Hello every one, Now i'm working on a jsf 2.0 project which the implementation is done with Apache MyFaces 2.1.6 (Final) and an optional components librairie RichFaces 4.2.0 in eclipse Helios as the develeppement environnement, the problem is what jars should i do knowing that i have add every jar which seems to be primordial to my class path project : commons-beanutils-1.8.3.jar commons-codec-1.3.jar commons-collections-3.2.jar commons-digester-1.8.jar commons-discovery-0.4.jar commons-logging-1.1.1.jar myfaces-api-2.0.2.jar myfaces--impl-2.0.2.jar richfaces-components-api-4.2.0.Final.jar richfaces-components-ui.4.2.0.Final.jar richfaces-core-api-4.2.0.Final.jar richfaces-core-impl-4.2.0.Final.jar Moreover i have used the eclipse assistant to download jars of MyFaces from Internet, so i would think that there's a problem of compatibility between eclipse if i had done this by my self but it was done by eclipse itself ! when i create a new Facelet template from an XHTML file, i still having a warning saying :
Multiple markers at this line - Warning: unknown attribute "xmlns:f" - Warning: unknown attribute "xmlns:ui"- Warning: unknown attribute "xmlns:h" Eclipse don't recognize these namespaces : xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"xmlns:ui="http://java.sun.com/jsf/facelets" The most strange thing is that when i create a jsp file (new javaServer Faces page (xhtml) ), it works normally without any warning or errors !! What should i do please :) Thanks.
