Java – correct TLD file header

I wanted to create a custom tag, but I got "XML parsing error" on the JSP version line I checked my JSP version and it was exactly 2.1 I think the link is wrong

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems,Inc.//DTD JSP Tag Library 1.2//EN"
    "http://java.sun.com/j2ee/dtd/web-jsptaglibrary_1_2.dtd">
<tlib-version>1.0</tlib-version>

<jsp-version>2.1</jsp-version>

Who can help me? thank you

UPD / ERROR MESSAGE：org. apache. jasper. Jasperexception: unable to initialize tldlocationscache: org apache. jasper. Jasperexception: file / WEB-INF / TLDs / tag XML parsing error on TLD: (line 11, column 2)

Solution

You are using the DTD style declared by the old JSP 1.2 tag library You need to delete it (and < JSP version >) and use the new JSP 2.1 XSD declaration:

<?xml version="1.0" encoding="UTF-8" ?>
<taglib
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd"
    version="2.1">

    <!-- Taglib config here -->
</taglib>

Make sure you are reading the correct books / tutorials for JSP 2.1, not JSP 1.2
