CA Web Viewer 12.1 No reports showing up after upgrade to Tomcat 9.0.31

Products

• Output Management Web Viewer

Issue/Introduction

When clicking on the “advanced search” tab, reports are not showing up and there’s nothing under the other tabs either, like “Configuration”. 

When we starting Tomcat7 from backup everything works. 

Environment

Release : 12.1

Component : CA OUTPUT MANAGEMENT WEB VIEWER FOR ALL PLATFORMS

Resolution

1) JDK is required to install the Tomcat service with Tomcat 9  (not needed after that?)
2) Service.bat requires classloader in JVM options.
set "CLASSPATH=%CATALINA_HOME%\bin\bootstrap.jar;  
3) The service must run as a Local System Account

reminder: run startup.bat as admin.
