我想在我的 jsf 页面中包含一个 js 文件。我尝试了通常的方法，但没有成功。

<script language="Javascript" type="text/javascript" src="js/alertMessages.js"></script>

我还尝试了如下的 adf 组件：但是我的 adf 库中没有 af:resource 组件。

<af:document>
  <f:facet name="metaContainer">
    <af:resource source="/mySourceDirectory"/>
  </facet>
  <af:form></af:form>
</af:document>

请让我知道如何在我的页面中包含 js 文件。

谢谢...

相对资源 URL（

因此，如果您通过以下方式打开页面

http://localhost:8080/contextname/somefolder/page.jsf

然后是脚本您所拥有的文件实际上会从以下位置下载

http://localhost:8080/contextname/somefolder/js/alertMessages.js

代替

http://localhost:8080/contextname/js/alertMessages.js

您想要使 URL 相对于域根。所以它必须变成/contextname/js/alertMessages.js。您可以使用 ${pageContext.request.contextPath} 动态内联上下文路径：

<script type="text/javascript" src="${pageContext.request.contextPath}/js/alertMessages.js"></script>

请注意，language 属性是多余的。另请注意，对于 JSF 2.x，有一些可用的标记可以隐式执行此操作，例如。

另请参阅：

Relative resource URLs (the URLs of <script>, <link>, <img> and <a> elements which do not start with scheme http:// or slash /) are relative to the current request URL (as you see in browser address bar).

So if you're for example opening the page by

http://localhost:8080/contextname/somefolder/page.jsf

then the script file as you have there will actually be downloaded from

http://localhost:8080/contextname/somefolder/js/alertMessages.js

instead of

http://localhost:8080/contextname/js/alertMessages.js

You would like to make the URL relative to the domain root instead. So it must become /contextname/js/alertMessages.js. You can use ${pageContext.request.contextPath} to inline the context path dynamically:

<script type="text/javascript" src="${pageContext.request.contextPath}/js/alertMessages.js"></script>

Note that the language attribute is superfluous. Also please note that for JSF 2.x there are tags available which do that implicitly like <h:outputScript>.
