My environment is AEM6.2 with all the patch installed, i read through the sling jira SLING-7044 and i saw it solved on Scripting JSP 2.3.2 , and i tried to upload the scripting jsp 2.3.2 bundle from the sling website, it didn't work either
Either the bundles containing those tag libraries haven't been deployed and you need to do that, or they have been deployed but they aren't starting because of dependency versions. You may need to download the latest versions of those bundles and deploy them - in which case you may need to update your URI since I think they changed them to remove the wem references.
i don't own this custom taglib, it's from other vendor. but it seems working functional on other environments without having the scripting jsp 2.3.2.
i think the taglib bundle is fully installed by checking the /system/console/bundles page, all bundles are active and the /system/console/status-jsptaglibs page, it shows below the Currently available JSP Taglibs.
Also i checked the bundle has the missing helloWorld.tagx in the right place. i extracted the bundle, it's in the /META-INF/tags/helloWorld.tagx.
If you experience issues that should work after an update - please contact support. Sometimes after an upgrade - a hotfix may be needed. We have seen things that work on Fresh installs not work on upgraded versions.
