classNotFoundException : Javax.Servlet.Jsp.Jstl.Core.Config
Are you trying to leverage JSTL tags in JSP but getting classNotFoundException? This might be the case if you are deploying your web application in tomcat (I came across this while migrating from one container to other). Many JEE containers provides this, but not tomcat.
To solve this, Include following dependency in project to fetch the jar and bundle it with library
<dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency>
