1
• Java 17
• IBM Db2

 

Cause

These issues stemmed from incompatibilities and limitations within our application code when run against the Java 17 environment.

Resolution

Cumulative build 255 introduces official and full product support for running our application with Java version 17. It resolves critical compatibility issues previously encountered when attempting to use the application with this Java version.

Web Viewer will start and run successfully with JAVA 17 and the DB2 database.  Import and export will function as expected.

This is the link to the resolution.
