Eclipse + JSF + Facelets + composite component = CANNOT_FIND_FACELET_TAGLIB

Question

I'm trying to add a composite component to my JSF Facelets application.

The composite component (email.xhtml) is as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:composite="http://java.sun.com/jsf/composite"
    xmlns:h="http://java.sun.com/jsf/html">

<h:head>
    <title>This content will not be displayed</title>
</h:head>
<h:body>
    <composite:interface>
        <composite:attribute name="value" required="false" />
    </composite:interface>

    <composite:implementation>
        <h:outputLabel value="Email id: "></h:outputLabel>
        <h:inputText value="#{cc.attrs.value}"></h:inputText>
    </composite:implementation>
</h:body>
</html>

The using page (emailuserpage.xhtml) is as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:em="http://java.sun.com/jsf/composite/emcomp/">

<h:head>
    <title>Using a sample composite component</title>
</h:head>

<body>
    <h:form>
        <em:email value="my@email.address" />
    </h:form>
</body>
</html>

The path to my composite component is src/main/webapp/resources/emcomp/email.xhtml . The path to my user page is src/main/webapp/emailuserpage.xhtml .

But I get both compile time and run time warnings in emailuserpage.xhtml, and nothing (besides a warning message) gets displayed in the browser

Compile time warning shown in Eclipse JSF HTML editor:

xmlns:em="http://java.sun.com/jsf/composite/emcomp/"
NLS missing message: CANNOT_FIND_FACELET_TAGLIB in: 
 org.eclipse.jst.jsf.core.validation.internal.facelet.messages

Run time warning shown in Eclipse browser (javax.faces.PROJECT_STAGE=Development in web.xml):

Warning: The page /emailuserpage.xhtml declares namespace http://java.sun.com/jsf/composite/emcomp/ and uses the tag em:email , but no TagLibrary associated to namespace.

I've already seen this question (it didn't solve the problem): NLS missing message: CANNOT_FIND_FACELET_TAGLIB

I'm using the m2e and m2e-wtp plug-ins, with Eclipse version:

Eclipse Java EE IDE for Web Developers
Version: Indigo Service Release 2
Build id: 20120216-1857

Any ideas on what I'm doing incorrectly? Have I included the composite component incorrectly somehow, or am I using the wrong directories to store my resources? Is this an Eclipse/configuration problem?

[EDIT]

In response to Daniel's comment

SOURCE directory structure:

project/src/main/
- java/
- webapp/

DEPLOY directory structure:

project
- HTML files
- resources/ (including emcomp/ folder)
- META-INF/
- WEB-INF/ (config files and lib/ folder)

从XML名称空间URI中删除尾部斜杠。

xmlns:em="http://java.sun.com/jsf/composite/emcomp"
