There Was A Problem With An Error Parsing The Spring.tld Tag Library Descriptor

So if you sometimes do JSTL 1.0 in jars in the classpath folder (in WEB-INF / lib), but specify the URI from the taglib directive “http://java.sun.In com / jsp / jstl / core” , you get the following error situation.

By the way, ifand you are new to servlets in the JSP world, you can also compare these free servlets and JSPs to help your courses learn the basic JSP and JSTL requirements that are important to use these label libraries contained in your project. yes

What “Definitely Cannot Find The Tag Library Descriptor”

When the JSP generator wants to use a custom tag, it imports it using the taglib directive that takes a URI. The web container looks for this URI and looks for it in all the specific descriptors of the tag library, available in four places:

3) Internal META-INF directory, most often associated with JAR file stored in WEB-INF / lib folder

4) In the META-INF subdirectory inside the JAR file which is located in WEB-INF / lib

In this case, if all web containers cannot find this URI, it will result in the error “The tag library descriptor cannot usually be found” followed by a URL that it cannot buy. So, in our case, the error lesson is: “Could not find the library header descriptor for” http://java.sun.com/jsp/jstl/core “, which means the firewall cannot find the TLD filesfor the URI “http: / /java.sun.com/jsp/jstl/core”, which is for the JSTL base tag library version 1.1.

Since the JSTL tag libraries are in the supplied standard.jar file, you can have this JAR in the classpath of your web application, for example WEB-INF / lib. Almost all JSTL TLDs for tags like core, xml SQL and link are actually in the META-INF folder for standard.jar.

So the first step is to check if the standard.jar and JSTL.jar files in the WEB-INF / lib folder are appropriate. or copy it from your winning host.

Sometimes you get the error “The tag library descriptor for http://java.sun.com/jsp/jstl/core” cannot be determined after you have jstl.jar and standar.jar in your path. Main class or WEB – INF / lib directly, if easy check JSTL version and standard .jar.

Since the URI is different in JSTL 1.1 and JSTL 1.0, you must use the correct version of the JAR that matches the URI you are using in your JSP page.

This means you are using http://java.sun.com/jsp/jstl/core and adding jstl, the standard JAR 1.1. AND

If you are using http://java.sun.com/jstl/core (without URI In / jsp) add JSTL 1.0 and JAR level 1.0 to WEB-INF-Lib. you tooYou can check out these Best Servlet and JSP Courses to learn more.

Shortcuts

1) Make sure standard.jar is in the classpath because it contains the TLD.

3) Make sure customer 1 is using jstl.1 and standard JAR 1.1 as the URI “http://java.sun.com/jsp/jstl/core” requires JSTL1.1 package files

4) Use uri like “http://java.sun.com/jstl/core” if you are using JSTL with 1.JAR 0 you will see there is no JSP in URI.

This is almost a fix for the error “In fact, you can find the tag library descriptor from the name” http://java.sun.com/jsp/jstl/core “which is different in JSTL 1.1 and JSTL 1.0 in a Java web application. You should use that the specific correct JAR version that matches the specific URI you are using in your JSP page, and you have to use multiple versions of the JAR files depending on the actual URI you are using in the JSP file.
