Load taglibs in module for JBoss 7
----------------------------------

                 Key: AS7-2522
                 URL: https://issues.jboss.org/browse/AS7-2522
             Project: Application Server 7
          Issue Type: Feature Request
          Components: Modules
    Affects Versions: 7.0.2.Final
         Environment: Linux Debian 2.6.32 (Squeeze)
            Reporter: Juan Manuel Medina Apodaca
            Assignee: David Lloyd

The taglibs contained in a module are not loaded for an application which uses such module.

For example, when trying to use Tiles in a web application with Jboss 7.0.2, I added
the necessary modules for Tiles to get loaded, but when a tiles page is shown, 
the "http://tiles.apache.org/tags-tiles" taglib is not recognized.

At web.xml, I added the listener and the servlet, which work fine:

   <listener>
    <listener-class>org.apache.tiles.extras.complete.CompleteAutoloadTilesListener</listener-class>
   </listener>
   <servlet>
    <servlet-name>Tiles Dispatch Servlet</servlet-name>
    <servlet-class>org.apache.tiles.web.util.TilesDispatchServlet</servlet-class>
   </servlet>
   <servlet-mapping>
    <servlet-name>Tiles Dispatch Servlet</servlet-name>
    <url-pattern>*.tiles</url-pattern>
   </servlet-mapping>

In the page, the taglib is declared:

   <html xmlns="http://www.w3.org/1999/xhtml"
        xmlns:h="http://java.sun.com/jsf/html"
        xmlns:f="http://java.sun.com/jsf/core"
        xmlns:ui="http://java.sun.com/jsf/facelets"
        xmlns:tiles="http://tiles.apache.org/tags-tiles">

Finally in one of the modules, tiles-jsp-2.2.2.jar is present with the taglib:

     <tlib-version>1.2</tlib-version>
     <short-name>tiles</short-name>
     <uri>http://tiles.apache.org/tags-tiles</uri>

The tiles module is referenced by configuration at the pom.xml:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-war-plugin</artifactId>
          <version>2.1.1</version>
          <configuration>
            <archive>
              <manifestEntries>
                <Dependencies>org.apache.tiles</Dependencies>
              </manifestEntries>
            </archive>
          </configuration>
</plugin>

I know that tiles is referenced by the application because, if I delete the configuration
section above, the application doesn't deploy since some referenced libraries are not present.

Shouldn't the taglib be automatically loaded as the module is included as a dependency?

At the resulting page, the following message is displayed:

Warning: This page calls for XML namespace
http://tiles.apache.org/tags-tiles declared with prefix tiles but no
taglibrary exists for that namespace.
