Org. apache. jasper. compiler. TldLocationsCache tldScanJar, org. apache. jasper

When I click query on the page, the console contains the following red text:

15:09:27 org. apache. jasper. compiler. TldLocationsCache tldScanJar
Information: At least one JAR was scanned for TLDs yet contained no TLDs. enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

As shown in the console, it takes a minute or two to get stuck. That is to say, the data has been queried in the background, but the page is not displayed. The reason is that tomcat verifies the el expression on the page.

Solution: Include <! ----> Just remove the comment.

Question about tomcat 7014 JSP page access

TLD is a tag definition document that defines the location of a TLD when you introduce a tag library.

For example:
<% @ Taglib uri = "/WEB-INF/struts-tiles.tld" prefix = "tiles" %>
<% @ Taglib uri = "java.sun.com/jsp/jstl/core" prefix = "c" %>

It can be seen that there are two ways to introduce, first local, second remote

From your exception, you should introduce it locally.
But the file does not exist.

Three solutions: 1 change to remote Introduction 2 copy TLD file to local 3 modify log configuration without printing warning information

What do the following information mean?

File package missing
