I am facing an issue during deployment of a service in Tomcat 8. Getting following error :
Caused by: java.lang.NoSuchMethodError: javax.servlet.Ser
Check all your Maven (or equivalent) dependencies and make sure that you - or most likely another dependency - are not pulling in a pre-3.1 version of the javax.servlet / servlet-api
that may be taking precedence over what's in your Tomcat 8. If you've manually deployed, make sure you haven't manually copied any servlet-api JARs into Tomcat itself.
