我正在研究Primefaces用户指南中的primefaces主题。 https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/primefaces/primefaces_users_guide_3_3.pdf在pag。 457你可以读到：“一旦你下载了主题，配置PrimeFaces使用它
<context-param>
<param-name>primefaces.THEME</param-name>
<param-value>aristo</param-value>
</context-param>
我应该把它放在哪里？进入我正在开发的网页文件？ 我选择了Redmond主题的jar文件，然后将其导入Eclipse Dynamic web项目，但我没有看到任何改进。
我正在测试的Primefaces示例是：https://www.primefaces.org/showcase/ui/data/datatable/basic.xhtml

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>
<param-name>org.apache.myfaces.ALLOW_JAVASCRIPT</param-name>
<param-value>true</param-value>
</context-param>
<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>

<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'

用户告诉我必须编辑

你必须把主题jar放在你的WebContent / WEB-INF / lib文件夹中，我不知道你是如何部署项目的，所以你可能不得不把primefaces jar放在那里，所以它会是在已部署的项目中。
随着jar的到位，您必须编辑web.xml文件以指示您将使用的主题。以Redmond为例：
<context-param>
<param-name>primefaces.THEME</param-name>
<param-value>redmond</param-value>
</context-param>
