java - <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> -

when add following line in faces-config.xml file:

" <application><view-handler>com.sun.facelets.faceletviewhandler</view-handler></application> " 

eclipse says:

" view-handler references "com.sun.facelets.faceletviewhandler" not implement interface javax.faces.application.viewhandler  configure problem severity preference 'invalid view handler' " 

however, added libraries in "lib" of "web-inf" of jsf project. when deploy ear , jsf projects, deploy correctly, execution of jsf page, error:

it you're mixing jsf 1.x, facelets 1.x , jsf 2.x. you've there jsf 2.0 compatible faces-config.xml root declaration, you're still declaring managed beans , navigation cases legacy jsf 1.x way (those entries not needed anymore in jsf 2.x @mangedbean annotation , implicit navigation feature). perhaps reading wrong books/tutorials/resources while attempting learn jsf 2.x.

also, viewhandler implementation mentioned there facelets 1.x necessary when you're still using legacy jsf 1.x. however, since jsf 2.x, facelets 2.x bundled in jsf api/implementation jars , has become default view technology, there no need have separate facelets jar file nor manually register view handler in faces-config.xml.

the tag error on <h:head> confirms you're using jsf 1.x jars during runtime instead of jsf 2.x <h:head> introduced in jsf 2.x , absent in jsf 1.x.

get rid of jsf 1.x , facelets 1.x related jars , make sure you've downloaded , installed jsf 2.x ones (or don't download jboss 6x ships jsf 2.x bundled, having empty /web-inf/lib should sufficient in order jsf 2.x run). throw away jsf 1.x books/tutorials/resources , head jsf 2.x ones. our jsf wiki page starting point.

as xml configuration files, ultimately, should end empty faces-config.xml , only following entry in web.xml:

<servlet>     <servlet-name>faces servlet</servlet-name>     <servlet-class>javax.faces.webapp.facesservlet</servlet-class>     <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>     <servlet-name>faces servlet</servlet-name>     <url-pattern>*.xhtml</url-pattern> </servlet-mapping> 

add if necessary primefaces theme back, if default of "aristo" isn't want.
