I have been trying to configure the build path of the JSTL jar file in each and every tomcat server from the 8.5 version to 9 to 10 after adding the JSTL zar file to the path when I add the JSTL core tag it always throws an exception i.e. "org.apache.jasper.JasperException: The absolute uri: [http://java.sun.com/jsp/jstl/core] cannot be resolved in either web.xml or the jar files deployed with this application". For a better understanding of the issue I have shared the screenshots of all:
Here are the two projects having two different tomcat versions 8.5 and 9 and also the configuration of JSTL 1.2 is done
And the code in which the core tag is included
And the error
And ya it is not a maven project so no pom file.
