Error "File /META-INF/tags/HelloTag.tag not found" when creating custom JSP Tag lib

Hi All,

I am creating a JSP custom tag using tag file but i am getting following error

org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: File "/META-INF/tags/HelloTag.tag" not found

 

tag file is located at /META-INF/tags/HelloTag.tag

Following are content of tag definition file located at //META-INF/taglibs.tld

<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        http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_1.xsd" version="2.1">    <tlib-version>1.0</tlib-version>    <short-name>Angular</short-name>    <uri>http://abc.org/Hello/Taglib</uri>    <tag-file>        <name>Hello</name>        <path>/META-INF/tags/HelloTag.tag</path>    </tag-file></taglib>

Also following is the configuration of bundle plugin

 

<plugin>    <groupId>org.apache.felix</groupId>    <artifactId>maven-bundle-plugin</artifactId>    <extensions>true</extensions>    <configuration>        <instructions>            <Bundle-SymbolicName>org.abc.angularjs-tags-aem</Bundle-SymbolicName>            <Sling-Model-Packages>org.abc.web.jsp.angularjs.tags</Sling-Model-Packages>            <Bundle-Resource>/META-INF/tags</Bundle-Resource>            <Sling-Bundle-Resource>/META-INF/tags</Sling-Bundle-Resource>        </instructions>    </configuration></plugin>

I read following blogs for creating this sample.

        The issue was fixed in https://issues.apache.org/jira/browse/SLING-7044

        Summary of the issue :

        If a taglib in a bundle references a tag implemented as a script (located in /META-INF/tags) this script is not found as it is not searched within the bundle containing the tld - it's rather used as a resource on the classpath.

        Please contact Adobe to get the patch fix for this issue.

        Thanks

          I am getting same issue when migrating from AEM 6.1 to AEM 6.3. We did an inplace upgrade. How do I find obsolete bundles in my instance. I dont have above bundles mentioned by Stanleyor.

          Any thoughts what I need to check?

          Thanks in advance!

            I am using AEM 6.1 version.

            https://helpx.adobe.com/experience-manager/using/customtags.html talks about custom tag using Java class but in my case I am using tag file (*.tag file).

            Following is the jsp file

            <%@page session="false" %><%@include file="/libs/foundation/global.jsp" %><%@ taglib prefix="cq" uri="http://www.day.com/taglibs/cq/1.0" %><%@ taglib prefix="hello" uri="http://abc.org/Hello/Taglib" %><body data-ng-app="angularjsSample"  data-ng-controller="BaseController">    <hello:Hello target="World"/></body>

            Also following is the tag file.

            <%@ attribute name="target" required="true" rtexprvalue="false" type="java.lang.String" %><div> Hello <%=target%> </div>

            Okay, so it seems you are creating .tag files not .tld.

            You need to use /WEB-INF/tags as shown below

            JSP, sample.jsp

            <%@ page contentType="text/html" %> <%@ taglib prefix="my" tagdir="/WEB-INF/tags/myCustomTags" %> <html> <body> NAME : <my:name /> </body> </html>

            TAG, name.tag

            <%@ tag body-content="empty" %> <% out.println("AEM Developer"); %>

            Please see these:
