Such issues are seen when custom JAR files have been placed in the "<spotfire server installation directory>\tomcat\lib" directory.
If so, move them to "<spotfire server installation directory>\tomcat\custom-ext" (or remove them if not needed), and then restart the Spotfire Server Service.

You may also encounter this issue when there are duplicate JAR files in "<spotfire server installation directory>\tomcat\lib or "<spotfire server installation directory>\tomcat\webapps\spotfire\WEB-INF\lib". If so, remove the duplicates, and then restart the Spotfire Server Service. 

This knowledge base article explains how to resolve "Error creating bean with name ‘spotfireCa’ defined in class path resource" which is seen the Spotfire Server log (server.log)
