I am following this tutorial

http://download.jboss.org/jbosstools/nightly-docs/en/jsf_tools_tutorial/pdf/JSF_Tools_Tutorial.pdf

and I am getting this warnning in the inputname.jsp:The tag handler class for "h:form" (com.sun.faces.taglib.html_basic.FormTag) was not found on the Java Build Path.

At the end, I got this error when I tried to access http://localhost:8080/jsfHello/index.jsp

Hi

this could be Cause 1
       If we are including any input type components that should be the child of form component.

<h:form id="greeting">
    Please enter name:"

      <h:inputText id="name" value="#{personBean.name}"/>
</h:form>

Please make sure that it is properly ended form tag.

Cause 2
          The tag handler class for "h:form" (com.sun.faces.taglib.html_basic.FormTag) was not found on the Java Build Path.

Please add corresponding jar (jsf-impl.jar) that suits ur requirment.

If it doesnot solves the problem. please share ur code snippet.

Cheers,
Sreemanth.
