I am not sure where to ask this, but I will try it here: I searched half a day (that is: downloaded and searched thru its content) ALL the org.springframework.web.servlet jars from the very first release (2.5.6) till the latest one (3.2.2) but I am unable to find/locate one specific library that should be there called "CorsRegistry.java" (org.springframework.web.servlet.config.annotation.CorsRegistry).
This specific library is needed for the "Document Viewer Java Library" (beside quantum of many other jars).
Can anyone point me to the correct download location of the file that would include this specific library?
>Solution :
I can see this class in the latest spring-webmvc-5.3.19.jar
-> jar -tf spring-webmvc-5.3.19.jar | grep "CorsRegistry"
org/springframework/web/servlet/config/annotation/CorsRegistry.class
