> Jasper's technique for finding Tag Library Descriptors (TLDs) does not work
> well with Geronimo's MultiParentClassLoader. The Jasper compiler tries to
> find TLDs in jar files by getting the list of jars from the webapp's
> classloader and scanning them for META-INF/\*\*.tld. Then it repeats this
> process up the classloader hierarchy (at least what it *thinks* is the
> classloader hierarchy) by calling ClassLoader.getParent(). That works OK
> when then TLDs are in the webapp's WEB-INF/lib or in the JRE's system or
> application classloader. But this technique doesn't work in Geronimo because
> there are sometimes jars in the classloader hierarchy that are only
> accessible by using Geronimo's special MultiParentClassLoader.getParents()
> method.
> The Jasper code referred to above can be viewed in the scanJars() method of
> this class:
> http://svn.apache.org/repos/asf/tomcat/tc6.0.x/tags/TOMCAT_6_0_10/java/org/apache/jasper/compiler/TldLocationsCache.java
> Because of this limitation the Jasper compiler does not find the TLDs in
> myfaces-impl-2.0-SNAPSHOT.jar because it doesn't find the classloader
> containing that jar when it looks up the direct lineage of classloaders.
> This causes the following error message when a JSP refers to the JSF taglibs:
> {quote}
> javax.servlet.ServletException: The absolute uri:
> http://java.sun.com/jsf/html cannot be resolved in either web.xml or the jar
> files deployed with this application
> {quote}
> The MyFaces TLDs need to be made accessible to Jasper so that webapps can
> reference the JSF taglibs in their JSPs without copying the TLDs into their
> WARs.
