Hello Web Viewer r14 customers,
This is notice of an important runtime change starting with the July 2025 Web Viewer r14 PTF (LU17323). Earlier maintenance levels are not affected.
Beginning with PTF LU17323 and later, Web Viewer r14:
· Requires Java 17 or Java 21
· Requires Apache Tomcat 10.x
· No longer supports IBM WebSphere Application Server (traditional)
· Supports IBM WebSphere Liberty 23.x or later
Web Viewer r14 maintenance prior to July 2025 (June 2025 and earlier) continues to support Java 8/11, Tomcat 9.x, and existing supported application server configurations.
If you are currently running Java 8 or Java 11, you may remain on a June 2025 (or earlier) PTF without change. However, to apply PTF LU17323 or any later maintenance, your environment must first be upgraded. If Java 8/11, Tomcat 9, IBM WAS (traditional), or an earlier Liberty version is still in use, the July 2025 (and later) PTFs will not deploy or run.
This change standardizes Web Viewer r14 on modern, long-term support runtimes, improving security, simplifying support, and keeping pace with current Java and application server ecosystems.
Before applying PTF LU17323 or later, please confirm the Java version, servlet container, and application server in each environment and plan any required upgrades.
