While I'm trying to include the tag returned from class implementing javax.servlet.jsp.tagext.TagSupport, I'm getting *java.lang.ClassCastException: class name (implementing javax.servlet.jsp.tagext.TagSupport tag) incompatible with javax.faces.component.UIComponent*. The configuration being made as follows : *xhtml file:* <ui:composition xmlns=" http://www.w3.org/1999/xhtml http://www.w3.org/1999/xhtml" xmlns:ui=" http://java.sun.com/jsf/facelets http://java.sun.com/jsf/facelets" xmlns:h=" http://java.sun.com/jsf/html http://java.sun.com/jsf/html" xmlns:f=" http://java.sun.com/jsf/core http://java.sun.com/jsf/core" xmlns:rich=" http://richfaces.org/rich http://richfaces.org/rich" xmlns:a4j=" http://richfaces.org/a4j http://richfaces.org/a4j" xmlns:sf=" http://www.springframework.org/tags/faces http://www.springframework.org/tags/faces" xmlns:melalogin=" http://sovelluksenvaihtolistatag.tag/customTags http://sovelluksenvaihtolistatag.tag/customTags"> *tag used as :* <melalogin:sovelluksenvaihtolistatag /> *taglib.xml:* <facelet-taglib> <namespace> http://sovelluksenvaihtolistatag.tag/customTags http://sovelluksenvaihtolistatag.tag/customTags</namespace> <tag> <tag-name>sovelluksenvaihtolistatag</tag-name> <component> <component-type>sovelluksenvaihtolistatag.component</component-type> </component> </tag> </facelet-taglib> *faces-config.xml:* ** <component>    <component-type>sovelluksenvaihtolistatag.component</component-type>    <component-class>com.tieto.tkp.login.SovelluksenVaihtoListaTag</component-class>   </component> *web.xml:* ** <context-param>   <param-name>facelets.LIBRARIES</param-name>   <param-value>/WEB-INF/sovelluksenvaihtolistatag.taglib.xml</param-value> </context-param> Does the facelet support the jsp tag? Is there any additional configurations to be made?
