I am getting this error org.apache.jasper.JasperException: The absolute uri: <requiredURI> cannot be resolved in either web.xml or the jar files deployed with this application. Although the required jar is present in the classpath I am still facing this issue. But if I insert the same jar into web-inf/lib folder the error seems disappear. I do not want to put this jar in the lib folder as it is already included in the classpath. Any suggestion to resolve this issue?
