    problem not solved…problem is….

    com.sun.facelets.tag.TagException: /default.xhtml @12,9 Tag Library supports namespace: http://java.sun.com/jsf/html, but no tag was defined for name: head

    i am developing through jsf 2.0+RichFaces 3.3.3.
    i have also included jsf 1.1.15.jar in my webinf/lib but the problem still not fixed..

    Since you are using JSF 2.0, you should not include the facelets jar, because JSF 2.0 already has facelets.

    Have a look at this StackOverflow

    I know ,but i am integrating jsf 2.0+ RichFaces3.3.3 ,and RF 3.3.3 does not support jsf VDL.
    so thats why i added facelet1.1.15,jar.

    I see. You probably read this article.

    I think RichFaces 3.x doesn’t really get along with JSF 2. I had problems myself in the past.
    Since you are using JSF 2.0, I suggest you to use RichFaces 4.x instead of 3.3.3.
    The rule of thumb is: use RichFaces 3.x together with JSF 1.2, but use RichFaces 4.x for JSF 2.0.
