Catalog 12.9 , 14.1, 17.x

Resolution

To check the tomcat version that your catalog is using , you can do the following : 
for example: suppose the URL for you to access your catalog GUI is : 
http://<hostname>:<port#>/usm/wpf 

if you purposely modify this URL a little bit and have it be a wrong one like this : 
http://<hostname>:<port#>/usm_abc 

and then you will get the HTTP 404 error and at the same time it will be able to tell you the tomcat version that your catalog is using , see the screenshot below :
