  2. Input Tomcat 9 as the tomcat home directory for the upgrade

Expected Results: Successfully upgrade to Clarity 15.9.3. 

Actual Results: 15.9.3 build fails while trying to validate Tomcat 9 directory. 


Release 15.9.3 



  • Impacts On-Premise customers using the interactive installation script for Clarity. 
  • SaaS and users of the silent installer will not have this problem. 
  • Tomcat web server which was tested and shipped with Clarity 15.9.3 is Apache Tomcat 8.5.65 and Tomcat 9.0.45.
  • Unable to upgrade to 15.9.3 when Tomcat 9 is used as home, and forced to upgrade using Tomcat 8 home and then later upgrade to Tomcat 9. 


  • Before doing the upgrade/installation, create file @ <installer extracted folder> with the entry: '15.9.3.j2ee.home=<tomcat 9 home directory>'.
  • Run 15.9.3 interactive upgrade by providing the Tomcat 8 home directory.
