Denden,
I have same problem.
the root cause is the version of Mojarra2.0.0
if you open jsf-impl.jar,
there is a file: META/taglib/ui.taglib.xml
notice the tag remove
tag-nameremove/tag-name
handler-class/handler-class
handler-class is NOT defined.
this would cause a problem and
Denden,
I have the same problem as you.
I found the root cause.
The library jsf-impl.jar you(and I ) is in downloaded zip file:
mojarra-2.0.0-FCS-binary.zip.
if you open jsf-impl.jar, there is a file: META-INF/taglib/
ui.taglib.xml.
at the end of this file:
tag-nameremove/tag-name
