I using tomcat 10 and it's standard libraries, in this case the jsp-api.jar with contains the Taglib. Since tomcat 10 all the components are renamed from javax to jakarta and the jstl is changed from http://java.sun.com/jsp/jstl/core to a new URI that i searching for.

I receive the error on eclipse "can not find the tag library descriptor http://java.sun.com/jsp/jstl/core"

When i run the application after successfully compile i receive at runtime the error exception:

"Die absolute URI: [http://java.sun.com/jsp/jstl/core%5C] kann weder durch web.xml noch durch die JAR-Files dieser Anwendung aufgelöst werden"

I expect to find the URI for the tomcat 10 standard JSTL library

I try:

\<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %\>

I expect:

<%@ taglib uri="the new uri hier..." prefix="c" %>

  • The URI has not changed. See https://stackoverflow.com/tags/jstl/info – rickz Nov 11 '22 at 02:27
  • `http://java.sun.com/jsp/jstl/core%5C` is indeed not the same as `http://java.sun.com/jsp/jstl/core`. And further the `jsp-api.jar` does absolutely not contain JSTL. – BalusC Nov 11 '22 at 09:08
  • You should follow the directions given at info page. Remove the other jars. – rickz Nov 11 '22 at 17:15
  • After deploying the JSTL Version 2.0 as explaned in the info all is working. close this issue and thanks a lot. – Roberto Gonzalez Nov 12 '22 at 00:56
