I am trying to implement menus in JSF which I was able to do it.

menucontents.jsp:

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<html>
<head>
  <meta HTTP-EQUIV="Content-Type" CONTENT="text/html;charset=UTF-8" />
  <title>MyFaces - the free JSF Implementation</title>
  <link rel="stylesheet" type="text/css" href="<%= request.getContextPath() %>/pages/css/basic.css" />
</head>
<body>
<f:view>
    <f:loadBundle basename="com.cpc.resources.menu" var="menu"/>
    <t:div id="hNav_outer">
        <t:panelNavigation2 id="nav1" layout="list" itemClass="off" activeItemClass="on" openItemClass="on"
                            renderAll="true">
            <t:commandNavigation2 value="#{menu['menu_Home']}" style="padding-left: 0px;">
                <t:commandNavigation2>
                    <f:verbatim>&#8250; </f:verbatim>
                    <t:outputText value="#{menu['menu_Home']}"/>
                </t:commandNavigation2>
            </t:commandNavigation2>
            <t:commandNavigation2 value="#{menu['menu_admin']}" style="padding-left: 150px;">
                <t:commandNavigation2>

                    <t:outputText value="#{menu['menu_admin_change_password']}"/>

                <t:commandNavigation2>

                </t:commandNavigation2>
            </t:commandNavigation2>

        </t:panelNavigation2>
    </t:div>
</f:view>
</body>
</html>

menu.jsp:

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<html>
<head>
  <meta HTTP-EQUIV="Content-Type" CONTENT="text/html;charset=UTF-8" />
  <title>MyFaces - the free JSF Implementation</title>
  <link rel="stylesheet" type="text/css" href="<%= request.getContextPath() %>/pages/css/basic.css" />
</head>
<body>
<f:view>

<f:subview id="headerinclude1">
    <jsp:include page="menucontents.jsp" />
</f:subview>
</f:view>
</body>
</html>

I have tried various combinations i.e by removing the HTML / BODY / f:view tags but nothing seems to be working I know somewhere I am doing it wrong not able to check it. Any help would be appreciated.

Also, the first part of code when executed as an single file it works very well the only problem is when I include it in another JSP the menus are not getting displayed.

The <f:subview> has to go in the include file, not in the parent file. Replace the <f:view> in menucontents.jsp file by <f:subview> and remove the <f:subview> from the menu.jsp.

Summarized:

menu.jsp

<f:view>
    <jsp:include page="menucontents.jsp" />
</f:view>

menucontents.jsp

<f:subview id="menucontents">
    <f:loadBundle basename="com.cpc.resources.menu" var="menu"/>
    ...
</f:subview>

(note that the include file should not have a <f:view>, you also don't need a HTML head/body around it, that would only produce invalid HTML)
