私は JSF が初めてで、単純な jsf アプリケーションを作成しています。Tomcat を使用してアプリケーションを実行しようとすると 404 エラーが発生しますが、その理由がわかりません。Eclipse からではなく、Eclipse からアプリケーションを実行しようとしましたが、どちらも機能しません。localhost:8080/testing/faces/index.jsp、localhost:8080/testing/index.jsp、localhost:8080/testing/ など、複数の異なる URL (すべて大文字と小文字が区別されます) を試しましたが、どれも機能しません。私の知る限り、ファイルはすべて正しい場所にあります (jsp ファイルは WebContent の下にあり、web.xml と faces-config は WEB-INF にあります)。私のコードの何が問題なのか誰にもわかりませんか? web.xml と faces-config を以下に貼り付けました。

This parameter tells MyFaces if javascript code should be allowed in
the rendered HTML output.
If javascript is allowed, command_link anchors will have javascript code
that submits the corresponding form.
If javascript is not allowed, the state saving info and nested parameters
will be added as url parameters.
Default is 'true'</description>

<context-param>
  <description>
    If true, rendered HTML code will be formatted, so that it is 'human-readable'
        i.e. additional line separators and whitespace will be written, that do not
        influence the HTML code.
        Default is 'true'

  <description>
If true, a javascript function will be rendered that is able to restore the
former vertical scroll on every request. Convenient feature if you have pages
with long lists and you do not want the browser page to always jump to the top
if you trigger a link or button action that stays on the same page.
Default is 'false'
