[jboss-jira] [JBoss JIRA] (WFLY-1172) mechanism to load tag libraries from module

[Brad Maxwell (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-1172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12792549#comment-12792549 ] 

Brad Maxwell commented on WFLY-1172:
------------------------------------

In AS 7.2 and greater, you just need to add meta-inf="export" or import to your jboss-deployment-structure to pull in META-INF.  This makes them available on the classpath and you can locate them with Thread.currentThread().getContextClassLoader().getResource("/META-INF/mytaglib.tld") , however I believe the jsp spec or such only loads META-INF/*.tld from jars in the application, it does not check the classloader.  So the change is likely a feature extension of the spec to scan the classloader for tlds - such as in JBossWeb or Undertow.

> tag libraries are scanned only if they appear in jar inside WEB-INF/lib or are defined in tld under WEB-INF.
> The simplest scenario to explain why this is a problem: portlet 2 defines standard portlet taglib, but the classes in this file come from concrete implementations. Currently I see no way to use 2 different portals in a portable way.
> Please provide a way to notify a relevant subsystem for web applications that specific module contains a .tld.
